Just a thought, we can probably extend the run_integration_test script for use with other directories (like the dart_runner integration tests, etc)?

Yes I think it should work fine for that usecase. Some stuff will need to be changed:

• instead of building from fuchsia/flutter it should build from fuchsia/dart
• the warning about headless environments should be disabled (maybe even removed outright, I haven't seen any issues running the tests from a headless environment yet)
• The script will need to copy over the oot_dart_jit_runner instead of the oot_flutter_jit_runner.

I think flipping all of that stuff can be based on whether the test name is a Dart integration test vs. Flutter integration test.
