Selenium Tutorial 1: Introduction to Selenium Video Lecture | Selenium Test Automation:Tutorial for Beginners (English) - Software Testing

Ans. Selenium is an open-source software testing framework used for automating web browsers. It allows testers to write test scripts in various programming languages to interact with web applications and perform automated testing.

Ans. Selenium supports multiple programming languages such as Java, C#, Python, Ruby, and JavaScript. Testers can choose their preferred language to write test scripts based on their familiarity and project requirements.

Ans. Selenium consists of three main components: Selenium WebDriver, Selenium IDE, and Selenium Grid. WebDriver is used for automating web browsers, IDE is a record-and-playback tool for creating test cases, and Grid is used for parallel test execution across different browsers and platforms.

Ans. Selenium WebDriver works by interacting directly with the web browser using the browser's native support for automation. It sends commands to the browser through a communication channel (HTTP) and receives the results back to perform actions and validations on web elements.

Ans. Some advantages of using Selenium for software testing include: - Cross-browser compatibility: Selenium supports multiple browsers such as Chrome, Firefox, Safari, and Internet Explorer, allowing testers to ensure their application works consistently across different browsers. - Flexibility: Selenium supports multiple programming languages, making it easier for testers to use their preferred language for writing test scripts. - Open-source: Selenium is free to use and has a large community of developers contributing to its improvement, providing regular updates and support. - Parallel test execution: Selenium Grid allows testers to execute test cases in parallel on multiple browsers and platforms, reducing test execution time. - Integration with other tools: Selenium can be easily integrated with other testing frameworks and tools such as TestNG, JUnit, and Jenkins, enhancing the overall testing process.
