春季启动：JUnit测试ApplicationContext加载失败

Question

包含集成测试的单个测试用例具有java.lang.IllegalStateException: Failed to load ApplicationContext。

我使用MongoDb和spring存储库对REST应用程序进行了一系列单元和集成测试。

问题是只有在还运行集成测试类时，单个测试用例才会失败。 mvn test。

运行所有单元测试没有错误。运行所有集成测试都没有错误。

只有在进行单元和集成测试时才会发生错误。

将所有测试运行两次，第一次迭代；测试用例有ApplicationContext错误，但没有第二次迭代。

I've had similar issue with unit tests only

所有测试运行一次：

所有测试运行两次：

堆栈跟踪：

@AutoConfigureMockMvc导致了我从集成测试中自动配置MockMvc的方式出现问题。

改为使用@ContextConfiguration，并使用MockMvc手动设置WebApplicationContext。

IntegrationTest.java

@SpringBootTest
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class UserIntegrationTest {

    @Autowired
    private WebApplicationContext context;

    private MockMvc mockMvc;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders
                .webAppContextSetup(context)
                .build();
    }
    //... etc codes
