How and where is Selenium used?

Cases when Selenium does not work

1. Selenium does not work with non-web applications: Selenium is specifically designed for web applications and cannot be used to automate non-web applications such as desktop applications or mobile apps. If you need to automate non-web applications, you’ll need to explore alternative tools or frameworks specifically designed for those types of applications.
2. Elements with dynamic IDs or attributes: Selenium relies on locating elements on a webpage using various attributes like IDs, class names, or XPath. If the elements on a webpage have dynamically changing IDs or attributes, it can be difficult for Selenium to consistently locate and interact with those elements.
3. Elements within iframes: If a webpage contains iframes (inline frames), Selenium may encounter difficulties interacting with elements inside those iframes. It requires switching the focus to the iframe before locating and interacting with the elements within it.
4. Performance issues: Selenium operates by controlling web browsers, and sometimes performance issues may arise when dealing with large or complex webpages. Slow page loading times, heavy JavaScript usage, or excessive DOM manipulation can impact the responsiveness of Selenium.
5. Browser compatibility: Selenium supports multiple web browsers, but there can still be compatibility issues with certain browser versions or configurations. Updates to browsers or changes in their rendering engines may cause Selenium scripts to fail or behave unexpectedly.
6. CAPTCHA or reCAPTCHA: Selenium struggles with automating interactions involving CAPTCHA or reCAPTCHA challenges. These security measures are specifically designed to prevent automated bots, including Selenium, from bypassing them.
