testing READMEtesting directory testsThe benchmarks contained in this directory use a client-server model, similar to what the integration_test package does. In order to run the tests inside testing, do the following:
Install Chrome in a way that tests can find it.
Fetch dependencies for the test_app directory inside testing:
flutter pub get testing/test_app
Fetch dependencies for the web_benchmarks directory:
flutter pub get
Run the tests with flutter test:
