springboot如何进行简单的测试

 一、pom文件添加spring-boot-starter-test依赖

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

二、项目可以正常启动(maven各包正常)

@SpringBootApplication
public class Application {

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

}

三、编写测试类

如下图位置新建你的测试类

 

添加注解，启动类的名称根据自己实际情况填写

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)

 根据需求，注入你需要的类，添加@Test注解，开始编写测试内容

package com.xxxxxx;

import com.xxxx.Application;
import com.xxxxxxm.util.RandomUtil;
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.SpringRunner;

@RunWith(SpringRunner.class)

@SpringBootTest(classes = Application.class)
public class UtilPay {
    @Autowired
    RandomUtil randomUtil;
    @Test
    public void util(){
        System.out.println(randomUtil.generateUpperString(6));
    }
}

 点击测试方法旁边启动按钮，进行测试，绿色表示正常

红色表示失败
