SpringBootでのWebMvcTest

基本的なSpringBootアプリ、組み込みTomcat、Thymeleafテンプレートエンジン、および実行可能JARファイルとしてのパッケージがあります。

私はこのクラスを持っています：

@Service
public class I18NService {

    /** The application logger */
    private static final Logger LOG = LoggerFactory.getLogger(I18NService.class);

    @Autowired
    private MessageSource messageSource;

    ...
}

このコントローラー

@Controller
public class ForgotMyPasswordController extends TdkController {


    @Autowired
    private I18NService i18NService;

    @Autowired
    private EmailService emailService;

...
}

アプリケーションの起動は正常に機能します。このテストも完全に機能しています

public class ForgotMyPasswordControllerTests {

    private ForgotMyPasswordController controller;

    @Before
    public void setUp() throws Exception {
        controller = new ForgotMyPasswordController();
    }


    @Test
    public void testHandleListRequest() {
        assertEquals("forgotmypassword/emailForm", controller.forgotPasswordGet());
    }

}

しかし、私がこれを実行すると：

@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)); //

    }
}

このエラーが発生しました：

WebMvcTestの要点は、MVCコンポーネントのみをロードすることです。他のコンポーネントはモックする必要があります。読む ドキュメント ：

Spring MVCコントローラーが期待どおりに機能していることをテストするには、@ WebMvcTestアノテーションを使用できます。 @WebMvcTestは、Spring MVCインフラストラクチャを自動構成し、スキャンされたBeanを@ Controller、@ ControllerAdvice、@ JsonComponent、Filter、WebMvcConfigurer、およびHandlerMethodArgumentResolverに制限します。このアノテーションを使用すると、通常の@ComponentBeanはスキャンされません。

多くの場合、@ WebMvcTestは単一のコントローラーに制限され、@ MockBeanと組み合わせて使用​​され、必要な共同作業者に模擬実装を提供します。
