Review

Goodbye Python. Hello Go.

介绍 Go 语言对比 Python 的优点。

Tip

编写针对RestfullAPI的测试用例，以前测试都是写一个Controller，构造一个形似/test/user的映射进行测试

package com.imooc.demo.web.controller;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserControllerTest {
    @Autowired
    private WebApplicationContext context;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
    }

    @Test
    public void whenQuerySuccess() throws Exception {
        mockMvc.perform(get("/user/query1")
                .contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk()) // 返回状态码为200
                .andExpect(jsonPath("$.length()").value(3));  // 返回数据的集合长度是3
    }

    @Test
    public void whenQuerySuccess2() throws Exception {
        mockMvc.perform(get("/user/query2")
                .param("username", "alex")
                .contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.length()").value(3));
    }

    @Test
    public void whenQuerySuccess3() throws Exception {
        mockMvc.perform(get("/user/query3")
                .param("username", "alex")

                .param("sort", "age,desc")
                .contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk()) // 返回状态码为200
                .andExpect(jsonPath("$.length()").value(3));  // 返回数据的集合长度是3
    }
}
