FAQs on Selenium Tutorial 25: Writing Test Cases using User defined Methods Video Lecture - Selenium Test Automation:Tutorial for Beginners (English) - Software Testing
| 1. What is Selenium? |  |
Ans. Selenium is a popular open-source framework used for automating web browsers. It allows testers to write test scripts in various programming languages and interact with web applications in a similar way as a user would.
| 2. What are test cases in Selenium? | |
Ans. Test cases in Selenium are a set of steps or actions that need to be executed to verify the expected behavior of a web application. These test cases are written using Selenium's programming language bindings and are used to automate the testing process.
| 3. How can user-defined methods be used in writing test cases in Selenium? | |
Ans. User-defined methods in Selenium allow testers to create reusable code blocks for common actions or functionalities. These methods can be defined once and then called multiple times within test cases, making test scripts more organized, modular, and easy to maintain.
| 4. Why is it important to write meaningful test cases in Selenium? | |
Ans. Writing meaningful test cases in Selenium is crucial for effective testing. Meaningful test cases clearly define the expected behavior or outcome of a web application and help in identifying any deviations or issues. They also make it easier for other team members to understand and execute the tests.
| 5. Can you provide an example of a user-defined method used in a Selenium test case? | |
Ans. Certainly! Here's an example:
```java
public class SeleniumTest {
WebDriver driver;
// User-defined method to login
public void login(String username, String password) {
driver.findElement(By.id("username")).sendKeys(username);
driver.findElement(By.id("password")).sendKeys(password);
driver.findElement(By.id("loginButton")).click();
}
// Test case using the login method
@Test
public void testLogin() {
driver = new ChromeDriver();
driver.get("https://www.example.com");
login("testuser", "password123");
// Assertions or further actions
driver.quit();
}
}
```
In this example, the `login` method is defined to perform the login action. It takes username and password as parameters and interacts with the relevant elements on the web page. The `testLogin` test case then uses the `login` method to perform the login action and can continue with further assertions or actions.

selenium class 25 writing test cases
part three see today we are going to
discuss writing selenium webdriver test
cases using user-defined methods or you
can say reusable components say writing
selenium webdriver selenium webdriver
test cases using user-defined methods
yowser yowser definite methods or you
can say reusable components reusable
components okay
first create user-defined methods create
user-defined methods say if we find more
reusable components in our project we
can reduce the project code size and
complexity we can reduce the project
code size so you try to find more
reusable components okay today I will
explain how to create user-defined
methods and how to use them in test
cases first you know how to create
user-defined methods see new
class class name suppose methods
you
okay now create user-defined method for
login functionality admin login
functionality
srivalli method definition before main
method na yes
before main measure ah create
user-defined method for login
functionality you know that login
functionality we have to send a username
and password okay say public static
static not required void suppose method
name admin login okay first I am
creating without arguments then you can
create with arguments also next creates
AB driver that web driver driver equal
to new oh good new Firefox train new
Firefox driver import import web driver
import Firefox driver next I'll launch
the tip admin homepage driver dot get
get or take that URL just a minute
belled admin
next enter a username saying this method
no arguments no arguments we have to use
constant values fixed values dot find
element by dot name username username
dot Zod Keys send Keys admin next same
password edit box only by dot name
password send Keys admin at one two
three next driver dot find element by
dot ID ID of TD beavin PDB 1 dot dot
click operation click just terminated we
check that element locators user name
name locator user name next password
name locator password next login button
ID locator pdb one ok next create one
more function this time with the ok you
just call this function just a call in
this function no verification point just
to play navigation call the function you
know how to call first parade out they
ask me
chaos name class name was to create
object you
the object you can access methods
methods suppose obj equal to new methods
good new methods just a minute
new methods semi-official on matched obj
dot only here dot admin login just run
Oh disable this antivirus it is showing
another element or run the program once
again
acute Inge here no verification point
okay next right one more statement in
this test a statement is driver dot
close driver dot no close method first
of all error okay
why say we created webdriver means we
create a sorry we created driver object
in this method this is local isn't it
yes sir we created driver object in this
method a block of code it is local make
it as global make it as global before
this method public public static
webdriver webdriver equal to web driver
driver equal to in Firefox new Firefox
driver new Firefox driver semicolon now
you remove the statement you can just
use driver run the program
now it is working now this extra
statement yes sir okay next create same
admin login method with arguments its
same name admin login suppose your
surname password say whenever you are
string string data type string username
string password whenever you want to
perform login with constant values you
call first method whenever you want to
use different inputs you call second
admin login method see methods with same
name Madhuri methods with same name in
the same class this concept is called
method overloading method overloading
say next if I want to call that one just
a minute
first I am calling that method after
that closing obj dot admin admin login
username admin comma password admin at 1
2 3
semicolon change the values in find
payment forum there are static values in
the headed yes have to change we need to
username is replace the constant values
with parameters replace constant values
with parameters username password don't
use double quotes for parameters next
try to run the program
era observe civil leader while Mikasa
here we are running the same already it
used first method no no that is it Ryoga
you can you can call a number of times
that is not the issue
we need the author's rights cooler okay
after Queen Malaga's we closer to the
browser log of not required that
webdriver launches fresh instance of the
application that is not the issue here
issue is we closed the browser now after
first method next what it is showing
error communicating with the remote
browser it may have died it is ended
okay yes ah here you write one method
for a closed browser also close browser
first set by existence of browser if
they exist then close if you exist then
close okay
public void comes close browser close
browser blank parent is no arguments
next here I am writing one condition
observe the condition if not not
exploratory symbol driver driver dot -
string dot contains contains null if it
is not null then close otherwise don't
driver dot closed instead of that one
you call that function obj dot closed
browser or try to run this program
still error okay
okay for launching browser also to write
the function for launching browser just
a minute how to write a function for
launching browser rahman write function
for loop launch application also like
our launch browser also okay public just
terminate launch browser just a minute
public static just terminate launch
browser launch browser this one admin
login
without parameters next admin loggin
just a minute admin login with
parameters with parameters next close
browser okay so you remove the statement
just a public static web driver driver
semicolon just we are declaring driver
next public void suppose
launch launch browser a launch browser
just a minute mother we tell me the
statement how to launch the browser we
declared web driver as static oh yes
driver no need to write web driver
we already declared driver equal equal
to yes new Firefox driver new Firefox
driver
okay now observe I only run the program
main method nullpointerexception
it did not call yawns oh oh good good
we didn't call that one obj dot launch
application launch browser first launch
bros um first you remove the statement
where our web browser statement not
available
okay okay first launch browser admin
login close browser launch login close
again launch obj dot launch browser
admin admin login with parameters
next close
okay run the program
first first iteration of our second
iteration okay now see only executing
now yes yes sir okay say for launch
browser also we need to write the
separate method see here you can create
a n number of user-defined methods just
terminate
creating user-defined methods next
create one more class suppose class test
the case one test case one suppose in
this in this case login admin login
verification I want verification say
admin otherwise for new tested redirect
redirect to user interface redirect to
user interface from admin interface from
admin interface see this is the test
case
okay next for redirecting first login
then redirect to user interface see
manual operation admin admin at 1 2 3
next click online catalog link online
catalog link are redirecting to user
interface you take this URL ok
ah write test case login login steps
available in that a login method 3 are
civilly yes sir we have to work impaired
object now edit I inherit inherited
chaos what is the key word foreigner in
here inheritance inherits mmm keyword
for inheritance extends attendance yeah
extends class name it measures ok
next create object was to create object
or you can say instance ah class name
what is the class name that's the case
one ah next object name suppose an
object equal to new it is also new class
name same class test the case one open
and close parenthesis and a semicolon
okay next ah
verification point first you write the
steps for a verification point first a V
director user interface and verify
before that you call a required methods
whoa GG r dot a yawns frozen launch
browser required type L select launch
browser okay next object dot admin yogin
admin logon object dot admin login see
here to admin logins available you can
use without arguments are with arguments
suppose with the arguments admin admin
at one two three okay admin at one two
three the first one also we accept both
ah next so the argument are without
argument what is difference in say
suppose with arguments with arguments
you can change the value now you can use
positive values or negative values for
this test case okay suppose if it is
fixed values you cannot change not yes
say observe suppose I want to conduct
admin login functionality verification
if we use a without I if it is without
arguments you can't use you can't change
the parameters now yes ok here we are
using valid inputs for login admin
functionality this method okay suppose I
want to check error message
functionality means invalid inputs
negative testing for that this method is
not suitable not yes
suppose if we use arguments what will
happen the
method can be used for positive testing
or negative testing both isn't it yes
find the difference between a method
with arguments method without arguments
what is the difference with arguments it
will be the fixed value we can't
transition we can't change the values
that that method can be used for
positive testing only if we use
arguments that that can be used for
positive and negative testing isn't it
yes ok Nanji are continuously only
driver dot next remaining statements
where we are just back-cast
onion online catalog this is linked
eggnog online catalog ok driver observe
in this test in this program I am not
creating the driver driver created in
main class this is subclass you are
inheriting the methods and variables we
are inheriting the class members
non-static class members driver dot cyma
and element by not linked extending
suppose link test value online catalog
catalog catalog operation click link
click next after a click then capture
captured I you are a string driver or a
stream you are with URL equal to driver
dot on driver driver dot
get current your get current URL
semicolon next right collision if you
are a quite equals URL dot dot a just a
minute
dot equals what is that value we already
captured that value okay next you can
write any meaningful message suppose sys
hope control space enter redirect Ana
redirected to user interface are we
directed to user interface user
interface pastas next else not read not
redirected to user interface user
interface file okay next after this
curly brace close the browser object
object dot kills close browser
ah observe pretty in this test case we
are using reusable components nothing
but user-defined methods na yes see
first we called one method next one
method net
we write normal statements and again
method see first first one first
statement method law statement method
middle some statements this test case
specific statements see first method
second one also method next normal
statements next last one again method
Rhonda Rhonda test case
of Kamala Kamala is there I think not
available
okay next and Krishna chaser now guide
me second best case just a minute I will
copy this one this is first test case
next my second test case using
user-defined methods login functionality
admin login yesterday we did that you
know the logic admin login functionality
just eminent admin login functionality
with valid inputs with valid inputs next
as the case admin login functionality
admin login functionality with invalid
inputs invalid inputs next test the case
of Jarama 3 the day you asked now can we
write multiple test cases in a program
yes we can write it with the help of
test ng you can write multiple test
cases in a program without without
testing gr j-unit framework also you can
write multiple test cases in a program
say
right multiple multiple test cases all
these three are redirect to user
interface admin functionality with valid
inputs admin login functionality with
invalid inputs all these three test
cases in single program write multiple
test cases in a program okay next guide
me pretty I want to the second one
srivalli gated me for first test case
redirect to user interface from admin
you have to get me for the second test
case admin login functionality with
valid inputs means check that admin
login create contest okay new new class
create new Java class pretty is next
what is the test case what is the test
case admin login functionality with
valid inputs positive test case here we
are not going to check invalid inputs
positive test the case see if it is
working for valid inputs or not what
about handling invalid inputs that is
another concern another scenario ah let
me first of a step we have to launch the
browser so we have to call the method
first fastest
up we are going to access user-defined
methods are reusable components from
another class first he inherit and yeah
it exchange extents or the class name
mid methods ok inherited next next step
create object object or you can say
instance of the class create object in
this class pretty quick here create
object in the sphere in this class
obj what is the syntax class name object
name equal to new class I know that it
is kiss to s the case to this is the
class name next object name your wound
you can use any name meaningful name
suppose obj two is equal to new tsk is
to new test case to new test case to
open and close preparin this semicolon
okay object Krishna over next observe
the requires a test steps for our login
functionality firstly you need it launch
the browser then large after login
captured the URL and compare with
expected okay login login test and all
that is there a login method already
there you call that login method next
for launch application also called
method first launch application Oh DJ to
blood type level one browser
okay next obj2 obj to dot admin login
admin loggin I am using just without
arguments with arguments also you can
use and you can pass parameters see
anyhow we used valid inputs now that is
why I am calling that one next
right normal steps after login you need
to capture you are in moral strength
think you are an URL equal 200 BG no no
driver driver not getting an enquiry
okay say we are accessing driver object
from main class parent class
this is sub class in this class we did
create the driver we are accessing
driver object from main class next write
the condition if you have a URL dot
contents for example you take that one
URL this is one
contains this one then you can write
meaningful message say sys for control
space enter next admin admin login is
successful successful status of results
for example positive else failed it
unsuccessful failed next after this
verification point close the browser
resident driver dot closed otherwise we
have method na ya obg to do not close
browser okay she observed in this test
case first first two steps of methods
calling next remaining steps except law
step normal steps next last step again
method calling method call the statement
is method call
okay run the program
observe the output breathing yes
admin login successful pass faster okay
next negative test case Madhuri just a
minute just a minute who is asking
Krishna Chaitanya yes tell me Krishna
Chaitanya is there other possibility
without checking that only the URL yes
other possibility is also there you can
use say verification points you can
consider different things
observe your log of link is there none
he says after login you can get logoff
link before large in know log off link
by checking the existence of log off
link you can confirm login functionality
isn't it
not only is oral see by clicking the
exit existence of log of link you can
you can confirm the login functionality
for that you need to write the exception
also checking object object existence
now exception required if it is URL URL
is fix it now yes that is why I am
taking easiest way you can use another
another ways also no issue you can write
your observed you take you take this one
as assignment personal assignment you
write verification point for login
functionality here you consider
verification check the existence of log
of link and confirm login here exception
also required now
suppose sometimes it it will show no
such element exception if login is not
successful not enough people had
successful forget about that one suppose
successful but logoff link not available
logout another name is available for
example safe side exception required now
we already used exception handling no
such element I think yesterday day
before yesterday day before this or day
before yesterday you using that syntax
you can write ok now ok observe good
question observe or verification points
there are no fixed ways you can consider
several things but select best method
here I am taking URL why URL is fix it
URL is fixative that is why I am taking
URL otherwise you can check the object
existence suppose log of link log of
link here observe before login before
login what is the link link login link
after login after login another link
another link what is that link index
page observe Krishna Chaitanya now index
page na instead say sometimes you can
consider page title also but in this
application page title duplicate absorb
here what is the page title GC Asha
admin are just a minute
what is the page
title for beef before logon page
Jessie oh sure admin same are different
that same same did you observe the
Santos are Amin did observe before login
page title is these are shop admin after
loggin also same page title so we cannot
consider page title for verification
suppose if page titles are changing
means unique page titles then you can
use that one also okay let's come to
Main Street ah
so can you open that term which one is
Edition application ah just a minute
ah tell me sir on the top it is
mentioned GCI shop that is that is that
is rain is it that is not the page title
that is only external image just a
minute abs or tooltip what is that run
GCR shop admin otherwise just a minute
place most point on the page and right
click view page source control F here
enter title page title
just a minute so many titles are here
observe a guru pretty what is the title
of the page title attribute ya GC
Arshavin that is the page title external
you is different internal value is
important
okay now yes say second one next test
case mother he gave me I'd been logging
functionality with it invalid inputs
negative test the case positive test
case over I am creating one more class
new class perspective that's the case or
two or three three now guide me from
scratch my requirement is this one
negative test case admin login admin
login functionality with invalid inputs
negative as a case first inherit aa
extents extents methods methods that
class name parent class name next create
object our instance
ah - Turkish three just a minute
pass the case three uh any name suppose
for identification purpose I am changing
object name different object names
suppose in test case to object to test
case three object three okay equal to
new test case three new test case three
open and close power on this semicolon
next yes object three dot launch browser
type L and select launch browser next C
object 3 dot admin login with parameters
observe pretty you ask Anna for this
negative test case with parameters only
is without if you call without
parameters in that we use a constant
values those are valid input isn't it
yes it is a admin for example invalid
input admin but actual user name is just
admin I am using incorrect username next
admin at one two three a password also
incorrect okay next
Archer the string nah what is that one
error message after invalid input you
can get error message now what is that
error message
this one from write that statement for
that one
just a minute
string you suppose error message equal
to sorry driver dot find element by dot
y dot just a minute here you can use
class message stack error message stay
care of just a minute by dot class name
class name locator value just a minute
. ah get this get it is not taking class
name any error by by dot class name okay
import by oh oh yes yes get texted okay
next here one condition required ah for
advancing we have to input yes by also
built in class what I'm asking it is not
we never did before right
see earlier sometimes it is
automatically imports just a minute
where is the trum method so you can
check
here in this main class by already
imported okay by is built in Class C
here open key a selenium by yeah okay a
continuum of a string error message okay
next we write the condition right
condition ah
tell me the condition if ah yes error
message error message dot equals dot con
tiles in this select this total one next
what is a problem ah right message
suppose control space enter handling
invalid inputs invalid inputs positive
next else not handling say ah not
handling
invalid inputs valid next after this
condition close browser dot close
browser run the program
but
say handling invalid inputs past next
rom on multiple test cases in a program
yes sir on you write a program for all
these three test cases just a minute
you create one more class suppose class
pass the cases now I want all these
three test cases not only these cases
you can write another cases also just a
minute here we have already we have the
code Nam first one just a minute
redirection first two test case
see test case one next test the case two
test just a minute pass the case to next
test the case three
okay this is our agenda continue so
inherits inherits extents methods class
name personal next create object create
object create them class name class name
is test of cases Griffith pass the cases
T should be uppercase ow yes yes yes
sensitive test the cases next suppose
obj four equal to QL two new new class
name description first the cases open
and close paren this semicolon okay next
ah just a minute first to test the case
first to test case to take that code
code already available first to test the
case which one online catalog just a
minute
this one
this is first case Oh here object change
in now OD 0 obj four okay launching of
the application next performing some
operations next closing the browser
launching browser performing operations
closing browser first perspective /
first test case / next second test case
again launching the browser just a
minute
take the second test case up to close
browser obj four URL we already used nam
so use another name or is the rename
suggestion is renamed suppose URL - URL
- ok next third test case third test
case
take that third test case obj four
in this only error message okay just a
minute I've already used arm for foreign
movies you fool
okay that for the problem ah observe it
observe pretty fast inheriting next
create object next first to test the
case first to test the case just a
minute here you can write that one test
in it this is optional test the case one
optional
next test the case one over next test
the case to test the case two
next test the case to over this is
optional
next test case three test case three
just a minute or two header says create
object not required only once create
object only once closing just a minute
first inheriting next create object next
faster test the case next second test
the case next thought test case over
okay Anna pretty yes here the statement
on the Tsarina here only creating object
once for all these three test cases
sorry
observe Audrey yes okay no Krishna
Chaitanya okay so okay try to run the
program first to redirect functionality
redirect functionality next close next
admin functionality with valid inputs
last admin functionality with the
invalid inputs a dorama if
first one redirected to user interface
past the second one past the third one
passed away not showing the test case
three this one we are not using just
terminate pass the case three this
message is optional I run the program
once again first of redirect test the
case who / second one admin login
functionality with valid inputs positive
test the case next third test the case
admin login functionality with invalid
inputs negative tester case observe
pretty test case one redirected to user
interface pass best case - admin login
successful pass test case 3 handling
invalid inputs positive okay now this is
say we can write multiple test cases in
a program now yes but observed Madhavi
that de Oscar now suppose if you are not
using these methods then how can we
write a multiple test cases browser
browser launching closing require now
yes hello yes ah on personal assignment
to you Madhavi you try the same same
program program with multiple test cases
without methods
okay now without reusable components
just a minute complete sense
Sharaman did you understand the concept
any confusion Thanks okay see next one
small concept synchronization small
concept synchronization what is
synchronization and just a minute
synchronization here topics first one
what is synchronization next why
synchronization what is synchronization
why synchronization is required
why synchronization is required
next types of synchronization types of
synchronization next examples
okay I have any idea of Madhavi
what is synchronization general
definition it is global concept you can
find synchronization feature in computer
environment programming languages in
databases for Oracle also and in
software testing also what is
synchronization matching the speeds of
two things matching the speeds of two
things just a minute general say you can
find this synchronization feature in
software development means programming
languages Java etc next in databases for
a collects ATRA in software testing test
automation you take any two lis of TR
selenium synchronization is their first
general definition it is a process of
coordinating or matching two or more
activities or devices or processes in
time C process of process of
coordinating process of coordinating our
matching not only to two or more two or
more activities activities or devices
our processes
processes in time this is general
definition next in test automation local
local definition test automation say
process of matching the speeds of a UT
UT stands for application under test
under test attune in order to get proper
execution here two things one is
application under test another is
testitude C process of matching matching
the speeds of our matching of tau T T
stands for application real time term
application under testing under test
tool selenium re of T or any other tool
test tool in order to get proper
execution in order to get proper
execution say tested tool actually no
issues with test tool issues with aut
only that I will explain before that
synchronization nowadays it is
independent topic but actually
synchronization is part of error
handling in order to avoid some type of
errors during execution we use sync
actually it is part of error-handling
but nowadays it is independent topic see
I think Alice is familiar with what is
synchronization next why synchronization
is required say up to now we created so
many test cases and executed but we
didn't concentrate on the
synchronization meaning synchronization
is only required for some scenarios
where where it is required say during
test execution test Atul gives
instructions one by one with same speed
but aut takes less time for some
statements of steps execution and more
time for some steps execution in order
to keep them in sync synchronization is
required for exam the aut also why
suppose entry value into edit box
application can respond quickly click
click on a link application can respond
quickly suppose downloading process
uploading process they may take more
time here we cannot blame the
application also observe during test
execution during test execution during
test execution or test Atul test Atul
gives instructions instructions one by
one with same speed but aut takes a
it takes less time less time for some
steps execution execution and more time
for some steps execution more time for
some steps execution in order to keep
them in sync synchronization is required
in order to keep them in sync
then synchronization is required
krishna chaitanya can you tell me where
it is required exactly up to navi
created and executed so many test cases
some steps are some steps took us less
time some success steps took more time
but we didn't face any synchronization
problem page loading page loading ok
when synchronization is required what
why when then i will explain how what
why when how i think all of you familiar
with what and why when when it is
required madhuri then it is required
saya sadhna modeling when
synchronization is required to match the
speeds of application under test and
then okay um - now we created so many
test cases and executed we didn't face
that problem now sometimes we used red
dot sweet sometimes i use only for
observation
actually they are not required
say synchronization we use that red dot
split wait time not only for
synchronizing you of sorry not only for
synchronizing aut and the tester tool in
order to observe the test execution
process you can use the trait statement
isn't it yes suppose after entering
username and password I want to observe
the data data is entering or not for
that you can write that rate statement
that is only for observation that is a
secondary usage primary you CAG
synchronization
the country uses his observation aa raha
Mon have any idea yes sir I have some
ideas Aramis over to grab some value
from the database okay you are telling
you are telling me the scenarios when it
is required in a time limitation or any
other things during education foreign I
don't know miss see actually tool can
wait default synchronisation time 20
seconds selenium can wait maximum 20
seconds for every statement
suppose if statement takes 4 seconds
then it will go to next statement
immediately next statement one second it
will go to neck
immediately suppose 19 seconds it can
wait 19 seconds after 19 seconds it will
go to another statement next statement
suppose next statement requires 24
seconds after 20 seconds it will show a
lab no such element or any error getting
this point some limit is there now when
synchronization is required whenever any
statement are step ahead takes more than
20 seconds for execution their
synchronization is required getting this
point Krishna Chaitanya
so tell me just a minute I tell me when
synchronization is required some some
steps may take more than 20 seconds for
execution say default tool default
synchronization time is 20 seconds if
any step takes more than 20 seconds for
execution their synchronization is
required isn't it
next pretty what is synchronization test
automation point of view definition
forget about general definition what is
synchronization that is the process of
matching the speeds of aut
ah in test tool in order in order to get
proper execution that is Tasha I mean
why synchronization because during this
execution
some to execute some instruction to take
more time not to take takes more time to
load take more time observance again
yeah so loading test execution pester
tool QC instructions every step is one
instruction every statement is one
instruction step statement instruction
all these are synonyms during test
execution
testitude gives instructions one by one
with the same speed no issues with test
tool but a u-2 takes less time for some
statements execution and more time for
some steps execution in order to keep
them in sync synchronization is required
okay now you see any confusion okay next
types of synchronization types of
synchronization we have two types of
synchronization one is unconditional
synchronization unconditional
synchronization
what is unconditional next conditional
synchronization what is unconditional
synchronization in this we specify
timeout value we will make the tool to
wait certain amount of time and then
proceed no condition you wait 10 seconds
or 20 seconds after the time after the
specified time proceed see in this we
specify we specify timeout value timeout
value we will make the tool to wait we
will make will make the tool to wait
certain amount of time certain amount of
time and then proceed
next syntax already we used can I
remember Krishna Chaitanya
we already indirectly that unconditional
synchronization what is that one thread
dots a thread a thread dot sleep time in
milliseconds yes time in milliseconds
say thousand milliseconds equal to one
second example I will show test example
also gesture thread dot sleep of
semicolon 9000 millisecond means nine
seconds it rates blindly next
unconditional conditional first
unconditional unconditional
synchronization next conditional
synchronization conditional
synchronization save some limitations
for this conditional synchronization it
will not work for all commands or
statements in the application it's only
work for find element and find element
statements before find element and find
element statements see limitations it
will not work for it will not work for
but unconditional synchronization will
work for all statements any statement it
will not work for all commands or
statements in the application it works
only for find element it works only for
find element and find elements find
elements statements next syntax
observable difference unconditional
synchronization blindly weights the
specified time suppose on web page is
loading I want to wait up to that web
page get loaded suppose I used
unconditional synchronization 15 seconds
but within six seconds or seven seconds
page loaded but it waits maximum 15
seconds after 15 seconds only it will go
to next statement
even though application loaded if it is
conditional synchronization it waits up
to the task performed suppose page
loaded within secret within six seconds
it won't wait maximum time conditional
synchronization won't wait maximum time
it waits a required time only suppose we
use the 15 seconds suppose within 10
seconds page loaded after 10 seconds it
will go to next step II immediately
suppose next time 14 seconds after 14
seconds it will go to next statement
suppose third iteration seven seconds
after seven seconds it will go to next
statement immediately but if it is
unconditional synchronization it waits
maximum time that specified time blindly
did observe the this point civilly
difference between unconditional
synchronization and conditional
synchronization yes
what is the difference for unconditional
year it we wait behind you a whatever
the max time we mentioned in the
statement okay
next conditional synchronization it we
take I mean a whenever the required
only it takes ten wide time only within
specified time suppose we specify 20
seconds required time 25 seconds it
won't wait 25 seconds
yes required time within the within
maximum time specified time only but it
it won't wait unnecessarily see syntax
driver dot manage driver dot manage dot
timeouts dot implicitly wait
implicitly
wait next time in seconds time in
seconds next time unit time unit dot
seconds semicolon sale so small example
suppose large Google homepage and click
Gmail link first create driver web
driver driver equal to new Firefox
driver just a minute import
Nash driver dot get Nash you are a
driver dot get google.com next after
launching the Google homepage I want to
click on Gmail link driver dot find
element by dot link text link text value
gmail dot click suppose this is our test
here no synchronization problem just
assume this page loading is taking more
time the time it is providing immediate
instructions email click and throwing
error Gmail link not available why page
still loading the time how to handle
this situation say in this scenario no
synchronization problem just assume if
synchronization problem is there then
how to handle first unconditional
synchronization thread dot sleep
suppose 10,000 milliseconds she throws
declaration then what will happen it
weights maximum ten seconds
even though application loaded suppose
application takes nine seconds it waits
nine seconds after nine seconds also it
wait 10 seconds blindly within 10
seconds if Google homepage available
then it will click suppose within 10
seconds not egg not loaded then it will
show error only anyhow it it waits 10
seconds blindly from the program see
10 seconds after 10 seconds only it will
click gmail means it will go to next
statement
ok next just a minute
suppose instead of this one if we use
this is unconditional unconditional
synchronization next conditional
conditional synchronization a remove
tell me to Sharaman
conditional synchronization I want to
specify 10 seconds conditional
synchronization this time
Dravid managed driver driver dot manage
ah dot timeout ah dot dot he physically
weight implicitly wait suppose 10
seconds are here time unit time unit dot
seconds semicolon semicolon just a
minute
this I don't use brackets ma
unconditional okay ah next C only if I
execute this script what will happen
will it wait ten seconds after Google
homepage launch are no sir
most it wait what are the required
required he have no required of
immediately loading so it will click
Gmail link immediately if required it
can wait it conveyed say
immediately over okay this is about
synchronization we will meet tomorrow
same time an Aquarius Ramon don't do it
thank you
welcome pretty maybe this is not a
relevant question but I want to ask you
some of the applications they are having
some kind of images they are
continuously moving right so those kind
of scenario and so we are going to
govern somewhere say observe selenium
has some limitations
first of all image testing in case of
image testing selenium has so many
limitations that I will send say for
image based testing selenium won't
support under selenium supports for
limited scenarios only okay now for
limited scenarios not for all scenarios
okay and how I will try to find out that
one but U of T formerly qtp q TV
supports image based testing but
selenium has limitations Krishna
Chaitanya and Goodson okay we'll meet
tomorrow same time thing
part three see today we are going to
discuss writing selenium webdriver test
cases using user-defined methods or you
can say reusable components say writing
selenium webdriver selenium webdriver
test cases using user-defined methods
yowser yowser definite methods or you
can say reusable components reusable
components okay
first create user-defined methods create
user-defined methods say if we find more
reusable components in our project we
can reduce the project code size and
complexity we can reduce the project
code size so you try to find more
reusable components okay today I will
explain how to create user-defined
methods and how to use them in test
cases first you know how to create
user-defined methods see new
class class name suppose methods
you
okay now create user-defined method for
login functionality admin login
functionality
srivalli method definition before main
method na yes
before main measure ah create
user-defined method for login
functionality you know that login
functionality we have to send a username
and password okay say public static
static not required void suppose method
name admin login okay first I am
creating without arguments then you can
create with arguments also next creates
AB driver that web driver driver equal
to new oh good new Firefox train new
Firefox driver import import web driver
import Firefox driver next I'll launch
the tip admin homepage driver dot get
get or take that URL just a minute
belled admin
next enter a username saying this method
no arguments no arguments we have to use
constant values fixed values dot find
element by dot name username username
dot Zod Keys send Keys admin next same
password edit box only by dot name
password send Keys admin at one two
three next driver dot find element by
dot ID ID of TD beavin PDB 1 dot dot
click operation click just terminated we
check that element locators user name
name locator user name next password
name locator password next login button
ID locator pdb one ok next create one
more function this time with the ok you
just call this function just a call in
this function no verification point just
to play navigation call the function you
know how to call first parade out they
ask me
chaos name class name was to create
object you
the object you can access methods
methods suppose obj equal to new methods
good new methods just a minute
new methods semi-official on matched obj
dot only here dot admin login just run
Oh disable this antivirus it is showing
another element or run the program once
again
acute Inge here no verification point
okay next right one more statement in
this test a statement is driver dot
close driver dot no close method first
of all error okay
why say we created webdriver means we
create a sorry we created driver object
in this method this is local isn't it
yes sir we created driver object in this
method a block of code it is local make
it as global make it as global before
this method public public static
webdriver webdriver equal to web driver
driver equal to in Firefox new Firefox
driver new Firefox driver semicolon now
you remove the statement you can just
use driver run the program
now it is working now this extra
statement yes sir okay next create same
admin login method with arguments its
same name admin login suppose your
surname password say whenever you are
string string data type string username
string password whenever you want to
perform login with constant values you
call first method whenever you want to
use different inputs you call second
admin login method see methods with same
name Madhuri methods with same name in
the same class this concept is called
method overloading method overloading
say next if I want to call that one just
a minute
first I am calling that method after
that closing obj dot admin admin login
username admin comma password admin at 1
2 3
semicolon change the values in find
payment forum there are static values in
the headed yes have to change we need to
username is replace the constant values
with parameters replace constant values
with parameters username password don't
use double quotes for parameters next
try to run the program
era observe civil leader while Mikasa
here we are running the same already it
used first method no no that is it Ryoga
you can you can call a number of times
that is not the issue
we need the author's rights cooler okay
after Queen Malaga's we closer to the
browser log of not required that
webdriver launches fresh instance of the
application that is not the issue here
issue is we closed the browser now after
first method next what it is showing
error communicating with the remote
browser it may have died it is ended
okay yes ah here you write one method
for a closed browser also close browser
first set by existence of browser if
they exist then close if you exist then
close okay
public void comes close browser close
browser blank parent is no arguments
next here I am writing one condition
observe the condition if not not
exploratory symbol driver driver dot -
string dot contains contains null if it
is not null then close otherwise don't
driver dot closed instead of that one
you call that function obj dot closed
browser or try to run this program
still error okay
okay for launching browser also to write
the function for launching browser just
a minute how to write a function for
launching browser rahman write function
for loop launch application also like
our launch browser also okay public just
terminate launch browser just a minute
public static just terminate launch
browser launch browser this one admin
login
without parameters next admin loggin
just a minute admin login with
parameters with parameters next close
browser okay so you remove the statement
just a public static web driver driver
semicolon just we are declaring driver
next public void suppose
launch launch browser a launch browser
just a minute mother we tell me the
statement how to launch the browser we
declared web driver as static oh yes
driver no need to write web driver
we already declared driver equal equal
to yes new Firefox driver new Firefox
driver
okay now observe I only run the program
main method nullpointerexception
it did not call yawns oh oh good good
we didn't call that one obj dot launch
application launch browser first launch
bros um first you remove the statement
where our web browser statement not
available
okay okay first launch browser admin
login close browser launch login close
again launch obj dot launch browser
admin admin login with parameters
next close
okay run the program
first first iteration of our second
iteration okay now see only executing
now yes yes sir okay say for launch
browser also we need to write the
separate method see here you can create
a n number of user-defined methods just
terminate
creating user-defined methods next
create one more class suppose class test
the case one test case one suppose in
this in this case login admin login
verification I want verification say
admin otherwise for new tested redirect
redirect to user interface redirect to
user interface from admin interface from
admin interface see this is the test
case
okay next for redirecting first login
then redirect to user interface see
manual operation admin admin at 1 2 3
next click online catalog link online
catalog link are redirecting to user
interface you take this URL ok
ah write test case login login steps
available in that a login method 3 are
civilly yes sir we have to work impaired
object now edit I inherit inherited
chaos what is the key word foreigner in
here inheritance inherits mmm keyword
for inheritance extends attendance yeah
extends class name it measures ok
next create object was to create object
or you can say instance ah class name
what is the class name that's the case
one ah next object name suppose an
object equal to new it is also new class
name same class test the case one open
and close parenthesis and a semicolon
okay next ah
verification point first you write the
steps for a verification point first a V
director user interface and verify
before that you call a required methods
whoa GG r dot a yawns frozen launch
browser required type L select launch
browser okay next object dot admin yogin
admin logon object dot admin login see
here to admin logins available you can
use without arguments are with arguments
suppose with the arguments admin admin
at one two three okay admin at one two
three the first one also we accept both
ah next so the argument are without
argument what is difference in say
suppose with arguments with arguments
you can change the value now you can use
positive values or negative values for
this test case okay suppose if it is
fixed values you cannot change not yes
say observe suppose I want to conduct
admin login functionality verification
if we use a without I if it is without
arguments you can't use you can't change
the parameters now yes ok here we are
using valid inputs for login admin
functionality this method okay suppose I
want to check error message
functionality means invalid inputs
negative testing for that this method is
not suitable not yes
suppose if we use arguments what will
happen the
method can be used for positive testing
or negative testing both isn't it yes
find the difference between a method
with arguments method without arguments
what is the difference with arguments it
will be the fixed value we can't
transition we can't change the values
that that method can be used for
positive testing only if we use
arguments that that can be used for
positive and negative testing isn't it
yes ok Nanji are continuously only
driver dot next remaining statements
where we are just back-cast
onion online catalog this is linked
eggnog online catalog ok driver observe
in this test in this program I am not
creating the driver driver created in
main class this is subclass you are
inheriting the methods and variables we
are inheriting the class members
non-static class members driver dot cyma
and element by not linked extending
suppose link test value online catalog
catalog catalog operation click link
click next after a click then capture
captured I you are a string driver or a
stream you are with URL equal to driver
dot on driver driver dot
get current your get current URL
semicolon next right collision if you
are a quite equals URL dot dot a just a
minute
dot equals what is that value we already
captured that value okay next you can
write any meaningful message suppose sys
hope control space enter redirect Ana
redirected to user interface are we
directed to user interface user
interface pastas next else not read not
redirected to user interface user
interface file okay next after this
curly brace close the browser object
object dot kills close browser
ah observe pretty in this test case we
are using reusable components nothing
but user-defined methods na yes see
first we called one method next one
method net
we write normal statements and again
method see first first one first
statement method law statement method
middle some statements this test case
specific statements see first method
second one also method next normal
statements next last one again method
Rhonda Rhonda test case
of Kamala Kamala is there I think not
available
okay next and Krishna chaser now guide
me second best case just a minute I will
copy this one this is first test case
next my second test case using
user-defined methods login functionality
admin login yesterday we did that you
know the logic admin login functionality
just eminent admin login functionality
with valid inputs with valid inputs next
as the case admin login functionality
admin login functionality with invalid
inputs invalid inputs next test the case
of Jarama 3 the day you asked now can we
write multiple test cases in a program
yes we can write it with the help of
test ng you can write multiple test
cases in a program without without
testing gr j-unit framework also you can
write multiple test cases in a program
say
right multiple multiple test cases all
these three are redirect to user
interface admin functionality with valid
inputs admin login functionality with
invalid inputs all these three test
cases in single program write multiple
test cases in a program okay next guide
me pretty I want to the second one
srivalli gated me for first test case
redirect to user interface from admin
you have to get me for the second test
case admin login functionality with
valid inputs means check that admin
login create contest okay new new class
create new Java class pretty is next
what is the test case what is the test
case admin login functionality with
valid inputs positive test case here we
are not going to check invalid inputs
positive test the case see if it is
working for valid inputs or not what
about handling invalid inputs that is
another concern another scenario ah let
me first of a step we have to launch the
browser so we have to call the method
first fastest
up we are going to access user-defined
methods are reusable components from
another class first he inherit and yeah
it exchange extents or the class name
mid methods ok inherited next next step
create object object or you can say
instance of the class create object in
this class pretty quick here create
object in the sphere in this class
obj what is the syntax class name object
name equal to new class I know that it
is kiss to s the case to this is the
class name next object name your wound
you can use any name meaningful name
suppose obj two is equal to new tsk is
to new test case to new test case to
open and close preparin this semicolon
okay object Krishna over next observe
the requires a test steps for our login
functionality firstly you need it launch
the browser then large after login
captured the URL and compare with
expected okay login login test and all
that is there a login method already
there you call that login method next
for launch application also called
method first launch application Oh DJ to
blood type level one browser
okay next obj2 obj to dot admin login
admin loggin I am using just without
arguments with arguments also you can
use and you can pass parameters see
anyhow we used valid inputs now that is
why I am calling that one next
right normal steps after login you need
to capture you are in moral strength
think you are an URL equal 200 BG no no
driver driver not getting an enquiry
okay say we are accessing driver object
from main class parent class
this is sub class in this class we did
create the driver we are accessing
driver object from main class next write
the condition if you have a URL dot
contents for example you take that one
URL this is one
contains this one then you can write
meaningful message say sys for control
space enter next admin admin login is
successful successful status of results
for example positive else failed it
unsuccessful failed next after this
verification point close the browser
resident driver dot closed otherwise we
have method na ya obg to do not close
browser okay she observed in this test
case first first two steps of methods
calling next remaining steps except law
step normal steps next last step again
method calling method call the statement
is method call
okay run the program
observe the output breathing yes
admin login successful pass faster okay
next negative test case Madhuri just a
minute just a minute who is asking
Krishna Chaitanya yes tell me Krishna
Chaitanya is there other possibility
without checking that only the URL yes
other possibility is also there you can
use say verification points you can
consider different things
observe your log of link is there none
he says after login you can get logoff
link before large in know log off link
by checking the existence of log off
link you can confirm login functionality
isn't it
not only is oral see by clicking the
exit existence of log of link you can
you can confirm the login functionality
for that you need to write the exception
also checking object object existence
now exception required if it is URL URL
is fix it now yes that is why I am
taking easiest way you can use another
another ways also no issue you can write
your observed you take you take this one
as assignment personal assignment you
write verification point for login
functionality here you consider
verification check the existence of log
of link and confirm login here exception
also required now
suppose sometimes it it will show no
such element exception if login is not
successful not enough people had
successful forget about that one suppose
successful but logoff link not available
logout another name is available for
example safe side exception required now
we already used exception handling no
such element I think yesterday day
before yesterday day before this or day
before yesterday you using that syntax
you can write ok now ok observe good
question observe or verification points
there are no fixed ways you can consider
several things but select best method
here I am taking URL why URL is fix it
URL is fixative that is why I am taking
URL otherwise you can check the object
existence suppose log of link log of
link here observe before login before
login what is the link link login link
after login after login another link
another link what is that link index
page observe Krishna Chaitanya now index
page na instead say sometimes you can
consider page title also but in this
application page title duplicate absorb
here what is the page title GC Asha
admin are just a minute
what is the page
title for beef before logon page
Jessie oh sure admin same are different
that same same did you observe the
Santos are Amin did observe before login
page title is these are shop admin after
loggin also same page title so we cannot
consider page title for verification
suppose if page titles are changing
means unique page titles then you can
use that one also okay let's come to
Main Street ah
so can you open that term which one is
Edition application ah just a minute
ah tell me sir on the top it is
mentioned GCI shop that is that is that
is rain is it that is not the page title
that is only external image just a
minute abs or tooltip what is that run
GCR shop admin otherwise just a minute
place most point on the page and right
click view page source control F here
enter title page title
just a minute so many titles are here
observe a guru pretty what is the title
of the page title attribute ya GC
Arshavin that is the page title external
you is different internal value is
important
okay now yes say second one next test
case mother he gave me I'd been logging
functionality with it invalid inputs
negative test the case positive test
case over I am creating one more class
new class perspective that's the case or
two or three three now guide me from
scratch my requirement is this one
negative test case admin login admin
login functionality with invalid inputs
negative as a case first inherit aa
extents extents methods methods that
class name parent class name next create
object our instance
ah - Turkish three just a minute
pass the case three uh any name suppose
for identification purpose I am changing
object name different object names
suppose in test case to object to test
case three object three okay equal to
new test case three new test case three
open and close power on this semicolon
next yes object three dot launch browser
type L and select launch browser next C
object 3 dot admin login with parameters
observe pretty you ask Anna for this
negative test case with parameters only
is without if you call without
parameters in that we use a constant
values those are valid input isn't it
yes it is a admin for example invalid
input admin but actual user name is just
admin I am using incorrect username next
admin at one two three a password also
incorrect okay next
Archer the string nah what is that one
error message after invalid input you
can get error message now what is that
error message
this one from write that statement for
that one
just a minute
string you suppose error message equal
to sorry driver dot find element by dot
y dot just a minute here you can use
class message stack error message stay
care of just a minute by dot class name
class name locator value just a minute
. ah get this get it is not taking class
name any error by by dot class name okay
import by oh oh yes yes get texted okay
next here one condition required ah for
advancing we have to input yes by also
built in class what I'm asking it is not
we never did before right
see earlier sometimes it is
automatically imports just a minute
where is the trum method so you can
check
here in this main class by already
imported okay by is built in Class C
here open key a selenium by yeah okay a
continuum of a string error message okay
next we write the condition right
condition ah
tell me the condition if ah yes error
message error message dot equals dot con
tiles in this select this total one next
what is a problem ah right message
suppose control space enter handling
invalid inputs invalid inputs positive
next else not handling say ah not
handling
invalid inputs valid next after this
condition close browser dot close
browser run the program
but
say handling invalid inputs past next
rom on multiple test cases in a program
yes sir on you write a program for all
these three test cases just a minute
you create one more class suppose class
pass the cases now I want all these
three test cases not only these cases
you can write another cases also just a
minute here we have already we have the
code Nam first one just a minute
redirection first two test case
see test case one next test the case two
test just a minute pass the case to next
test the case three
okay this is our agenda continue so
inherits inherits extents methods class
name personal next create object create
object create them class name class name
is test of cases Griffith pass the cases
T should be uppercase ow yes yes yes
sensitive test the cases next suppose
obj four equal to QL two new new class
name description first the cases open
and close paren this semicolon okay next
ah just a minute first to test the case
first to test case to take that code
code already available first to test the
case which one online catalog just a
minute
this one
this is first case Oh here object change
in now OD 0 obj four okay launching of
the application next performing some
operations next closing the browser
launching browser performing operations
closing browser first perspective /
first test case / next second test case
again launching the browser just a
minute
take the second test case up to close
browser obj four URL we already used nam
so use another name or is the rename
suggestion is renamed suppose URL - URL
- ok next third test case third test
case
take that third test case obj four
in this only error message okay just a
minute I've already used arm for foreign
movies you fool
okay that for the problem ah observe it
observe pretty fast inheriting next
create object next first to test the
case first to test the case just a
minute here you can write that one test
in it this is optional test the case one
optional
next test the case one over next test
the case to test the case two
next test the case to over this is
optional
next test case three test case three
just a minute or two header says create
object not required only once create
object only once closing just a minute
first inheriting next create object next
faster test the case next second test
the case next thought test case over
okay Anna pretty yes here the statement
on the Tsarina here only creating object
once for all these three test cases
sorry
observe Audrey yes okay no Krishna
Chaitanya okay so okay try to run the
program first to redirect functionality
redirect functionality next close next
admin functionality with valid inputs
last admin functionality with the
invalid inputs a dorama if
first one redirected to user interface
past the second one past the third one
passed away not showing the test case
three this one we are not using just
terminate pass the case three this
message is optional I run the program
once again first of redirect test the
case who / second one admin login
functionality with valid inputs positive
test the case next third test the case
admin login functionality with invalid
inputs negative tester case observe
pretty test case one redirected to user
interface pass best case - admin login
successful pass test case 3 handling
invalid inputs positive okay now this is
say we can write multiple test cases in
a program now yes but observed Madhavi
that de Oscar now suppose if you are not
using these methods then how can we
write a multiple test cases browser
browser launching closing require now
yes hello yes ah on personal assignment
to you Madhavi you try the same same
program program with multiple test cases
without methods
okay now without reusable components
just a minute complete sense
Sharaman did you understand the concept
any confusion Thanks okay see next one
small concept synchronization small
concept synchronization what is
synchronization and just a minute
synchronization here topics first one
what is synchronization next why
synchronization what is synchronization
why synchronization is required
why synchronization is required
next types of synchronization types of
synchronization next examples
okay I have any idea of Madhavi
what is synchronization general
definition it is global concept you can
find synchronization feature in computer
environment programming languages in
databases for Oracle also and in
software testing also what is
synchronization matching the speeds of
two things matching the speeds of two
things just a minute general say you can
find this synchronization feature in
software development means programming
languages Java etc next in databases for
a collects ATRA in software testing test
automation you take any two lis of TR
selenium synchronization is their first
general definition it is a process of
coordinating or matching two or more
activities or devices or processes in
time C process of process of
coordinating process of coordinating our
matching not only to two or more two or
more activities activities or devices
our processes
processes in time this is general
definition next in test automation local
local definition test automation say
process of matching the speeds of a UT
UT stands for application under test
under test attune in order to get proper
execution here two things one is
application under test another is
testitude C process of matching matching
the speeds of our matching of tau T T
stands for application real time term
application under testing under test
tool selenium re of T or any other tool
test tool in order to get proper
execution in order to get proper
execution say tested tool actually no
issues with test tool issues with aut
only that I will explain before that
synchronization nowadays it is
independent topic but actually
synchronization is part of error
handling in order to avoid some type of
errors during execution we use sync
actually it is part of error-handling
but nowadays it is independent topic see
I think Alice is familiar with what is
synchronization next why synchronization
is required say up to now we created so
many test cases and executed but we
didn't concentrate on the
synchronization meaning synchronization
is only required for some scenarios
where where it is required say during
test execution test Atul gives
instructions one by one with same speed
but aut takes less time for some
statements of steps execution and more
time for some steps execution in order
to keep them in sync synchronization is
required for exam the aut also why
suppose entry value into edit box
application can respond quickly click
click on a link application can respond
quickly suppose downloading process
uploading process they may take more
time here we cannot blame the
application also observe during test
execution during test execution during
test execution or test Atul test Atul
gives instructions instructions one by
one with same speed but aut takes a
it takes less time less time for some
steps execution execution and more time
for some steps execution more time for
some steps execution in order to keep
them in sync synchronization is required
in order to keep them in sync
then synchronization is required
krishna chaitanya can you tell me where
it is required exactly up to navi
created and executed so many test cases
some steps are some steps took us less
time some success steps took more time
but we didn't face any synchronization
problem page loading page loading ok
when synchronization is required what
why when then i will explain how what
why when how i think all of you familiar
with what and why when when it is
required madhuri then it is required
saya sadhna modeling when
synchronization is required to match the
speeds of application under test and
then okay um - now we created so many
test cases and executed we didn't face
that problem now sometimes we used red
dot sweet sometimes i use only for
observation
actually they are not required
say synchronization we use that red dot
split wait time not only for
synchronizing you of sorry not only for
synchronizing aut and the tester tool in
order to observe the test execution
process you can use the trait statement
isn't it yes suppose after entering
username and password I want to observe
the data data is entering or not for
that you can write that rate statement
that is only for observation that is a
secondary usage primary you CAG
synchronization
the country uses his observation aa raha
Mon have any idea yes sir I have some
ideas Aramis over to grab some value
from the database okay you are telling
you are telling me the scenarios when it
is required in a time limitation or any
other things during education foreign I
don't know miss see actually tool can
wait default synchronisation time 20
seconds selenium can wait maximum 20
seconds for every statement
suppose if statement takes 4 seconds
then it will go to next statement
immediately next statement one second it
will go to neck
immediately suppose 19 seconds it can
wait 19 seconds after 19 seconds it will
go to another statement next statement
suppose next statement requires 24
seconds after 20 seconds it will show a
lab no such element or any error getting
this point some limit is there now when
synchronization is required whenever any
statement are step ahead takes more than
20 seconds for execution their
synchronization is required getting this
point Krishna Chaitanya
so tell me just a minute I tell me when
synchronization is required some some
steps may take more than 20 seconds for
execution say default tool default
synchronization time is 20 seconds if
any step takes more than 20 seconds for
execution their synchronization is
required isn't it
next pretty what is synchronization test
automation point of view definition
forget about general definition what is
synchronization that is the process of
matching the speeds of aut
ah in test tool in order in order to get
proper execution that is Tasha I mean
why synchronization because during this
execution
some to execute some instruction to take
more time not to take takes more time to
load take more time observance again
yeah so loading test execution pester
tool QC instructions every step is one
instruction every statement is one
instruction step statement instruction
all these are synonyms during test
execution
testitude gives instructions one by one
with the same speed no issues with test
tool but a u-2 takes less time for some
statements execution and more time for
some steps execution in order to keep
them in sync synchronization is required
okay now you see any confusion okay next
types of synchronization types of
synchronization we have two types of
synchronization one is unconditional
synchronization unconditional
synchronization
what is unconditional next conditional
synchronization what is unconditional
synchronization in this we specify
timeout value we will make the tool to
wait certain amount of time and then
proceed no condition you wait 10 seconds
or 20 seconds after the time after the
specified time proceed see in this we
specify we specify timeout value timeout
value we will make the tool to wait we
will make will make the tool to wait
certain amount of time certain amount of
time and then proceed
next syntax already we used can I
remember Krishna Chaitanya
we already indirectly that unconditional
synchronization what is that one thread
dots a thread a thread dot sleep time in
milliseconds yes time in milliseconds
say thousand milliseconds equal to one
second example I will show test example
also gesture thread dot sleep of
semicolon 9000 millisecond means nine
seconds it rates blindly next
unconditional conditional first
unconditional unconditional
synchronization next conditional
synchronization conditional
synchronization save some limitations
for this conditional synchronization it
will not work for all commands or
statements in the application it's only
work for find element and find element
statements before find element and find
element statements see limitations it
will not work for it will not work for
but unconditional synchronization will
work for all statements any statement it
will not work for all commands or
statements in the application it works
only for find element it works only for
find element and find elements find
elements statements next syntax
observable difference unconditional
synchronization blindly weights the
specified time suppose on web page is
loading I want to wait up to that web
page get loaded suppose I used
unconditional synchronization 15 seconds
but within six seconds or seven seconds
page loaded but it waits maximum 15
seconds after 15 seconds only it will go
to next statement
even though application loaded if it is
conditional synchronization it waits up
to the task performed suppose page
loaded within secret within six seconds
it won't wait maximum time conditional
synchronization won't wait maximum time
it waits a required time only suppose we
use the 15 seconds suppose within 10
seconds page loaded after 10 seconds it
will go to next step II immediately
suppose next time 14 seconds after 14
seconds it will go to next statement
suppose third iteration seven seconds
after seven seconds it will go to next
statement immediately but if it is
unconditional synchronization it waits
maximum time that specified time blindly
did observe the this point civilly
difference between unconditional
synchronization and conditional
synchronization yes
what is the difference for unconditional
year it we wait behind you a whatever
the max time we mentioned in the
statement okay
next conditional synchronization it we
take I mean a whenever the required
only it takes ten wide time only within
specified time suppose we specify 20
seconds required time 25 seconds it
won't wait 25 seconds
yes required time within the within
maximum time specified time only but it
it won't wait unnecessarily see syntax
driver dot manage driver dot manage dot
timeouts dot implicitly wait
implicitly
wait next time in seconds time in
seconds next time unit time unit dot
seconds semicolon sale so small example
suppose large Google homepage and click
Gmail link first create driver web
driver driver equal to new Firefox
driver just a minute import
Nash driver dot get Nash you are a
driver dot get google.com next after
launching the Google homepage I want to
click on Gmail link driver dot find
element by dot link text link text value
gmail dot click suppose this is our test
here no synchronization problem just
assume this page loading is taking more
time the time it is providing immediate
instructions email click and throwing
error Gmail link not available why page
still loading the time how to handle
this situation say in this scenario no
synchronization problem just assume if
synchronization problem is there then
how to handle first unconditional
synchronization thread dot sleep
suppose 10,000 milliseconds she throws
declaration then what will happen it
weights maximum ten seconds
even though application loaded suppose
application takes nine seconds it waits
nine seconds after nine seconds also it
wait 10 seconds blindly within 10
seconds if Google homepage available
then it will click suppose within 10
seconds not egg not loaded then it will
show error only anyhow it it waits 10
seconds blindly from the program see
10 seconds after 10 seconds only it will
click gmail means it will go to next
statement
ok next just a minute
suppose instead of this one if we use
this is unconditional unconditional
synchronization next conditional
conditional synchronization a remove
tell me to Sharaman
conditional synchronization I want to
specify 10 seconds conditional
synchronization this time
Dravid managed driver driver dot manage
ah dot timeout ah dot dot he physically
weight implicitly wait suppose 10
seconds are here time unit time unit dot
seconds semicolon semicolon just a
minute
this I don't use brackets ma
unconditional okay ah next C only if I
execute this script what will happen
will it wait ten seconds after Google
homepage launch are no sir
most it wait what are the required
required he have no required of
immediately loading so it will click
Gmail link immediately if required it
can wait it conveyed say
immediately over okay this is about
synchronization we will meet tomorrow
same time an Aquarius Ramon don't do it
thank you
welcome pretty maybe this is not a
relevant question but I want to ask you
some of the applications they are having
some kind of images they are
continuously moving right so those kind
of scenario and so we are going to
govern somewhere say observe selenium
has some limitations
first of all image testing in case of
image testing selenium has so many
limitations that I will send say for
image based testing selenium won't
support under selenium supports for
limited scenarios only okay now for
limited scenarios not for all scenarios
okay and how I will try to find out that
one but U of T formerly qtp q TV
supports image based testing but
selenium has limitations Krishna
Chaitanya and Goodson okay we'll meet
tomorrow same time thing
