Another approach in integration testing is to define a new Configuration class and provide it as your @ContextConfiguration. Into the configuration you will be able to mock your beans and also you must define all types of beans which you are using in test/s flow.
To provide an example :
@RunWith(SpringRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class MockTest{
@Configuration
static class ContextConfiguration{
// ... you beans here used in test flow
@Bean
public MockMvc mockMvc() {
return MockMvcBuilders.standaloneSetup(/*you can declare your controller beans defines on top*/)
.addFilters(/*optionally filters*/).build();
}
//Defined a mocked bean
@Bean
public MyService myMockedService() {
return Mockito.mock(MyService.class);
}
}
@Autowired
private MockMvc mockMvc;
@Autowired
MyService myMockedService;
@Before
public void setup(){
//mock your methods from MyService bean
when(myMockedService.myMethod(/*params*/)).thenReturn(/*my answer*/);
}
@Test
public void test(){
//test your controller which trigger the method from MyService
MvcResult result = mockMvc.perform(get(CONTROLLER_URL)).andReturn();
// do your asserts to verify
}
}
