Mockito - 我理解间谍调用对象的真实方法,而模拟调用双重对象的方法.除非有代码气味,否则还要避免间谍.但是,间谍是如何工作的,我应该什么时候真正使用它们?它们与模拟有何不同?
Mockito - I understand a spy calls the real methods on an object, while a mock calls methods on the double object. Also spies are to be avoided unless there is a code smell. However, how do spies work and when should i actually use them? How are they different from mocks?
从技术上讲,模拟"和间谍"都是一种特殊的测试替身".
Technically speaking both "mocks" and "spies" are a special kind of "test doubles".
不幸的是,Mockito 使这种区别变得很奇怪.
Mockito is unfortunately making the distinction weird.
mockito 中的模拟是其他模拟框架中的普通模拟(允许您存根调用;也就是说,从方法调用中返回特定值).
A mock in mockito is a normal mock in other mocking frameworks (allows you to stub invocations; that is, return specific values out of method calls).
mockito 中的间谍是其他模拟框架中的部分模拟(部分对象将被模拟,部分将使用真实的方法调用).
A spy in mockito is a partial mock in other mocking frameworks (part of the object will be mocked and part will use real method invocations).
