本文介绍了一个简单的Java单元测试框架实现，通过注解@Testable标记的方法将被自动执行并报告测试结果，展示了基本的测试流程及异常处理。

ProcessorTest.java

package br.com.waslleysouza.zz;

import java.lang.reflect.Method;

public class ProcessorTest {
public ProcessorTest() {
super();
}
public static void process(String clazz) throws ClassNotFoundException
{
int passed = 0;
int failed = 0;

for(Method m : Class.forName(clazz).getMethods())
{
if(m.isAnnotationPresent(Testable.class))
{
try
{
m.invoke(null);
passed++;
}
catch(Exception ex)
{
System.out.println("方法"+m+"运行失败,异常:"+ex.getCause());
failed++;
}
}
}
System.out.println("共运行了:"+(passed+failed)+"个方法,其中:\n"+"失败了:"+failed+"个,\n"+"成功了:"+passed+"个！");
}
}

-----------------------------------

MyTest.java

package br.com.waslleysouza.zz;

public class MyTest {
public MyTest() {
super();
}
@Testable
public static void m1()
{}
public static void m2()
{}
@Testable
public static void m3()
{
throw new IllegalArgumentException("参数出错了！");
}
public static void m4()
{

}
@Testable
public static void m5()
{

}
public static void m6()
{

}
@Testable
public static void m7()
{
throw new IllegalArgumentException("程序业务出现异常");
}
public static void m8()
{
}

}

-------------------------Testable.java------------------------

package br.com.waslleysouza.zz;

import java.lang.annotation.*;

}
