Spring - How to test publishing of an event?

I have a Controller which is publishing an event

@RestController
public class Controller
{
    @Autowired
    private ApplicationEventPublisher publisher;

    @GetMapping("/event")
    public void get()
    {
        publisher.publishEvent(new Event());
    }
}

Now I want to test that the event is published. First I tried to @MockBean the ApplicationEventPublisher and verify the method call. But this does not work according to https://jira.spring.io/browse/SPR-14335

So I am doing it like this:

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = Controller.class)
public class ControllerTest
{
    @Autowired
    private MockMvc mockMvc;

    @Test
    public void getTest() throws Exception
    {
        this.mockMvc.perform(get("/").contentType(MediaType.APPLICATION_JSON)
                    .andExpect(status().isOk());
        assertNotNull(Listener.event);
    }

    @TestConfiguration
    static class Listener
    {
        public static Event event;

        @EventListener
        void listen ( Event incoming )
        {
            event = incoming;
        }
    }
}

Is there an easier way for this common use case?
