UFT 12.01 | QTP | Debugging Techniques in UFT Video Lecture | Automation Training with HPE Unified Functional Testing 12.0 - Software Testing

hello everyone welcome to the video
series on EFT automation in this video
we will look at the debugging concepts
in EFT the debugging concepts comes real
handy when you have issues with your
scripts and that this is the only way to
troubleshoot the scripts and you know
this is these concepts are pretty much
same in.net programming environment in
java programming environment any other
programming environment it's in these
debugging concepts are pretty much the
same so let's start with a breakpoint
you know here I have a very simple
script it you know there are two values
here price and number of tickets and the
two numbers and I'm multiplying it using
a function library so this test is as
you know function library associated to
it let's go in there so this particular
function library which you know I
believe you all have looked at it in
another video it's it's the same
function library so you tell multiple
methods you know four methods to add
subtract divide multiply and there was
another thing here well we don't have to
worry about it it just takes a foreign
hat and converts into a Celsius so so
we're gonna use one of these functions
to multiply in numbers
let's go there go back to the script and
you know it's actually printing
something out so it'll be in the output
let me go ahead and run the script and
just to show that you know it works just
fine and then we'll we'll talk about you
know debugging concepts so well it's
working now if we don't let's say no if
it's a huge script and a huge function
library it might be hard to tell where
these values are coming from so and also
let's say I really want to know what is
being passed here I mean I know that
this is 100 point to and this is 20 you
really want to know what the value of
price this
going in so to start with that that is
exactly what I'm trying to deter mine
and so multiply that's here so that's
much whatever I pass there should be
coming here so I want to know this as
well that would be our target so in
order for us to look at those values
first thing we need to do is we need to
add a breakpoint breakpoint okay for now
let's see how we can add a breakpoint
and then we'll talk about what a
breakpoint is so here I believe you
might have seen the other video where we
were talking about debugging not
debugging I'm sorry adding bookmarks
same way you you just click on this
vertical bar and that red dot is the
breakpoint and if you go there's a
breakpoint pane and as you add
breakpoints it has things here I can
delete them
I can add them and make them inactive so
so this is the only active breakpoint
but these two are not active even though
they are marked and they're here but
they are not active they are not enabled
primarily let me remove that so let me
say this is a very first line within the
script I'm going to add a breakpoint
there meaning the execution will stop
right there line number seven let me do
that okay so the if the execution
stopped I mean this is applicable even
for you know flight reservation
application or for that matter any
script you add a breakpoint the script
stops execution right there I mean it's
before the line gets executed that's
when it stopped not after so when you
say a breakpoint is at seven if right
before the line number seven needs to be
executed that's when you are putting a
breakpoint you're stopping there
so the first option you only have this
you can just say you know continue and
it will just you know continue with the
next step and finish the whole thing but
say there is another breakpoint here so
if you run it so for number first it
will stop at number seven and at number
seven if I say continue they will start
eleven again because there's another
breakpoint that's you know one idea of
using breakpoints let's say I have these
two but I wanted to something a little
bit different I want to you know add a
breakpoint
I mean I I there's a breakpoint and I
want to go step by step rather than you
know it stops and then I continue I
don't want to do that I really want to
put a breakpoint and go step by step and
see what happens and I want to do line
by line check things up so let me run
the script so it should stop at line
number seven so let me clear all this
line number seven now instead of using
the continue you have two other things
here one is step into the other is step
over and if you look at the icon if you
pay attention to it step into it's
almost going into something whereas step
over is just you know stepping over so
if I do you know skip this for a second
here and I'll start using step over so
when I click this hit this button what
happens is now it finished line number
seven it went to line eight hit that
time well I am in that button step over
it goes to next line then goes to the
next line so it just you know when it
finished line nine that means that's
where this is coming from this print
came after executing line number nine
that means there must be something
inside there line nine inside you
remember that word inside something
inside this thing printed this line out
now I do you know step over again so
that was a very last line and it
finished and you have all this now let's
debug the you know go to the same thing
again but this time we will use step
into now step into me you know it has a
value only if there is some sort of
function or link into this whole deal
say for example here if I do
step into when there's nothing to go and
investigate there so I'm doing step into
again nothing but look at line number
nine it says that total equal to
multiply and it's passing two arguments
then what is this multiply and multiply
is one of those functions so if I do
step over then you go to line it will
finish everything it will execute the
function get the value of say total and
then go to line number 11 say instead I
want to do step into that means it needs
to go into the function multiplied by
hit that it goes into 19 I mean it's
here now if you look at a and B there
are the two values let's say I want to
know a and B but how do I know I can't
see any values here right look at here a
is 20 B is 102 sorry I mean to say 100
point - that's a double as integer so
let me keep this here local variables
local variables will display all the
values are local to that particular
activity so let me continue with that
second step out meaning it will you know
it will finish the whole thing
I mean 1918 it will finish the whole
thing and exit out of the whole function
and continue to the next slide but if I
do step into but there is no step into
here if this were to call another
function that will go you know into that
other function as well but here let's
you know continue step over and it's
gonna multiply do that that's here if I
go to local variables have price as 100
point to number of figures 28 or less
2004 and you know the thing is there
might be you know 10 20 30 40 variables
if you know within this particular
action of look at this if you don't have
a and B here because a and B are
irrelevant for this section of the
script so you only have certain
variables and those variables are here
but what if you have like 30 40
variables and you only want to kind of
watch
you know two specific variables right so
there's a way to do that so let me show
that as well I'll just hit continue let
you finish the script so this time we
will kind of twist this little bit I'm
gonna run it it's wrong of course it'll
break there what I'll do is I want to
watch scripts I can do this put an
expression that I know the actual school
you know variable or you can do price is
right click on it and say add to watch
so I'll I always want to watch the price
and then I also want to watch the total
and also want to watch the number of
scripts and the total as well and I also
want to watch a B as well
adjust the screen a little bit I mean
this would help because you know
irrespective of where you are you will
see you know because these three are
coming from this document but the
variables a and B are actually coming
from the function so if when I have this
look at this I want to do go slow I'll
step into as much as I can so step over
look at the price okay you know look at
the watch pane here it's hon hon - they
step over look at number of tickets is
20 because now the value has been a sign
I'm going to step into and now the time
it went in a step into these variables
are not you know accessible variable is
undefined because it's undefined within
the scope then I'm going to do step over
wash so you know these two values step
over step over and now again we are back
so we don't have to you know switch back
here and there so we can add values here
within the wash so it really doesn't
kind of you know show its main purpose
when you have just had
full of variables but when you when
you're dealing with you know tens of
variables you know 50 60 100 sometimes
even 200 variables then this comes real
handy because you can pick and choose
the variables that you want to watch as
the script is executing I mean to say
not even them in our right term is you
know while we're debugging it really
helps that it's done now if we go to you
know it's it's it's a debugging session
so you don't have those you know wash
it's a runtime pain so it's done so that
is how you debug and if you go to let me
start one more time quick recap
so the breakpoint will actually you know
stop the script from executing so that's
right before the step gets executed you
know the step or the execution will stop
there's one option or you know one thing
and way you add breakpoint is just
clicking here you can do while you're
running as long as it is you know it
stopped you can just you know click
there I know this stops executing and
not just here you can actually add a
breakpoint inside the function and if
you try to reckon you to run it'll stop
there because you have a breakpoint
there if you put a breakpoint out here
and if you try to run it'll come and
stop here so that's what you know you
know the thing about breakpoint and here
yeah so this is step into and this is
step over and this is not visible
you know it's disable to step out so if
you're inside some function you can exit
that you can you can complete the
execution of the function and exit out
and come back to where you know it is
being here called from so it comes real
handy when you have issues with the
scripts you really don't know what's
happening then you can really stop the
script executes line by line
take your time investigate it and see
what happening this comes real handy
when you are working with integrating
with other systems say your applications
you know integrating I'm sorry
integrated with a database and talking
to a third-party application and the
scenario includes the whole thing then
you can literally go step by step
checking the database check with the
third-party application come back check
here do you think go back check so you
can do all that it comes real handy so
and a lot of programmers for us are a
lot of QA testers for some reason they
kind of get scared getting the debugging
and experimenting and doing that so I
would highly encourage if this is making
you uncomfortable at least spend a
couple of hours start with a simple
script debug every script run record a
script debugging you call debug it
unless you're comfortable until you get
comfortable because this is one of those
things you know in real time you will be
debugging the scripts all the time so
when you interview you know if you got a
chance to talk about debugging and you
talk I mean you literally can't impress
them it adds a lot of value but make
sure you talk about how you debug how
you take advantage of step into step out
and step over and how you take advantage
of watch and local variables so that's
important I mean if you don't know how
to add a variable to watch there is no
point in debugging because that's where
the power of debugging you know comes
into play okay well and you know
practice that that's what you know helps
you okay well then that's it about you
know debugging in UFT and I will talk to
you in the next video
thank you for watching this video
