Updates the expected steps in the async function defined within `stepping_project.dart`. The Dart web team is updating the async semantics of DDC to bring them in line with the other backends. Currently, the DDC async semantics don't adhere to the Dart spec and this can lead to inconsistent and surprising results. However, the step-over operation doesn't work well yet with the new DDC async semantics. In the long run we intend to improve this but until then the debug stepper will have sporadic results that we can't model well with this test. When we are able to fix the stepper functionality, we will return this test to cover more of the async function being stepped over.
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.
