SpringBoot Test集成测试(service层)

如何测试SpringBoot的请求?使用spring-boot-starter-test这个包即可完成测试

1、在src/test/main目录下编写测试类AccountBasicServiceImplTest.java

package cn.yunpay.account.service.impl;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import cn.yunpay.account.service.AccountServiceBootStart;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes=AccountServiceBootStart.class)
@EnableAutoConfiguration
public class AccountBasicServiceImplTest {

	@Autowired
	AccountBasicServiceImpl accountBasicServiceImpl;
	
	@Test
	public void testAddBaseAccount() {
		accountBasicServiceImpl.addBaseAccount("", "");
	}

}

2、运行项目

日志报错：

出现此错误一般是jar包冲突，我父项目里引了版本管理spring-core.jar。子项目里没有引用，但是启动的时候会扫描你所有包。

此处将spring-core.jar包删除掉就可以了。

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-core</artifactId>
	<version>5.0.5.RELEASE</version>
</dependency>
