  18  * Listens to sbt test listener events and writes them to a tap compatible file. Results for all groups

  20  * <p>
  21  * sbt runs tests in parallel and the protocol does not seem to provide a way to match a group to a test event. It
  22  * does look line one thread calls startGroup/testEvent/endGroup sequentially and using thread local to keep
  23  * the current active group might be one way to go.
