When I try to compile and run FlexUnit 4 tests from Flash CS4, there is a run-time error that no tests were found. I believe the cause is that the custom [Test] metadata didn't make it into the SWF, because MXMLC by default does not keep custom AS3 metadata. And unfortunately, Flash CS4 doesn't allow you to supply additional compiler arguments.
Is there a way to use FlexUnit 4 with Flash CS4?
