Selenium

Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing.

Selenium is an open-source suite of tools and libraries that is used for browser automation. Selenium us used to:

• It allows users to test their websites functionally on different browsers.?
• Perform Cross browser testing to check if the website functions consistently across different browsers.?

It provides a single interface that lets you write test scripts in programming languages like Ruby, Java, NodeJS, PHP, Perl, Python, JavaScript, and C#, among others. Selenium is very extensible and can be integrated with other tools and frameworks like TestNG, JUnit, Cucumber, etc.

Importance of Testing in Selenium

Manual testing can be time-consuming and prone to human errors. Selenium Automation allows tests to be executed quickly and accurately, reducing the likelihood of human mistakes and ensuring consistent test results.

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

1. Language Support: Selenium allows you to create test scripts in different languages like Ruby, Java, PHP, Perl, Python, JavaScript, and C#, among others.
2. Browser Support: Selenium enables you to test your website on different browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Internet Explorer (IE), etc.?
3. Scalability: Automated testing with Selenium can easily scale to cover a wide range of test cases, scenarios, and user interactions. This scalability ensures maximum test coverage of the application’s functionality.
