James, as you have posted several questions already wrt to pytest may i suggest
you rather subscribe and start posting to:
https://mail.python.org/mailman/listinfo/pytest-dev
Moreover, your examples so far contained some glitches which indicate you are
not that experienced with Python yet. That's totally fine but i suggest you
try to keep things as simple as you can before using all kinds of Python
features.
As to the mail below you can instantiate a class from a fixture and provide
that to a test:
class DoStuff():
def __init__(self, a,b):
self.a=a
self.b=b
def log(self, msg):
# do logging stuff
pass
@pytest.fixture
def do_stuff(a, b):
return DoStuff(a, b)
best,
holger
I still can't make it work:

______________________________ TestAclass.test_1

self = <testscript.TestAclass instance at 0x7f87395bffc8>

E NameError: global name 'do_stuff' is not defined

Is it a python error?
