嘿,在创建测试用例时,我已经开始使用spring boot Test框架进行spring-boot junit测试,我面临以下问题。

    import static org.hamcrest.Matchers.containsString;
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    import org.springframework.test.web.servlet.MockMvc;


    @RunWith(SpringRunner.class)
    @SpringBootTest
    @AutoConfigureMockMvc
    public class ApplicationTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void shouldReturnDefaultMessage() throws Exception {
        this.mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk())
                .andExpect(content().string(containsString("Hello World")));
    }
}

在上述代码中,我收到

的错误
    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)}**

我知道spring-boot找不到MockMvc名称bean,但是为什么它找不到它,我怎么做才能使应用程序正常工作。

希望您具有spring-boot-starter-web依赖性。不知道您使用的是哪种版本的Spring Boot,而是用这种方式来构建ockMockMvc?

@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTest {

  @Autowired
  private WebApplicationContext webApplicationContext;
  private MockMvc mockMvc;

  @Before
  public void setUp() {
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
  }

我遇到了同样的问题,因为我正在学习使用WebFlux(反应性Web)而不是同步Web的教程。假设单元测试可以是同步的,那么最终这对我有用(在Gradle中)

implementation 'org.springframework.boot:spring-boot-starter-webflux'
// Required for MockMvc autoconfigure
testImplementation 'org.springframework.boot:spring-boot-starter-web'
