Advantages: Multi-browser support (Chrome, Safari, Edge, Firefox), Multi-OS support (Windows, Mac, Linux), Open source and free, Large community, Easy integration with CI/CD pipelines, Supports all programming languages. Limitations: No built-in reporting (requires TestNG/ExtentReports), Struggles with Captcha/Barcodes (by design), Cannot handle Windows file upload dialogs natively, No support for desktop applications, Cannot interact with elements outside the browser DOM.
Advantages: You write once, run everywhere. Limitations: Selenium can't deal with security features like Captcha because Captcha is designed to stop bots.
Your test script needs to upload a profile picture, but when you click 'Upload', a Windows File Explorer window opens. Selenium stops working. Why, and how do you fix it?
