Java Question

WebApplicationContext doesn't autowire

I write this test class :

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
public class CandidateControllerTest {

@Mock(name = "candidateService")
private CandidateService candidateService;

@InjectMocks
private CandidateMenuController candidateMenuController = new CandidateMenuController();


@Autowired
WebApplicationContext wac;

MockMvc mockMvc;


@Before
public void before() {



mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();
}
}


But:

After code execution I see next trace:

java.lang.IllegalArgumentException: WebApplicationContext is required

What Would I do for fixing my problem?

UPDATE

I change code:

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
public class CandidateControllerTest {

@Mock(name = "candidateService")
private CandidateService candidateService;

@InjectMocks
private CandidateMenuController candidateMenuController = new CandidateMenuController();

@Autowired
WebApplicationContext wac;

MockMvc mockMvc;

@Before
public void before() {
MockitoAnnotations.initMocks(this);

// this.mockMvc =
// MockMvcBuilders.webAppContextSetup(this.wac).dispatchOptions(true).build();

mockMvc = MockMvcBuilders.webApplicationContextSetup(wac).build();

}
...
}

Answer

There is no WebApplicationContext only an ApplicationContext unless you add the @WebAppConfiguration to your test class.

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class CandidateControllerTest { ... }

Instead of the @RunWith annotation you can also extend one of springs convenience classes.

@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
@WebAppConfiguration
public class CandidateControllerTest extends AbstractJUnit4SpringContextTests { ... }
