Question

我有一个案例，我的mockito测试都是单独传递但在作为测试套件的一部分运行时可能会失败。我正在使用mockito版本2.9.0

我的测试类如下

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.BDDMockito;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.cache.CacheServices;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(value={"classpath:generalConfig/generalConfigMocks-context.xml"})
public class GeneralConfigAPIClientTest {

    private MockMvc mockMvc;

    @Autowired
    CacheServices cacheServices; 

    @Autowired
    IGeneralConfigServices generalConfigServices;

    @Autowired 
    private WebApplicationContext wac;

    /**
     * Set up the test context, initialize the mockMvc.
     * */
    @Before 
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();       
    }

    @Test
    public void testEmptyGeneralConfigCache_FailureFalseReturned() throws Exception {

        BDDMockito.given(cacheServices.emptyCacheContents(BDDMockito.anyString())).willReturn(false);

        this.mockMvc.perform(get("/generalConfig/emptyGeneralConfigCache"))
                .andExpect(status().isOk())     
                .andReturn();

        BDDMockito.verify(cacheServices, BDDMockito.times(1)).emptyCacheContents(BDDMockito.anyString());
    }

    @Test
    public void testEmptyGeneralConfigCache_SuccessTrueReturned() throws Exception {
        BDDMockito.given(cacheServices.emptyCacheContents(BDDMockito.anyString())).willReturn(true);

        this.mockMvc.perform(get("/generalConfig/emptyGeneralConfigCache"))
                .andExpect(status().isOk())     
                .andReturn();

        BDDMockito.verify(cacheServices, BDDMockito.times(1)).emptyCacheContents(BDDMockito.anyString());
    }

    }

generalConfig / generalConfigMocks-context.xml的内容如下

    <bean id="generalConfigServices" class="org.mockito.BDDMockito" factory-method="mock">

    <bean id="cacheServices" class="org.mockito.BDDMockito" factory-method="mock">
        <constructor-arg value="com.cache.CacheServices"/>
    </bean>


</beans>

我从运行测试中获得的示例错误响应如下

    org.mockito.exceptions.verification.TooManyActualInvocations: 
cacheServices.emptyCacheContents(
    <any string>
);
Wanted 1 time:

But was 2 times. Undesired invocation:

任何人都可以提供任何有关我的测试单独传递但是作为一组失败的原因的见解

Answer 1

原因：您的测试在内部使用bean mock加载一个应用程序上下文。任何测试后豆粪都很脏。您也有一个脏的应用程序上下文。

解决方案：你必须清理bean mock。每次测试后使用Mockito.reset（模拟）。我找到了类似的东西：How to clean up mocks in spring tests when using Mockito

Answer 2

我迟到了，但我认为这对仍然遇到相同问题的人有用（来源：https://reflectoring.io/clean-unit-tests-with-mockito/）：

class CityServiceImplTest {

  // System under Test (SuT)
  private CityService cityService;

  // Mock
  private CityRepository cityRepository;

  @BeforeEach
  void setUp() {
    cityRepository = Mockito.mock(CityRepository.class);
    cityService = new CityServiceImpl(cityRepository);
  }

  // Test cases omitted for brevity.

}

通过这种方法，我完全消除了 @SpringBootTest 注释，并使测试类的重量非常轻。

Mockito Tests单独通过，但作为套房的一部分失败
