IMO mockito has a relatively good use experience. If you use MockitoExtension, especially, you write code that is relatively maintainable, and easy to mutate. The problem without MockitoExtension is you can throw all kinds of junk in there and it just sits there doing nothing, without you knowing it.

Spy's on the other hand, are a pain in the neck. I think they should be good in theory, but in practice they are difficult, the debuggers really don't work correctly, setting breakpoints, stepping, etc, is just broken in many cases. Would love to know if this is just a difficult bug, or something that is baked into spying.
