[FEATURE] Fixtures similar to narwhal

[levouh]

Any plans to do something like this? The benefit of direct fixtures would be sharing them amongst tests and accessing them in an "easy" way (especially for those that are used to pytest). Beyond this, builtin setup and teardown functionality would also be nice to avoid things like calling these function manually in each test.

Hi, no, I have no plans on adding those right now because I don't need them. If it turns out many users requests them they will probably be added, given that they are intuitive and easy to use.
