// TODO: Mention on each Reporter method that it does nothing

// There's no way to really pass along a suiteStarting or suiteCompleted
// report. They have a dumb comment to "Do not invoke" fireTestRunStarted
// and fireTestRunFinished, so I think they must be doing that themselves.
// This means we don't have a way to really forward runStarting and
// runCompleted reports either. But runAborted reports should be sent
// out the door somehow, so we report them with yet another fireTestFailure.

  // This form isn't clearly specified in JUnit docs, but some tools may assume it, so why rock the boat.
  // Here's what JUnit code does:
  //   public static Description createTestDescription(Class clazz, String name, Annotation... annotations) {
  //       return new Description(String.format("%s(%s)", name, clazz.getName()), annotations);
  //   }
  // So you can see the test name shows up, which is normally a test method name, followed by the fully qualified class name in parens
  // We put test name and suite class name (or suite name if no class) in parens, but don't try and do anything to get rid of spaces or
  // parens the test or suite names themselves, since it is unclear if this format is used by anyone anyway. If actual bug reports come
  // in, then we can fix each actual problem once it is understood.
