I think adding a e2e test for this would be good. I plan on doing it soon

I'm currently getting an issue when the progress deadline is reached but looking it.

@lmoroney Are we able to merge this? I see in the book the tf version is 2.0.0 but installing it seems a bit difficult. xD Or could we a requirements.txt?

This makes testing so much easier for socket io!
