New version of pytest-bdd requires some updates

[rnwolf]

Hi

When using pytest-bdd==3.2.1
as seen in article in http://www.datio.com/bbdd/behavior-driver-development-with-python-a-humble-introduction/
I can get pytest passing for file step_1/tests/test_serving.py

but when using the current pytest-bdd version 4.0.2 I get an error. Something has changed, most probably trival for you to update, but unfortunately I am not at that level of understanding yet.

Any tips on what I could do to get your example working with the 4.x versions of pytest-bdd?

It seems that the current version @given requires one to specify a , target_fixture= but I then start to go down a rabbit hole.
