Testing of two ways springboot

2019 Unicorn Enterprises heavily recruiting engineers Python standard >>>

1, controller class code

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        return "hello world!";
    }
}

 

2, the test class code, including the introduction of the class

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
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.request.MockMvcRequestBuilders;

import static org.hamcrest.CoreMatchers.equalTo;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;


// 第一种方式，推荐这种使用更方便
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc

// 第二种方式@WebMvcTest中的参数需要填你要测试的controller类，而不是Application.class
//@RunWith(SpringRunner.class)
//@WebMvcTest(HelloController.class)
public class HelloControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testHello() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("hello world!")));
    }
}
