Better debugging to investigate: https://github.com/flutter/flutter/issues/125241 When the `test/integration.shard/break_on_framework_exceptions_test.dart` test times out, log out verbose logging to give clues as to why it did not complete. From one local run it looks like the test runner is failing to load a test file (when I checked the path locally, the file was there, and re-running the `flutter test ...` invocation succeeded--in that the app threw an exception): ``` 14:12 +26 -1: breaks when StatefulWidget.build throws [E] Timed out launching `flutter test` package:matcher fail

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.
