在方法内创建模拟对象
如果我有以下方法：
public void handleUser(String user) {
User user = new User("Bob");
Phone phone = userDao.getPhone(user);
//something else
}
当我使用 EasyMock 进行模拟测试时，我是否可以像这样测试传递到 UserDao 模拟中的 User 参数：
User user = new User("Bob");
EasyMock.expect(userDaoMock.getPhone(user)).andReturn(new Phone());
当我尝试运行上述测试时，它会抱怨意外的方法调用我假设是因为该方法中创建的实际用户与我传入的用户不同......我对此是否正确？
或者我可以测试传递给 UserDao 的参数的最严格方法就是：
EasyMock.expect(userDaoMock.getPhone(EasyMock.isA(User.class))).andReturn(new Phone());
If I have the following method:
public void handleUser(String user) {
User user = new User("Bob");
Phone phone = userDao.getPhone(user);
//something else
}
When I'm testing this with mocks using EasyMock, is there anyway I could test the User parameter I passing into my UserDao mock like this:
User user = new User("Bob");
EasyMock.expect(userDaoMock.getPhone(user)).andReturn(new Phone());
When I tried to run the above test, it complains about unexpected method call which I assume because the actualy User created in the method is not the same as the one I'm passing in...am I correct about that?
Or is the strictest way I could test the parameter I'm passing into UserDao is just:
EasyMock.expect(userDaoMock.getPhone(EasyMock.isA(User.class))).andReturn(new Phone());

抛出意外的方法调用是正确的，因为
User对象在对getPhone的预期调用和实际调用之间是不同的。正如 @laurence-gonsalves 在评论中提到的，如果
User有一个有用的equals方法，您可以在预期对getPhone的调用应检查两个User对象是否相等。查看 EasyMock 文档，特别是“参数匹配器的灵活期望”部分。
You are correct that the unexpected method call is being thrown because the
Userobject is different between the expected and actual calls togetPhone.As @laurence-gonsalves mentions in the comment, if
Userhas a usefulequalsmethod, you could useEasyMock.eq(mockUser)inside the expected call togetPhonewhich should check that it the twoUserobject are equal.Have a look at the EasyMock Documentation, specifically in the section "Flexible Expectations with Argument Matchers".

我认为这应该可以解决您的问题。

I think this should solve your problem.
Yeswanth Devisetty 给出的答案稍作修改
EasyMock.expect(userDaoMock.getPhone(EasyMock.anyObject(User.class))).andReturn(new Phone());这将解决问题。
A little change in the answer given by Yeswanth Devisetty
EasyMock.expect(userDaoMock.getPhone(EasyMock.anyObject(User.class))).andReturn(new Phone());This will solve the problem.
