patrol

patrol #

patrol package builds on top of flutter_test and integration_test to make
it easy to control the native UI from Dart test code. Created and supported by
LeanCode.
It must be used together with patrol_cli.
It also provides a new custom finder system to make Flutter widget tests more
concise and understandable, and writing them – faster and more fun. It you want
to only use custom finders, check out
patrol_finders.
Installation #
$ dart pub add patrol --dev
