Failed to reference from session/module scope

[bcho]

Hi, it seems that the plugin fixtures' default scope is function, when I try to reference the fixture from a fixture with session scope, py.test will raise a ScopeMismatch error.

My use case is:

1. put a database schema init sql file to the data dir
2. add a fixture call init_db, which has session scope, and it will recreate the database schema only once during the whole test execution
3. init_db fixture use shared_datadir to read the init sql file

Any suggestions for this use case? Or can we change the plugin fixtures scope to session (or something else)?

After checking the code, it seems like the plugin requires reading dir from request.fspath, which is unavailable in session-scoped context... 😿

Hi @bcho,

datadir is meant to be used for every test.

For your use case, doesn't seem like you need datadir at all. Can't you use the builtin tmp_path_factory instead?

@nicoddemus Understood! I solved my problem by extracting from current working dir from __file__. Thanks for your help 👍
