The Sauce Labs Extended Debugging feature allows QA engineers to gain insight into network requests that can cause automated tests to fail, helping identify application problems before shipping a new release. This feature provides direct access to browser developer tools, enabling the tracking of performance issues and code optimization opportunities, as well as debugging flaky tests and using intercept requests, throttle, and more. It offers out-of-the-box features such as custom browser extensions, manipulation, and mockup of networking requests, receiving information about network events, intercepting and blocking requests, throttling, and log types. By building a strategy around Extended Debugging, QA engineers can focus on quality checking, analytics testing, and improving test coverage, ultimately building web applications with confidence and faster.
