Integration tests
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 flutter_tools
directory):
../../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.
Coverage exclusion
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.
Adding new test files
When adding a new test file make sure that it ends with _test.dart
, or else it will not be run.
