What is the difference between mock() and stub() when using Mockito?
提问by Tom
They both seem to do the same thing - why would you use one in preference to the other?
他们似乎都在做同样的事情——为什么你会优先使用另一个？
org.mockito.Mockito.stub()
org.mockito.Mockito.mock()

You can use a mock object to verify that you have called it in the way expected. In Mockito, mocked objects are automatically stubs, and verification occurs explicitly.
您可以使用模拟对象来验证您是否以预期的方式调用了它。在 Mockito 中，被模拟的对象是自动存根的，并且显式地进行验证。
From Mockito's "Why do we need another mocking framework?":
来自 Mockito 的“为什么我们需要另一个模拟框架？” ：
Separation of stubbing and verification. Should let me code in line with intuition:
stub before execution, selectively verify interactions afterwards. I don't
want any verification-related code before execution.
You can stub the behavior of calls before they're called. For example (from the Mockito home page):
您可以在调用之前对调用的行为进行存根。例如（来自 Mockito 主页）：
when( mockedList.get(0)).thenReturn( "first" );
You can verify interactions with mocked objects after they're called. For example:
您可以在调用后验证与模拟对象的交互。例如：
verify( mockedList ).add("one");
