SpringBoot------单元测试

1.添加测试依赖

<dependency>
　　<groupId>org.springframework.boot</groupId>
　　<artifactId>spring-boot-starter-test</artifactId>
　　<scope>test</scope>
</dependency>

2.添加启动类和测试类

package top.ytheng.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication //等于下面3个
//@SpringBootConfiguration
//@EnableAutoConfiguration
//@ComponentScan
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

package top.ytheng.demo;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import junit.framework.TestCase;

//底层用junit SpringJunit4ClassRunner
@RunWith(SpringRunner.class)
//启动整个Springboot工程
@SpringBootTest(classes= {DemoApplication.class})
//鼠标选中SpringBootTestDemo后执行Run As -> JUnit Test可以同时执行多个测试
public class SpringBootTestDemo {
    @Test
    public void testOne() {
        System.out.println("test hello 1");
        TestCase.assertEquals(1, 1);
    }

    @Test
    public void testTwo() {
        System.out.println("test hello 2");
        TestCase.assertEquals(1, 1);
    }

    @Before
    public void testBefore() {
        System.out.println("test before");
    }

    //@Test之后调用
    //一般进行资源的回收利用
    @After
    public void testAfter() {
        System.out.println("test after");
    }
}

3.选中需要测试的方法，右键->Run AS->JUnit Test即可
