idea+SpringBoot单元测试

昨天研究框架异常的时候,想写个单元测试看看全局异常,结果出了点问题,觉得有必要记录一下

直接上图:

    1.在你要进行单元测试的方法所在类空白处右键,选择GO to → Test

2.选择新建一个单元测试类


3.勾选要生成的测试的方法,然后点击生成就可以

4.这样就会生成一个测试类,

5.加上注解,加上要测试的方法

package com.yz.system;

import com.yz.GunsApplication;
import com.yz.modular.system.model.MchAccnt;
import com.yz.modular.system.service.IMchAccntService;
import org.junit.After;
import org.junit.Before;
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;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = GunsApplication.class,webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class ExceptionTest {

    @Autowired
    private IMchAccntService mch;

    @Before
    public void before() throws Exception{
    }
    @After
    public void after() throws Exception {
    }

    @Test
    public void test() throws Exception {
        System.out.println("-------");
        MchAccnt dept = new MchAccnt();
        Object list = mch.selectMchAccnt(dept);
        System.out.println(list.toString());
    }
}

6.右键运行,输出

ps:期间遇到的坑,

一,

这里的GunsApplication是我们项目的启动类,如果单纯为Application,在没有注入其他bean的时候不会报错一旦注入就会报错;

二,

没有添加这行代码,始终提示找不到上下文,然后点进去看一下:

/**
 * Creates a (reactive) web application context without defining any
 * {@code server.port=0} {@link Environment} property.
 */
DEFINED_PORT(true),

三,关于@EnableAutoConfiguration这个注解,不加的话,右键运行单元测试也是可以的;

附上报错的截图:

Each configuration key has been temporarily mapped to its replacement for your convenience. To silence this warning, please update your configuration to use the new keys.
