 @Inject
 private EventFixture fixture;

 fixture.given(eventFactory.createMyEvent())
     .whenFired()
     .wasHandledBy(MyHandler.class);
 

• Test that a given event was handled by exactly a provided list of EventHandlers:

 @Inject
 private EventFixture fixture;

 fixture.given(eventFactory.createMyEvent())
     .whenFired()
     .wasHandledExactlyBy(MyHandler.class, MyHandler2.class);
 

• Test that a given event was not handled by an expected EventHandler:

 @Inject
 private EventFixture fixture;

 fixture.given(eventFactory.createMyEvent())
     .whenFired()
     .wasNotHandledBy(MyHandler3.class);
 

• Test that a given event was generated from an expected method() with appropriate *parameters*

 @Inject
 private EventFixture fixture;

 MyEvent myEvent = eventFactory.createMyEvent(SOME_EVENT_PARAM);
 fixtures.given(MyService.class)
     .whenCalled("doSomething", SOME_METHOD_PARAM)
     .eventWasHandledBy(myEvent, MyHandler.class);
