Is there a way to get all fixtures names used by some test in pytest?

Question

Sometimes it's hard to understand why some fixture code is executed, while it seems should not. So I'd like to print all fixtures names, which will be resolved for some concrete test by pytest for more detailed analysis, is there such feature in pytest?

yes.

you could have a look at the output of these first:

pytest --fixtures          # show fixtures
pytest --fixtures -v       # show fixtures also with leading _
pytest --fixtures-per-test # show fixtures per test

if it was not enough, you might also check these out:

pytest --setup-only
pytest --setup-plan
