Spring Boot Web项目RESTful API 与单元测试

1、idea新创建Spring Boot项目，选择Web类型

2、增加HelloController类，代码如下

<pre class="prettyprint linenums" >
package com.example.demo;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockServletContext;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.mock.web.MockBodyContent;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

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

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = MockServletContext.class)
//@WebAppConfiguration

public class Chapter1ApplicationTests {

private MockMvc mvc;

@Before
public void setUp() throws Exception {
mvc = MockMvcBuilders.standaloneSetup(new HelloController()).build();
}

@Test
public void getHello() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().string(equalTo("Hello World")));
}

}

</pre>
3、启动项目访问hello，输出页面内容hello world,不得不说现在技术变化真快，比以前省事多了

4、编写测试单元，创建Chapter1ApplicationTests测试类，代码如下
<pre class="prettyprint linenums" >
package com.example.demo;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockServletContext;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.mock.web.MockBodyContent;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

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

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = MockServletContext.class)
//@WebAppConfiguration

public class Chapter1ApplicationTests {

private MockMvc mvc;

@Before
public void setUp() throws Exception {
mvc = MockMvcBuilders.standaloneSetup(new HelloController()).build();
}

@Test
public void getHello() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().string(equalTo("Hello World")));
}

}
</pre>
5、运行测试getHello类，查看测试结果
