I'm diving into my first serious PWB application. I'm using it as a library to replace mwclient.

I'm not sure how to approach testing. I'd really like something which is isolated from making actual API calls (i.e. hermetic unit tests). Does there exist a mechanism to do that?

What I've been doing so far is using unittest.mock to create mock Page objects, but that's not wondeful. unitest.mock is always a little clunky to use, but more than that, it's too easy to create mocks that don't accurately emulate the real PWB behaviors, so your tests aren't really testing what they should be. The other problem is if you don't mock every possible code path to the backend API, you can end up hitting a real server by accident during your tests. Which we be not a good thing.

How do people handle this?
