Spring Boot 编写Mock测试

引入Maven依赖：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

测试Controller的代码

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

    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

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

     @Test
    public void testTes() throws Exception{
        mockMvc.perform(MockMvcRequestBuilders.get("/api/test") // 发出请求
                .contentType(MediaType.APPLICATION_JSON_UTF8) //期望的内容类型
                .accept(MediaType.APPLICATION_JSON_UTF8)) //期望接收的内容类型
                .andExpect(MockMvcResultMatchers.status().isOk()) //期望结果是200
                .andDo(MockMvcResultHandlers.print()); // 期望把结果打印出来
     }
}

Mock测试打印输出的日志：
