Handling Alerts, Pop-ups, and Frames in Selenium WebDriver

Image
Dealing with alerts, pop-ups, and frames is super important for test automation using Selenium WebDriver. Modern websites have all sorts of alerts and frames, meaning you, as a tester, need to switch between them and deal with random pop-ups. If you can handle these things well, your tests will run smoothly and validate user actions correctly. Knowing how to manage alerts, pop-ups, and frames really helps when building solid automation setups. If you want to learn how to do this stuff and get better at automation, check out Selenium Training in Chennai – they'll give you some tips and real-world practice. 1. Types of Alerts in Selenium Alerts are those message boxes that pop up in your browser and require you to click something. Selenium deals with three kinds: Simple Alerts (just a message and an OK button), Confirmation Alerts (OK and Cancel), and Prompt Alerts (where you can type something before hitting OK). Handling these correctly means your scripts won't break because of...
