🚀 Nightwatch v3 What's New | Release Notes | Discussions
Nightwatch v3 is an all new generation that has been built around these three pillars:
Developer Experience : The entire experience from getting started, to writing and debugging tests, has been redesigned for speed, stability, and consistent non-flaky results.
Mobile first: Test your web or native, iOS and Android, mobile applications on simulators, real mobile devices or a cloud grid like BrowserStack.
One test automation framework: Run all types of tests from unit, component, and E2E to API, visual, and accessibility with a single framework.
The Nightwatch v3 is not just a new version, it’s the result of months of engineering effort to reimagine test automation for the future. Try it out in 60 seconds and see it in action.
