ApplicationEventPublisher mocked with MockBean is not injected in component under test

Version of Spring Boot: 1.4.0.M3

I have an integration test, annotated with

@RunWith(SpringRunner::class)
@SpringBootTest
@AutoConfigureMockMvc

and where I have

    @MockBean
    private lateinit var mockApplicationEventPublisher: ApplicationEventPublisher

    @Autowired
    private lateinit var mockMvc: MockMvc

Kotlin code, equivalent to

    @MockBean
    private ApplicationEventPublisher mockApplicationEventPublisher;

    @Autowired
    private MockMvc mockMvc;

The controller under test does call publishEvent() on the event publisher, but when I verify that the calls have been made using

    verify(mockApplicationEventPublisher).publishEvent(ScoreSubmittedEvent()))

I get the following error:

Wanted but not invoked:
org.springframework.context.ApplicationEventPublisher#0 bean.publishEvent(...);
-> at com.ninja_squad.ng2propack.pack.ScoreControllerTest.should submit score(ScoreControllerTest.kt:89)
Actually, there were zero interactions with this mock.

When I debug, I notice that the publisher in the test is indeed a Mockito-generated proxy, but that the publisher injected in the controller under test is the non-mocked instance of org.springframework.web.context.support.GenericWebApplicationContext.

I guess the root caus is that the bean implementing ApplicationEventPublisher is not an actual separate bean, but is the spring application context itself.

A workaround would be to use my own event publisher bean that would simply delegate to the actual spring event publisher, but that’s something I shouldn’t have to do.
