This makes them developer-friendly and can reduce flakiness through the tight browser integration, network mocking/stubbing, emulating network capabilities and resolutions, as well as delightful features such as built-in waits and test reruns. All of these frameworks are open source and each have their own pros and cons depending on your testing priorities. Sauce Labs supports all three via the saucectl CLI, and works with customers as they make decisions on the future of testing at their organizations.
Selenium is the most adopted and most robust test automation framework used today. It is also the preferred test automation framework for QA testers who run comprehensive test automation strategies, so we think it’s here to stay.
Selenium is comprehensive, complies with the W3C WebDriver standard, and is supported by the open source community. That means it offers the best test coverage and testing capabilities and remains the framework of choice for QA teams. With Selenium, you have remote testing targets, which allows you to specify exact browsers or browser versions and device combinations on a Selenium grid for complete and reliable testing.
Of particular interest is WebdriverIO, which also complies with W3C standards and has broad support from the open source community. It leverages some of the native browser APIs to solve many of the same problems that Cypress, TestCafe, and Playwright address.
As developers adopt DevOps, test automation needs to be robust to run each time code is committed and to provide tools for debugging. Sauce Labs has preconfigured Docker images and VMs for each framework that can be leveraged to run tests in the cloud at scale through the saucectl CLI. This lets a team test locally, or on CI at scale. And no matter how you test, test assets are sent to the Sauce Cloud for easy debugging with screenshots, videos and logs and historical insights.
Switching test automation frameworks is a big undertaking and you need to make sure you understand the tradeoffs. Start with your testing needs. Which browsers do you need to test on? Who will write automated tests in your organization? Are you integrating with CI/CD? No matter which test automation framework you decide to use, Sauce Labs solutions will let you scale and increase productivity as you shift testing left.
