Spring boot 使用Mockito进行的Spring启动测试：@在单元测试期间，已验证的注释被忽略

我使用的是SpringBoot2.1.1、JUnit5和Mockito2.23.4

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.mockito</groupId>
            <artifactId>mockito-core</artifactId>
            <version>2.23.4</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.mockito</groupId>
            <artifactId>mockito-junit-jupiter</artifactId>
            <version>2.23.4</version>
            <scope>test</scope>
        </dependency>

此测试导致以下故障：

java.lang.AssertionError: Status expected:<400> but was:<200>
Expected :400
Actual   :200

java.lang.AssertionError:应为状态：但为：
预计：400
实际：200

既然@Valid注释通过了我的其他测试用例，并且它们在不加载Spring上下文的情况下工作，那么有没有办法让@Validated注释在Mockito（同样，在不加载Spring上下文的情况下）也能工作呢？

也许您可以尝试使用

@WebMvcTest

并添加

SpringExtension

@ExtendWith({SpringExtension.class, MockitoExtension.class})
@WebMvcTest(AramaController.class)
class AramaControllerTest {

    @Mock
    private AramaService aramaService;

    @InjectMocks
    private AramaController aramaController;

    @Autowired
    private MockMvc mockMvc;

    @Test
    void aramaValidationError() throws Exception {

        mockMvc
                .perform(
                        get("/arama").param("query", "a")
                )
                .andExpect(status().isBadRequest());

        verifyNoMoreInteractions(aramaService);
    }
}

我在别处得到了答案，并想与大家分享：

如果不启动上下文，您将无法获得@Validator 测试，因为验证器实例是Springbean。但是，@有效 将按照JSR-303标准工作

到目前为止，我能建议的是

@SpringBootTest
@ExtendWith(SpringExtension.class)

既然可以在不加载Spring上下文的情况下测试“@Valid”注释，那么有没有办法使“@Validated”注释也能工作呢？当您有

@springbootest

注释时，

@ExtendWith

注释是多余的。

@ExtendWith(MockitoExtension.class)
class AramaControllerTest {

    @Mock
    private AramaService aramaService;

    @InjectMocks
    private AramaController aramaController;

    private MockMvc mockMvc;

    @BeforeEach
    private void setUp() {
        mockMvc = MockMvcBuilders
                .standaloneSetup(aramaCcontroller)
                .setControllerAdvice(new RestResponseEntityExceptionHandler())
                .build();

    }

    @Test
    void aramaValidationError() throws Exception {

        mockMvc
                .perform(
                        get("/arama").param("query", "a")
                )
                .andExpect(status().isBadRequest());

        verifyNoMoreInteractions(aramaService);
    }
}

java.lang.AssertionError: Status expected:<400> but was:<200>
Expected :400
Actual   :200

@ExtendWith({SpringExtension.class, MockitoExtension.class})
@WebMvcTest(AramaController.class)
class AramaControllerTest {

    @Mock
    private AramaService aramaService;

    @InjectMocks
    private AramaController aramaController;

    @Autowired
    private MockMvc mockMvc;

    @Test
    void aramaValidationError() throws Exception {

        mockMvc
                .perform(
                        get("/arama").param("query", "a")
                )
                .andExpect(status().isBadRequest());

        verifyNoMoreInteractions(aramaService);
    }
}

@SpringBootTest
@ExtendWith(SpringExtension.class)
