These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run
flutter_tester to test Dart VM and Flutter integration.
Use this command to run (from the
../../bin/cache/dart-sdk/bin/dart run test test/integration.shard
You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running
../../bin/flutter will automatically download it.
These tests are expensive to run and do not give meaningful coverage information for the
flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.
