MockMvc没有此类bean异常

Question

当我尝试使用模拟mvc时，没有得到此类bean异常。看来自动配置mvc方法不起作用。不确定为什么会这样。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

下面是代码

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = AssessmentanalyticsApplication.class)
@AutoConfigureMockMvc
public class AssessmentanalyticsApplicationTests {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void contextLoads() throws Exception {
        AssessmentAttemptData data = new AssessmentAttemptData();
        data.setAssessmentAttemptCount("1");
        data.setAssessmentCompletionCount("2");
        data.setAssessmentId("1");
        data.setHighScore(new BigDecimal(1));
        data.setLowScore(new BigDecimal(1));
         MvcResult result = (MvcResult) mockMvc.perform(MockMvcRequestBuilders.post("/assessmentanalytics/recordAttempt")
             .accept(MediaType.APPLICATION_JSON));
    }
}
