easymock中遇到方法调用次数错误的问题

一个测试，测试两个动作见 *1， *2

public void testVoteCheck() throws Exception {

// *1 测试找不到结果，返回true
mockVoteDao.getVote("192.168", 1);

EasyMock.expectLastCall().andReturn(null);

EasyMock.replay(mockVoteDao);

boolean result = voteService.voteCheck(vote);

assertTrue(result);

// *2 测试找到结果但小于半小时
mockVoteDao.getVote("192.168", 1); //xxxxxxxx

EasyMock.expectLastCall().andReturn(vote);

EasyMock.replay(mockVoteDao);

boolean result = voteService.voteCheck(vote);

assertFalse(result);


}

结果报错
java.lang.AssertionError:
Unexpected method call getVote("192.168", 1):
getVote("192.168", 1): expected: 1, actual: 1 (+1)
at org.easymock.internal.MockInvocationHandler.invoke(MockInvocationHandler.java:29)
at org.easymock.internal.ObjectMethodsFilter.invoke(ObjectMethodsFilter.java:45)

在运行完 //xxxxxxxx行就出错了
意思是说预计mockVoteDao.getVote("192.168", 1);只调用一次,结果调用了两次,
也就是说一旦一个mock对象被激活,并且没有被设定调用多次的话,会抛错

但如果用以下方式就没错
/**
* 测试保存投票前的检查
*
* @author weip
* @time 2006-5-12 12:10:00
* @throws Exception a
*/
public void testVoteCheck() throws Exception {

// 测试找不到结果，返回true
mockVoteDao.getVote("192.168", 1);

EasyMock.expectLastCall().andReturn(null);

EasyMock.replay(mockVoteDao);

boolean result = voteService.voteCheck(vote);

assertTrue(result);

}

/**
* 测试找到结果但小于半小时
* @author weip
* @time 2006-5-12 15:16:23
* @throws Exception a
*/
public void testVoteCheck2() throws Exception {
mockVoteDao.getVote("192.168", 1);

EasyMock.expectLastCall().andReturn(vote);

EasyMock.replay(mockVoteDao);

boolean result = voteService.voteCheck(vote);

assertFalse(result);
}

即将一个方法拆成两个就没错,因为这个时候两个测试中mockVoteDao是不同的对象
