  class EmptyClass { }
  let instance: HasInitialized;

  beforeEach(() => {
    const classWithHasInitialized = mixinInitialized(EmptyClass);

  });

  it('should emit for subscriptions made after the directive was marked as initialized', done => {
    // Mark the class as initialized so the stream emits when subscribed and the test completes.
