Selenium is an open-source automation testing framework used to validate web applications across different browsers and platforms. It enables testers and developers to automate the testing process by simulating user interactions with web browsers and verifying the expected behavior of web applications.
Features and Functionalities:
• Multiple Language Support: Selenium allows writing test scripts in various programming languages, including Java, C#, Python, and Ruby.
• Cross-Browser Compatibility: It supports testing on multiple browsers like Chrome, Firefox, Safari, and Internet Explorer.
• Parallel Test Execution: Selenium can run multiple tests in parallel, reducing the time required for test execution.
• Selenium Grid: Enables running tests on different machines and browsers simultaneously.
• Selenium IDE: A browser extension that provides a record-and-playback tool for authoring tests without learning a test scripting language.
• WebDriver: A tool for automating web application testing to simulate complex user gestures like click, scroll, drag-and-drop.
Use Cases in Software Testing and Quality Assurance:
• Functional Testing: Automating the validation of functions of web applications.
• Regression Testing: Ensuring that new code changes do not break existing functionalities.
• Cross-Browser Testing: Verifying that web applications work consistently across different web browsers.
• Continuous Integration: Integrating Selenium tests into CI/CD pipelines for continuous testing.
• Data-Driven Testing: Running tests with different sets of input data to cover more scenarios.
Selenium’s capabilities make it a key tool in modern software development and testing, ensuring that applications are robust, reliable, and deliver a consistent user experience across various platforms and devices.
