Already imported module

Hey! I’m trying to migrate over my tests from nose to pytest to test my twisted application.

This site says: If a plugin is installed, pytest automatically finds and integrates it, there is no need to activate it. So according to this all I have to do is pip install pytest-twisted, but when I try running my tests I get: AttributeError: 'module' object has no attribute 'inlineCallbacks'

So on this site it says to put the following into conftest.py: pytest_plugins = "pytest_twisted" So I make conftest.py next to my testing Python file in the tests folder and get the following warning:

None
  Module already imported so can not be re-written: pytest_twisted

-- Docs: http://doc.pytest.org/en/latest/warnings.html

It seems like it auto discovers the plugin, but doesn’t update itself with inlinecallback without reimporting it? Would this be a bug, or just me not understanding something properly?

Any help is appreciated! Thank you!

Are you passing --twisted on the command line? I suggest to do that or add to the pytest.ini file:

[pytest]
twisted=1

Adding pytest_plugins to the conftest.py only works if you add it to your root conftest.py file. Anyway I suggest adding to pytest.ini as this is the simplest option IMHO.

Okay, thanks! I’ll bug them with my question.
