Question about contribution

[Tusenka]

Intro:
I begin to learn project
Question:
Why here we take only fixturedefs args for the last parent?

pytest/src/_pytest/fixtures.py

Line 1599 in acf1303

for arg in fixturedefs[-1].argnames:

[RonnyPfannschmidt]

I believe that place is for finding the closest fixture definition

That's the last in the list

This plays a role for fixtures that expand an fixture of the same name
