JUnit Easymock Unexpected method call

junit methods call easymock

I'm trying to setup a test in JUnit w/ EasyMock and I'm running into a small issue that I can't seem to wrap my head around. I was hoping someone here could help.

Here is a simplified version of the method I'm trying to test:

public void myMethod() {
    //(...)
    Obj myObj = this.service.getObj(param);
    if (myObj.getExtId() != null) {
      OtherObj otherObj = new OtherObj();
      otherObj.setId(myObj.getExtId());
      this.dao.insert(otherObj);
    }
    //(...)
}

Ok so using EasyMock I've mocked the service.getObj(myObj) call and that works fine.

My problem comes when JUnit hits the dao.insert(otherObj) call. EasyMock throws a *Unexpected Method Call* on it.

I wouldn't mind mocking that dao in my test and using expectLastCall().once(); on it, but that assumes that I have a handle on the "otherObj" that's passed as a parameter at insert time... Which of course I don't since it's conditionally created within the context of the method being tested.

Anyone has ever had to deal with that and somehow solved it?

Thanks.

You could also use EasyMock.isA(OtherObj.class) for a little more type safety.
