"After all tests in all containers"

[io7m]

Hello!

Is there any way by which an extension can be notified that all tests in all containers have finished executing? The AfterAllCallback extension point is executed once per container, and there doesn't appear to be any way to determine if another container of tests is due to follow.

Answering my own question: Register a LauncherSessionListener in the extension (from the JUnit Platform). The obtained launcher session can be used to register a TestExecutionListener, which has its testPlanExecutionFinished method called when all tests in all containers have finished.

Essentially:

public final class MiscExtension
  implements LauncherSessionListener,
  TestExecutionListener
{
  public MiscExtension()
  {

  }

  @Override
  public void launcherSessionOpened(
    final LauncherSession session)
  {
    session.getLauncher()
      .registerTestExecutionListeners(this);
  }

  @Override
  public void launcherSessionClosed(
    final LauncherSession session)
  {

  }

  @Override
  public void testPlanExecutionFinished(
    final TestPlan testPlan)
  {
     // Called exactly once at the end
  }
