Patrol by LeanCode

Patrol is a powerful, open-source testing framework for Flutter apps created and maintained by LeanCode – one of the leading Flutter development consultancies in the world. Patrol builds on top of Flutter's existing test tooling to enable you to do things which were previously impossible.

It lets you access native features of the platform that the Flutter app is running on. Finally, you can interact with permission dialogs, notifications, WebViews, change device settings, toggle Wi-Fi, and much more – and you can code this very easily in plain Dart.

Patrol also provides a new custom finder system that extends Flutter's default finders, making them shorter and easier to understand. Patrol's custom finders, coupled with Hot Restart, make writing integration tests dramatically faster, easier and more fun!

Patrol is also a revamped, production-quality version of Flutter's built-in integration_test plugin. It fixes its shortcomings and enables features such as full isolation between tests and sharding.

Patrol is a fully open-source project and we're proud to share it with the awesome Flutter community.

At LeanCode, we use Patrol to test our clients' production-grade apps, and you can do the same!
