MockMvc 的使用

用来快速模拟请求

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

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup(){
        //1.初始化
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }


    @Test
    public void whenUploadSuccess() throws Exception {
        //2.使用
        String reuslt = mockMvc.perform(MockMvcRequestBuilders.fileUpload("/file")
                .file(new MockMultipartFile("file","test.txt","multipart/form-data","hello word".getBytes())))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andReturn().getResponse().getContentAsString();

        System.out.println(reuslt);
    }

    @Test
    public void whenQuerySuccess() throws Exception {
        String result = mockMvc.perform(MockMvcRequestBuilders.get("/user")
                .param("username","jojo")
                .param("age","18")
                .param("ageTo","60")
                .param("size","15")
                .param("page","3")
                .param("sort","age,desc")
                //.content(content))  content为json字符串
                .contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.length()").value(3))
                .andReturn().getResponse().getContentAsString();
        System.out.println(result);
    }

}
