Springboot中进行测试

启动类

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

@SpringBootApplication
public class StartApplication {

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

}

测试类

1、 @SpringBootTest(classes = StartApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) 用来指定启动类
2、 @RunWith(SpringRunner.class) 指定用SpringRunner来运行

import mpTest.StartApplication;
import mpTest.entity.User;
import mpTest.mapper.UserMapper;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;

@SpringBootTest(classes = StartApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@RunWith(SpringRunner.class)
public class MPContextTest {

    @Test
    public void contextLoads() {
        System.out.println(("----- selectAll method test 测试查询所有用户方法 ------"));
        System.out.println("----------test--------------");
    }

}

关于InvalidTestClassError报错

测试报错

org.junit.runners.model.InvalidTestClassError: Invalid test class ‘XXX’:

1. No runnable methods

解决方案

• @Test导入错误,应该使用

import org.junit.Test;

• 声明未加public,应该使用

    @Test
    public void contextLoads() {
        
    }
