Question

在Spring引导框架中，我发现使用JUnit和Mockito进行控制器单元测试很困难。我想测试这种方法。如何测试DELETE请求方法：

//删除应用程序 控制器类

    @DeleteMapping("/applications")
    public String deleteApplicationByObject(@RequestBody Application application) {
        applicationService.deleteById(application.getId());
        return "Deleted";
    }

//删除应用程序 服务等级

    @Override
    @Transactional
    public String removeById(Long id) {
        dao.deleteById(id);
        return "SUCCESS";
    }

//删除应用程序道课

    @Override
    public void deleteById(Long id) {
        Application application = findById(id);
        em.remove(application);
    }

谢谢。

一段时间后，我能够找到我的问题的解决方案，

ApplicationControllerTest.class

package com.spring.addapplication.test.controller;

import com.spring.addapplication.controller.ApplicationController;
import com.spring.addapplication.model.Application;
import com.spring.addapplication.service.ApplicationService;
import com.spring.addapplication.url.UrlChecker;

@RunWith(SpringJUnit4ClassRunner.class)
public class ApplicationControllerTest {

    @Mock
    ApplicationService applicationService;

    private MockMvc mockMvc;

    @Before
    public void setUp() throws Exception {
        initMocks(this);// this is needed for inititalization of mocks, if you use @Mock 
        ApplicationController controller = new ApplicationController(applicationService,urlChecker);
        mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
    }

    @Test
    public void deleteApplication() throws Exception {      
        Mockito.when(applicationService.removeById(10001L)).thenReturn("SUCCESS");
        mockMvc.perform(MockMvcRequestBuilders.delete("/applications", 10001L))
                .andExpect(status().isOk());
    }
