Headless browser testing is a method of running automated tests without a graphical user interface (GUI). In Selenium, headless browsers like Chrome, Firefox, and PhantomJS allow tests to execute faster by eliminating the need to render visual elements. This improves performance, reduces resource consumption, and enhances CI/CD integration. Professionals looking to master automation testing can benefit from a Selenium certification online course, which covers headless testing techniques. Key advantages include faster execution, improved efficiency, and the ability to run tests in the background, making it an essential approach for large-scale test automation in Agile and DevOps environments.
