公司的产品要引入单元测试以及代码覆盖，让我做一个框架方便我们写单元测试代码，上网找了一下，找到一个不错的基础：MockEJB，大家可以先了解下相关的内容：
MockEJB项目简介信息
使用MockEJB简化EJB测试
我在这个基础上进行了扩充，框架具有如下的特性：
- 读取EJB配制文件完成EJB的自动发布，框架会读取我们工程的ejb-jar.xml，jboss.xml，jbosscmp- jdbc.xml文件的配制信息并组合这些信息完成自动发布所需要的内容。
- 共享的dummy数据，我们自己提供一个xml文件，里面存放一些dummy的数据，这些数据会在对应的Entity Bean被使用的时候自动插入数据库，完成数据的初始化工作（这样Session Bean中的SQL也可以取到一致的内容），在一个test方法结束的时候回滚，删除那些记录，消除Test Case之间的影响。
- 自定义事务管理，每个test方法都处于同一个事务中，方法结束的时候事务回滚，消除Test Case之间的影响。
- 支持部分find方法的实现，由于MockEJB对于Entity Bean只提供了对findByPrimaryKey的支持，甚至连findAll都不支持，框架在MockEJB提供的Aspect机制的基础上实现了 findAll等常用必备的find方法，并且对于自定义的find方法也提供部分支持，通过解析EJB配制文件中的SQL完成，但是可能性能不好，因为会遍历所有的记录并比较字段的值完成这个查找的过程。其它比较复杂的find方法（框架无法解析的SQL），需要自己实现对应的Aspect，框架会自动查找对应的Aspect。
- 在Struts TestCase的基础上支持对Action的单元测试。
测试代码范例：
测试Action
package com.xxx.test.action;
import java.util.List;
import com.xxx.controller.util.Team;
import com.xxx.test.base.BaseActionTestCase;
public class TestListAllPersonsAction extends BaseActionTestCase {
public TestListAllPersonsAction(String testName) {
super(testName);
}
public void testSuccessful() throws Exception {
setRequestPathInfo("/ListAllPersons.do");
actionPerform();
verifyForward("success");
List persons = (List) getRequest().getAttribute("PERSON_LIST");
assertEquals(9, persons.size());
Team team = (Team) getRequest().getAttribute("TEAM");
assertNotNull(team);
}
}
测试Session Bean：
package com.xxx.test.ejb;
import java.util.ArrayList;
import java.util.List;
import com.xxx.common.data.CrystalReportConfigValueObj;
