Hi Floris, all,
i think the below from an earlier thread is an outstanding issue for the
new API ...

With the current @setup API this is not possible but it should be. I'd like
to understand the exact use case a bit. What do you do with the "db"
object here? I guess you cause side effects because you would otherwise
just request a funcarg in the tests, right?
If so, then i can imagine the following solution:
@pytest.setup(enabled=myhelper)
def perform_side_effect_with(db):
...
The "enabled" helper would be called during collection so that
pytest gets to know which tests will actually execute the setup
function and its (potentially parametrized) required resources.
It could look like this::
def myhelper(collectioncontext):
return "needsdb" in collectioncontext.markers:
and collectioncontext also carries module/class/function (depending on
the scope specified with the setup). If the helper returns True then
the setup is considered and thus receives the DB object. Do you
think this would solve your use case? (Collectioncontext would not
have a addfinalizer() and might in the future offer more collection-specific
things).
best,
