我如何执行Junit测试？

Question

我使用jhipster控制器的生成器通过以下命令生成了该测试的一部分：jhipster generate-controller NAME-CONTROLLER但是我不知道如何尝试编织测试，我拥有的代码是：

     * Test class for the NotificationResource REST controller.
 *
 * @see NotificationResource
 */
@SpringBootTest(classes = MyApp.class)
public class NotificationResourceIT {

    private MockMvc restMockMvc;

    @BeforeEach
    public void setUp() {
        MockitoAnnotations.initMocks(this);

        NotificationResource notificationResource = new NotificationResource();
        restMockMvc = MockMvcBuilders
            .standaloneSetup(notificationResource)
            .build();
    }

    public static String asJsonString(final Object obj) {
        try {
            return new ObjectMapper().writeValueAsString(obj);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    /**
     * Test postNotification
     */
    @Test
    public void testPostNotification() throws Exception {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd.MM.yyyy");
        LocalDate date = LocalDate.parse("02.11.2019",formatter);
        restMockMvc.perform(post("/api/notification/post-notification")
                .contentType(MediaType.APPLICATION_JSON)
                .content(asJsonString(date))
                )
            .andExpect(status().isOk());
    }
}

我正在使用IDE Eclipse，然后选择文件并在“以Junit方式运行”中执行clic，这会给我下一条消息：

并且在控制台中显示下一个：

我需要帮助才能尝试此测试，非常感谢您的帮助

Answer 1

看到您的代码，您是否错过了Test Runner？这是带有Main函数的类，您可以调用要运行的测试。您可以在TutorialsPoint网站上找到一个示例：JUnit Executing Tests。

Answer 2

您可以尝试在类中添加@RunWith（MockitoJUnitRunner.class）批注
