springboot利用MockMvc测试controller控制器

主要记录一下控制器的测试，service这些类测试相对简单些（可测试性强）

API测试需求比较简单：

　　① 需要返回正确的http状态码 200

　　② 需要返回json数据，并且不能返回未经捕获的系统异常

测试不通过例子

此测试类的部分代码

    private MockMvc mockMvc;

    @Autowired
    protected WebApplicationContext wac;

    @Before()  //这个方法在每个方法执行之前都会执行一遍
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();  //初始化MockMvc对象
    }

    @Test

        mockMvc.perform(
                MockMvcRequestBuilders.get("/shopSearch").accept(MediaType.APPLICATION_JSON_UTF8)
                        .param("page", "1")

                        .param("goodsCategory", "1")
        )
                .andExpect(status().isOk())  // 判断返回状态
                .andExpect(content().contentType("application/json;charset=UTF-8")) // 判断内容类型
                .andExpect(jsonPath("$.code", Matchers.not(ErrorCodeMsgEnum.SYSTEM_ERROR.getCode()))) // 如果是系统异常（未捕获的异常），则测试不通过
                .andDo(print());  //打印出请求和相应的内容
    }
}
