The test for the controller does not work, what's the problem?

Question

Spring

I recently started learning Spring MVC and stumbled upon a problem while writing tests.
Constantly getting this error:
java.lang.AssertionError: Status
Expected: 200
Actual: 404
Test class:

ControllerTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@WebAppConfiguration
public class ControllerTest {
    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext ctx;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.ctx).build();

    }


    @Test
    public void getWordTest() throws Exception {
        mockMvc.perform(get("/test").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk());
    }

}

Controller:

Controller

@EnableWebMvc
@RestController
public class Controller {
    @RequestMapping(value = "/test")
    @ResponseBody
    public String getTestString() {
        return "hello";
    }
}

Config:

webconfig

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "pe4nik.config")
public class WebConfig extends WebMvcConfigurerAdapter {

}

AppInitializer

public class AppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        WebApplicationContext context = getContext();
        servletContext.addListener(new ContextLoaderListener(context));
        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("DispatcherServlet",
                new DispatcherServlet(context));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }

    private AnnotationConfigWebApplicationContext getContext() {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.setConfigLocation("pe4nik.config");
        return context;
    }

}

Judging by the logs, the controller is not created or registered for you. For fidelity, in Before , you can check for the presence in the context of beans of the Controller class.
