How Selenium Testing Tool Works?
Selenium is an open-source automation testing tool used for testing web applications across different browsers. It allows testers to automate user interactions, verify functionalities, and ensure software quality.
How Selenium Works: Step-by-Step
1. Setup Selenium Environment
- Install Selenium WebDriver for browser automation.
- Choose a programming language (Java, Python, C#, etc.).
- Install a test framework (TestNG, JUnit, PyTest) for structured execution.
2. Writing Test Scripts
- Identify elements using locators (ID, Name, XPath, CSS Selector).
- Write test scripts using Selenium commands (e.g.,
click()
,sendKeys()
,getText()
). - Use assertions to validate expected vs. actual outcomes.
3. Executing Test Cases
- Run tests on different browsers (Chrome, Firefox, Edge).
- Use Selenium Grid for parallel execution.
- Capture logs and screenshots for debugging.
4. Generating Reports
- Integrate with TestNG or JUnit to generate test reports.
- Analyze test results for failures and defects.
