- Selenium:

1. Selenium is an open source tool that is used for automating the tests carried out on different web browsers and programming languages.

2. Selenium is a set of tools that helps tester automate web-based applications more efficiently.

3. By using Selenium, we can automate the functional tests and easily integrate them.

4. Selenium has four components: Selenium IDE, Selenium RC, Selenium Web driver, Selenium Grid.

5. Selenium have no licensing cost for its usage.

6. Selenium provides platform support for all the major operating systems, like Windows, Linux and Mac OS.

7. Selenium supports most of the popular browsers, like Chrome, Firefox, Opera and Safari.

8. Selenium has features to enable users to incorporate additional functionalities through several plugins or extensions.

-** Why Do we use Selenium for Automation:**

1. Selenium automation allows tests to be executed quickly and accurately, reducing the likelihood of human mistakes and ensuring consistent test results.

2. Selenium allows developers and testers to automate testing of web applications across different browsers and platforms.

• Selenium allows different languages to be supported.

• Selenium enables you to test your websites on different browsers.

• Automated testing with Selenium can easily scale to cover a wide range of test cases, scenarios and user interactions.

• Selenium supports parallel test executions, allowing multiple tests to run concurrently.

• Selenium provides detailed test execution logs and reports, making it easier to track test results and identify areas that require attention.

• Selenium can simulate user interactions and behavior, allowing testers to assess the user experience and ensure that the application is intuitive and user-friendly.

• _Components of Selenium:
  _

• Selenium IDE is mainly used to record user interactions, such as clicks, and selections and in browsers and play them back as automated tests.

• Selenium RC was build to automate the testing of web applications by simulating user interactions across different browsers and platforms.

• Selenium Web driver communicates with browsers directly with the help of browser-specific native methods. Mainly used for functional testing and Cross-browsers testing.

• In Future AI and Machine learning could be integrated into Selenium testing to enhance test generation, data analysis and test optimization.

• In Future Selenium testing will shift towards headless and Mobile testing. Headless browsers testing allows for faster execution and enables testing scenarios that are challenging in graphical environments.

• Selenium Web driver will likely continue expanding its supports for new browser version as well as emerging browsers and operating systems.

• In Future Security testing could become a more integral part of Selenium testing with specialized tools and libraries to automate security related tests.
