Answer 1

Try it;

@RunWith(value = SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = { MVCConfig.class, CoreConfig.class, 
        PopulaterConfiguration.class })
public class ExceptionControllerTest {

    private MockMvc mockMvc;

    @Mock
    private StatusController statusController;

    @Autowired
    private WebApplicationContext wac;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void checkUnexpectedExceptionsAreCaughtAndStatusCode500IsReturnedInResponse() throws Exception {

        when(statusController.checkHealth()).thenThrow(new RuntimeException("Unexpected Exception"));

        mockMvc.perform(get("/api/status"))
                .andDo(print())
                .andExpect(status().isInternalServerError())
                .andExpect(jsonPath("$.error").value("Unexpected Exception"));
    }
}
