This is the only library I've seen so far that allows testing sagas concurrent behaviour, instead of testing that your code is exactly what you wrote. The official docs on redux-saga recommend doing something useless, and most of the saga testing libraries out there follow the same pattern. Redux-saga-test-plan is useful instead. However, the API is counterintuitive and the docs could use more examples and redundancy. Everything is explained just once somewhere, and sometimes you have to re-read a page to find the detail you are looking for. I'm grateful for this amazing tool, and when I have time I will help improve it.
