  17  * Listens to sbt test listener events and writes them to a tap compatible file. Results for all groups
  18  * go to a single file although it might be desirable to generate one tap file per group.
  19  * <p>
  20  * sbt runs tests in parallel and the protocol does not seem to provide a way to match a group to a test event. It
  21  * does look line one thread calls startGroup/testEvent/endGroup sequentially and using thread local to keep
  22  * the current active group might be one way to go.
