[pytest-dev] Introspecting fixtures from within a test

[Raphael Pierzina]

Hi Christoph,

you can retrieve the used fixtures from the test node and use named function right after.

See https://gist.github.com/hackebrot/848ab671583540fe18d1 <https://gist.github.com/hackebrot/848ab671583540fe18d1>

Hope this helps!
Raphael
