THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
- The FlexUnit4Builder is the last builder run in the AllDefaultPossibilitiesBuilder, and is the catch-all for any tests that don't fit the criteria for any other Builder, and it will return an instance of BlockFlexUnit4ClassRunner.
override public function runnerForClass( testClass:Class ):IRunner {
return new BlockFlexUnit4ClassRunner(testClass);
}
