Cross Browser Testing – Firefox, IE, Chrome, Edge

What is Cross-Browser Testing?

Cross-browser testing verifies that a web application works correctly across different browsers, since rendering and JavaScript behavior can vary between them.

Setting Up Different Drivers

WebDriver driver = new ChromeDriver();   // Chrome
WebDriver driver = new FirefoxDriver();  // Firefox
WebDriver driver = new EdgeDriver();     // Edge

Common Approach

Automation frameworks often parameterize the browser choice (e.g., via a config file or TestNG parameter), letting the same test suite run against multiple browsers without duplicating test code.
