Cool, do you have any example tests that do this?
Interesting, looks like pytest-twisted does away for the need for
this
by showing how to install a fake reactor globally:
https://github.com/pytest-dev/pytest-twisted/blob/master/pytest_twisted.py#L129-L142
What is 'fake' about this globally installed normally-the-default
reactor? (Otherwise the qt5reactor if chosen)
I guess I'm still not clear on what the point of using a 'fake' reactor
over a 'real' one is. Not that I'm an expert here...
Nothing, but the technique could be used to install a fake reactor
rather than having to change all the existing code to accept an
optional reactor parameter.
I use @pytest_twisted.inlineCallbacks anyways, yes.
Overall I'm not clear what was recommended here. Why fake the
reactor? Even if not using a 'real client' wouldn't you just fake the
data going through the connections rather than faking the entire
reactor?
I'd love to see some good example of faking the data going through the
connections, can you point me at some?
I would assume you would just write a 'client' in the test of whatever
complexity (could just write hardcoded byte sequences) which opens a
connection to the server and transmits the bytes and then asserts things
about the response. But no, I don't have any code. I can't say I have
a good test suite myself and I also don't actually use Twisted for
internet stuff (canbus and serial). Sorry. I would expect the servers
provided by Twisted would have their own tests you could look at though.
Cheers,
