Lightning

Lightning is a powerful yet simple Chrome extension designed to streamline the process of testing web applications. It enables you to test both the state and behavior of your web apps efficiently by tracking network requests made via XMLHttpRequest and fetch, with options to block actual requests. The extension also monitors modal dialogs such as alert, confirm, and prompt, ensuring comprehensive test coverage.

With Lightning, you can add operators to wait for arbitrary conditions, handle navigation events seamlessly, and maintain test script continuity despite page transitions. It also supports undoing remote changes through cleanup URLs, linking test scripts to multiple URLs for flexible test entries, and organizing tests into suites for better navigation and selective execution. Tests are saved locally, allowing easy transfer and backup, making Lightning an essential tool for developers seeking reliable and organized web testing workflows.
