Browser compatibility testing is an essential part of web development. It ensures that the website or web application functions correctly across different browsers and browser versions. Automated cross-browser testing can be performed using cloud-based platforms like LambdaTest, which provides a scalable solution for executing automated Selenium tests on a range of browsers and operating systems. This approach accelerates the testing process and improves test coverage, ensuring that the website/web application’s functionalities and overall design have been thoroughly tested against different combinations of browsers and operating systems.
