Handles responses from concurrent junit
Stuff to remember about JUnit threading:
parallel=classes; beforeClass/afterClass, constructor and all tests method run on same thread
parallel=methods; beforeClass/afterClass run on main thread, constructor + each test method run on same thread
parallel=both; same as parallel=methods
Noteworthy things about JUnit4 listening:
A class that is annotated with @Ignore will have one invocation of "testSkipped" with source==name
A method that is annotated with @Ignore will have a invocation of testSkipped with source and name distinct
Methods annotated with @Ignore trigger no further events.
