使用 Junit 和 Mock put 请求进行测试

Question

我正在尝试对放置请求进行测试，它在这种类型的请求中给了我空指针错误我不知道为什么请有人帮助我，这是我的控制器:

@PutMapping ("/update/{id}")
    public Entreprise updateEntreprise(@PathVariable Long id,@RequestBody Entreprise entreprise ) {
       Entreprise e=entrepriseService.getEntreprise(id);
       e.setDescription(entreprise.getDescription());
       e.setNom(entreprise.getNom());
       e.setNumberCertificats(entreprise.getNumberCertificats());
       e.setNumberClients(entreprise.getNumberClients());
       e.setNumberYears(entreprise.getNumberYears());
       e.setNumberCollaborators(entreprise.getNumberCollaborators());
       entrepriseService.updateEntreprise(e);
        return e;
    }

测试方法：

@RunWith(SpringRunner.class)
@WebMvcTest(value = EntrepriseController.class, secure = false)
public class TestsEntrepriseController {
    @Autowired
    private MockMvc mockMvc;


    @MockBean
    EntrepriseService entrepriseService;
 @Test
    public void givenEntrepriseURIWithPut_whenMockMVC_thenVerifyResponse() throws Exception {
        Entreprise entreprise = new Entreprise();
        entreprise.setId(1);
        entreprise.setNom("oumaima");
        entreprise.setDescription("description");
        entreprise.setNumberCertificats(12);
        entreprise.setNumberClients(15);
        entreprise.setNumberCollaborators(20);
        entreprise.setNumberYears(12);
        Services services = new Services();
        services.setNom("cloud");
        services.setId(1);
        Set<Services> allServices =  new HashSet<>(Arrays. asList(services));
        entreprise.setServices(allServices);
        mockMvc.perform(put("/entreprise/update/1")
                .contentType(IntegrationTestUtil.APPLICATION_JSON_UTF8)
                .content(IntegrationTestUtil.convertObjectToJsonBytes(entreprise))
        )
                .andExpect(status().isBadRequest())
                .andExpect(content().string("{\"fieldErrors\":[{\"path\":\"title\",\"message\":\"The title cannot be empty.\"}]}"));

    }
}

Answer 1

我没有看到你模拟服务调用。添加 - Mockito.when(entrepriseService.getEntreprise(Mockito.anyLong())).thenReturn(new Entreprise())

Answer 2

您需要模拟来自 entrepriseService

的两个调用

对于 getEntreprise(id)
更新企业(e)

尝试运行下面的代码

@RunWith(SpringRunner.class)
@WebMvcTest(value = EntrepriseController.class, secure = false)
public class TestsEntrepriseController {
    @Autowired
    private MockMvc mockMvc;


    @MockBean
    EntrepriseService entrepriseService;
 @Test
    public void givenEntrepriseURIWithPut_whenMockMVC_thenVerifyResponse() throws Exception {
        Entreprise entreprise = new Entreprise();
        entreprise.setId(1);
        entreprise.setNom("oumaima");
        entreprise.setDescription("description");
        entreprise.setNumberCertificats(12);
        entreprise.setNumberClients(15);
        entreprise.setNumberCollaborators(20);
        entreprise.setNumberYears(12);
        Services services = new Services();
        services.setNom("cloud");
        services.setId(1);
        Set<Services> allServices =  new HashSet<>(Arrays. asList(services));
        entreprise.setServices(allServices);

        Mockito.when(entrepriseService.getEntreprise(Mockito.any())).thenReturn(new Entreprise());
        Mockito.when(entrepriseService.updateEntreprise(Mockito.any(Entreprise .class))).thenReturn(entreprise);

        mockMvc.perform(put("/entreprise/update/1")
                .contentType(IntegrationTestUtil.APPLICATION_JSON_UTF8)
                .content(IntegrationTestUtil.convertObjectToJsonBytes(entreprise))
        )
                .andExpect(status().isBadRequest())
                .andExpect(content().string("{\"fieldErrors\":[{\"path\":\"title\",\"message\":\"The title cannot be empty.\"}]}"));

    }
}

使用 Junit 和 Mock put 请求进行测试

Testing using Junit and Mock put request

java

junit

mockito

spring-boot
