在项目开发中，测试环节是非常重要的，所以选择好的代码测试工具也显得尤为重要。
首先，基于前三篇的代码，先修改一些 Jar 包的版本，都用目前最新版本（强迫症！！！）。
junit 版本修改：3.8.1 -》 4.12
spring boot 版本修改：1.4.2.RELEASE -》 2.0.2.RELEASE
修改后 pom 文件如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>
<!-- 添加Spring Boot Devtools依赖包 -->

</project>一、使用 Junit 测试方法
创建 controller 包，并创建 TestController.java 测试类，代码如下：
package com.menglanglang.test.springboot.controller;
import org.junit.Test;
import org.springframework.web.bind.annotation.RestController;
/**
* @desc Controller测试类
*
* @author 孟郎郎
* @blog http://blog.csdn.net/tzhuwb
* @version 1.0
* @date 2018年5月26日上午8:14:53
*/
@RestController
public class TestController {
@Test
public void test() {
System.out.println("测试方法test()");
}
}右键 -》Run as -》 JUnit Test。
在控制台查看结果，输出为：
测试方法test()二、添加 spring-boot-starter-test 依赖包
在 pom 中添加依赖包，代码如下：
<!-- 添加 Spring Boot 测试依赖包 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<version>2.0.2.RELEASE</version>
<scope>test</scope>
</dependency>三、修改测试类 TestController.java
修改原测试类，添加 Spring Boot 注解，支持测试。
package com.menglanglang.test.springboot.controller;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.web.bind.annotation.RestController;
/**
* @desc Controller测试类
*
* @author 孟郎郎
* @blog http://blog.csdn.net/tzhuwb
* @version 1.0
* @date 2018年5月26日上午8:14:53
*/
@RestController
@RunWith(SpringRunner.class)
@SpringBootTest
public class TestController {
@Test
public void test() {
System.out.println("测试方法test()");
}
}在控制台查看结果，输出为：
