Question

我有一个SpringBoot REST API连接到Oracle DB。

我的控制器调用BusinessImpl层，然后BusinessImpl依次调用多个DAO层（Controller -> BusinessImpl -> DAO1, DAO2, DAO3）

下面的测试用例完美运行

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration()
@TestPropertySource("classpath:dev-manifest.yml")
@ContextConfiguration(classes = Application.class)
@ConfigurationProperties(prefix = "env")
@SpringBootTest
public class MyTest
{
  private static final String REQUEST_URI = "/v1/registration/accounts/links";
  private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(),
      MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

  private MockMvc mockMvc;

  @Autowired
  private WebApplicationContext webApplicationContext;

  @Before
  public void setup()
  {
    this.mockMvc = webAppContextSetup(webApplicationContext).build();
  }

  @Test
  public void testSave()
  {
      String testInput = "some json input";
      mockMvc.perform(post(REQUEST_URI).content(testInput).contentType(contentType))
          .andExpect(status().isOk());
  }

但是我不想在junit测试用例期间访问真实数据库。所以我写了一个模拟。

工作代码

  @Mock
  private SecurityAuditDAO securityAuditDAO;

  @InjectMocks
  private RegistrationBusinessImpl registrationBusinessImpl;

  @Test
  public void testSave()
  {
      when(securityAuditDAO.getState(Mockito.any())).thenReturn("somestring");
      SomeRequest someRequest = new SomeRequest();
      someRequest.setStatus("SUCCESS");
      SomeResponse status = registrationBusinessImpl.createUser(SomeRequest, "127.0.0.1");
  }

上面的代码运行完美。在businessImpl类中，securityAuditDAO.getState返回“ somestring”。但是当我引入了mockMvc.perform时，它就停止了工作。

不起作用

  @Test
  public void testSave()
  {
      when(securityAuditDAO.getState(Mockito.any())).thenReturn("somestring");
      String testInput = "some json input";
      mockMvc.perform(post(REQUEST_URI).content(testInput).contentType(contentType))
          .andExpect(status().isOk());
  }

上面的代码仍在访问数据库。因此，我意识到我应该使用securityAuditDAO注入mockMvc，因此我添加了以下行

this.mockMvc = MockMvcBuilders.standaloneSetup(securityAuditDAO).build();

代码

  private MockMvc mockMvc;

  @Autowired
  private WebApplicationContext webApplicationContext;

  @Mock
  private SecurityAuditDAO securityAuditDAO;

  @InjectMocks
  private RegistrationBusinessImpl registrationBusinessImpl;

  @InjectMocks
  RegistrationApiController registrationApiController;  

  @Before
  public void setup()
  {
    MockitoAnnotations.initMocks(this);
    //this.mockMvc = webAppContextSetup(webApplicationContext).build();
    this.mockMvc = MockMvcBuilders.standaloneSetup(securityAuditDAO).build();
    //this.mockMvc = MockMvcBuilders.standaloneSetup(registrationApiController).build();
    //ReflectionTestUtils.setField(mockMvc, "securityAuditDAO", securityAuditDAO);
  }

我尝试注入securityAuditDAO。但是，如果这样做，BusinessImpl中的其他自动装配实例将为空。如何注入securityAuditDAO而不影响其他对象，或者如何注入webApplicationContext和securityAuditDAO。还尝试了ReflectionTestUtils.setField，但是没有按预期工作。

如何在Spring Boot REST Junit测试案例中向多个对象注入MockMvc
