## "Application"The `lib/test.dart` and `lib/control.dart` files in this directory areused by `dev/bots/test.dart`'s `runTracingTests` function to checkwhether aspects of the tracing logic in the framework get compiled outin profile and release builds. They're not meant to be run directly.The strings in these files are used in `dev/bots/test.dart`.## Tests
The tests in this folder must be run with `flutter test --enable-vmservice`,since they test that trace data is written to the timeline by connecting tothe observatory.
