Spring Boot从入门到放弃-Spring Boot 整合测试

站长资讯摘要：
使用Spring Boot 整合测试，对Controller 中某个方法进行测试或者对Service,Mapper等进行测试，不需要运行项目即可查看运行结果是否和期望值相同，Spring Boot整合了Junit测试，对测试目标进行单元测试又方便了一步。

TestController:

package com.edu.usts.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
* Spring Boot整合测试
*/
@EnableAutoConfiguration
@Controller
public class TestController {

@RequestMapping("test")
@ResponseBody
public String test(){
return "test springboot";
}

public static void main(String[] args) {
SpringApplication.run(TestController.class,args);
}
}
这边返回测试值为 “test springboot”，后面我们使用TestCase.assertEquals()，对返回值和期望值之间进行比较。

正确案例：

package com.edu.usts.test;

import com.edu.usts.controller.TestController;
import junit.framework.TestCase;
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.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.security.RunAs;

/**
* Spring boot 整合测试
*/
@SpringBootTest(classes = TestController.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class TestSpringController {
@Autowired
private TestController testController;

@Test
public void test(){
TestCase.assertEquals(this.testController.test(),"test springboot");
}

}
运行截图:

绿色表示值对，则运行成功。我们修改测试值。

错误案例：

package com.edu.usts.test;

import com.edu.usts.controller.TestController;
import junit.framework.TestCase;
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.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.security.RunAs;

/**
* Spring boot 整合测试
*/
@SpringBootTest(classes = TestController.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class TestSpringController {
@Autowired
private TestController testController;

@Test
public void test(){
TestCase.assertEquals(this.testController.test(),"test");
}

}
运行截图：

返回显示目标值和期望值不同，则提示错误。

项目截图：

忽略某些Controller，仅看Controller:TestController.java和测试：TestSpringController.java
