Test ExceptionHandling with MockMvc and Mockito - spring

Question

I want to test my RestController with MockMvc and Mockito. I have providerController with injected service and providerService throw ProviderNotFoundException if prover with this id not found. Also i have ExceptionHandler for this exception.
#RestController
#RequestMapping
public class ProviderController {
#Autowired
private ProviderService providerService;
#Autowired
private RestErrorFactory restErrorFactory;
...
#RequestMapping(value = "/{id}")
public Provider findOne(#PathVariable("id") String id) throws ProviderNotFoundException {
return providerService.findOne(id);
}
#ExceptionHandler(ProviderNotFoundException.class)
#ResponseStatus(HttpStatus.NOT_FOUND)
public #ResponseBody RestError providerNotFound(ProviderNotFoundException exception) {
return restErrorFactory.create(HttpStatus.NOT_FOUND,
String.format("Provider with id '%s' not found", exception.getRequestedId()));
}
}
This controoler work's fine. But when i try to test it i have such code:
#RunWith(MockitoJUnitRunner.class)
public class ProviderControllerTest {
#InjectMocks
private ProviderController providerController;
#Mock
private ProviderService providerService;
private MockMvc mockMvc;
#Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(providerController)
.apply(documentationConfiguration(restDocumentation))
.build();
}
...
#Test
public void testFindOneNotFound() throws Exception {
when(providerService.findOne(anyString()))
.thenThrow(new ProviderNotFoundException(anyString()));
this.mockMvc
.perform(
get("/pizza-house")
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isNotFound());
verify(providerService, times(1)).findOne(anyString());
verifyNoMoreInteractions(providerService);
}
}
And this test failed, i got following stacktrace:

Therefore my ExceptionHandler didnt called from tests. I try to replace standaloneSetup to webAppContextSetup and this problem fixed but first of all this test became integration instead of unit and second i can't mock service using Mockito.
Please help me configure exception handling using standaloneSetup or mock my service using Mockito. Thank you in advance.
