easymock求助

现在我要对TDDForInital类进行单体测试
代码如下：
public class TDDForInital {

public String returnStr(String str) {

if (null == str || str.length() < 3) {
return "";
}

return str.replaceAll(",", "-") + new A().a();
}
}

现在我想用easymock弄掉new A().a()方法

测试代码如下：
public class TestTDDForInital extends TestCase {

public void testReturnStr() {
A control = EasyMock.createMock(A.class);
control.a();
EasyMock.expectLastCall().andReturn("6");
EasyMock.replay(control);

TDDForInital t = new TDDForInital();
assertEquals("2006-03-036", t.returnStr("2006,03,03"));

EasyMock.verify(control);
}
}

为什么测试不通过啊？现象表明new A().a()方法根本没有被mock掉。

应该把你的Class A Mock以后set进TDDForInital中的returnStr方法里，而不是在returnStr方法里new 一个Class A
