What are advanced features of pytest fixtures?

Advanced pytest fixtures allow for setup and teardown of resources, parameterization, and scope control.

Can you explain how to use fixture scopes?

Sure! Fixture scopes define how long a fixture lasts. Options include function, class, module, and session.

What is the difference between function and session scope?

Function scope means the fixture is created anew for each test, while session scope means it's created once per test session.

How can I share fixtures across multiple test files?

You can share fixtures by placing them in a conftest.py file, which pytest automatically recognizes.

Are there any best practices for using fixtures?

Yes, keep fixtures simple, avoid side effects, and use parameterization to reduce redundancy.
