junit.framework.AssertionFailedError: No tests found in **问题的解决-优快云博客

在学习AOP时，遇到JUnit测试错误：junit.framework.AssertionFailedError: No tests found。问题出在测试类的方法命名上，需将方法名从`transferTest()`改为`testTransfer()`，确保测试方法前缀为`test`，才能被JUnit识别。

今天在跟B站学习aop的过程中，想要编写测试类来测试自己的aop到底成不成功，于是编写测试类如下：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.itheima.service.IAccountService;

import junit.framework.TestCase;

public class testAccountService extends TestCase {
	ApplicationContext ac = new ClassPathXmlApplicationContext("bean.xml");
	IAccountService as = (IAccountService)ac.getBean("accountService");
	public void transferTest(){
		as.transfer("bbb", "aaa", 100);
	}

}

得到的报错结果如下：
junit.framework.AssertionFailedError: No tests found in com.itheima.test.testAccountService
at junit.framework.Assert.fail(Assert.java:47)
at junit.framework.TestSuite$1.runTest(TestSuite.java:263)

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

究其原因，在于测试类中的 public void transferTest()的命名出现问题。应该将transferTest()改为testTransfer()，将test前置，否则测试类将识别不出。
