Selenium is a powerful open-source framework for automating web browsers. It's widely used for test automation, browser compatibility testing, and CI/CD integration. Let's dive into the basics!

📚 What is Selenium?

Selenium allows developers to write test scripts in languages like Python, Java, or C#. It supports multiple browsers (Chrome, Firefox, Edge, Safari) and provides tools for automated testing.

🔧 Key Components

  • Selenium WebDriver: Controls the browser directly.
  • Selenium IDE: A browser extension for recording and playing back tests.
  • Selenium Grid: Enables parallel execution across different machines.
  • Selenium Server: Used for running tests in a remote environment.

🧪 Getting Started with Python

  1. Install Selenium: 
    pip install selenium
  2. Download Browser Drivers:
  3. Write Your First Script: 
    from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://www.example.com")
print(driver.title)
driver.quit()

🌐 Example Use Cases

  • Test Automation: Automate repetitive test scenarios.
  • Regression Testing: Ensure changes don't break existing functionality.
  • Cross-Browser Testing: Validate behavior across different browsers.

📌 Best Practices

  • Use explicit waits instead of hardcoded delays.
  • Organize tests into test cases and test suites.
  • Leverage Page Object Model (POM) for maintainable code.
