I have a basic SpringBoot app., embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file.
I have this class:
@Service
public class I18NService {
/** The application logger */
private static final Logger LOG = LoggerFactory.getLogger(I18NService.class);
@Autowired
private MessageSource messageSource;
...
}
this controller
@Controller
public class ForgotMyPasswordController extends TdkController {
@Autowired
private I18NService i18NService;
@Autowired
private EmailService emailService;
...
}
Start the application works fine, This Test also is working perfectly
public class ForgotMyPasswordControllerTests {
private ForgotMyPasswordController controller;
@Before
public void setUp() throws Exception {
controller = new ForgotMyPasswordController();
}
@Test
public void testHandleListRequest() {
assertEquals("forgotmypassword/emailForm", controller.forgotPasswordGet());
}
}
but when I run this one :
@RunWith(SpringRunner.class)
@WebAppConfiguration
@WebMvcTest
public class MockMvcTests {
// Pull in the application context created by @ContextConfiguration
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
// Setup MockMVC to use our Spring Configuration
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void getDeviceEventsTest() throws Exception {
this.mockMvc
.perform(get("/forgotmypassword") //
.accept(MediaType.parseMediaType("text/html;charset=UTF-8")))
.andExpect(status().isOk()) //
.andExpect(model().size(0)); //
}
}
I got this error:

Typically @WebMvcTest is used in combination with @MockBean or @Import to create any collaborators required by your @Controller beans. If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than this annotation.
Annotation Type AutoConfigureMockMvc Annotation that can be applied to a test class to enable and configure auto-configuration of MockMvc .
@RunWith(SpringRunner.class) provides a bridge between Spring Boot test features and JUnit. Whenever we are using any Spring Boot testing features in our JUnit tests, this annotation will be required.
The MockMvcBuilders. standaloneSetup allows to register one or more controllers without the need to use the full WebApplicationContext .
The whole point of WebMvcTest is to only load the MVC components. Other components must be mocked. Read the documentation:
To test Spring MVC controllers are working as expected you can use the @WebMvcTest annotation. @WebMvcTest will auto-configure the Spring MVC infrastructure and limit scanned beans to @Controller, @ControllerAdvice, @JsonComponent, Filter, WebMvcConfigurer and HandlerMethodArgumentResolver. Regular @Component beans will not be scanned when using this annotation.
Often @WebMvcTest will be limited to a single controller and used in combination with @MockBean to provide mock implementations for required collaborators.
