Documentation on how to test

Hello,

I met Cristian at PyCon US (thanks, the open space, it was great). They encouraged us to post some pain points we might have with the QT for Python.

I'd love to have guidelines, best practices and examples on how to test a PySide application. Something I found was this: https://github.com/faaxm/spix. But I was maybe looking for something like Cypress (https://www.cypress.io/)?
