I am getting this too. I downgraded to pytest-bdd 2.16.0 and it worked fine. I am using Python 2.7.13 on Windows 10.

I've had a little look and the commit that causes this behaviour to begin for me is: be79c1d534634baeacddb1098e97988c9df8e9fb

I've had a little look and put in some debug. It looks like pytest registers the module under test during setup and then it gets registered again during pytest-bdd running...
