How to run the testing directory tests

The 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 --directory testing/test_app
    
  • Fetch dependencies for the web_benchmarks directory:

    flutter pub get
    
  • Run the tests with flutter test:

    $ flutter test testing
