Here's the original pytest issue this links back to:

pytest-dev/pytest#3661

I think the warning is a result of the datapath fixture which is called directly as a function in various setup_methods in the test_sql module

[alimcmaster1]

I think this is an example of an offending line iris_csv_file = datapath('io', 'data', 'iris.csv') ? Im happy to take a look at refactoring this, unless anyone else has already started looking?

[WillAyd]

@alimcmaster1 go for it!

[alimcmaster1]

Sorry for the delay @WillAyd just put a PR out for this now. Let me know what you guys think
