Compatibility issue with Pydantic v2 - TypeError on CoreSettings.default_database_config()

[francbartoli]

Description

When using pytest-iam with Pydantic v2, an error occurs during fixture initialization.

Environment

• Python: 3.12
• Pydantic: 2.x
• pytest-iam: latest

Error

TypeError: CoreSettings.default_database_config() missing 1 required positional argument: 'self'

Steps to Reproduce

1. Install pytest-iam in a project using Pydantic v2
2. Use the iam fixture in a test
3. Run pytest

Expected Behavior

The iam fixture should initialize correctly and provide a mock OIDC server.

Actual Behavior

The fixture fails with a TypeError because default_database_config is being called as a class method instead of an instance method.

Related

This appears to be related to Pydantic v2 migration issues. See: pydantic/pydantic#10551

Workaround

Currently using mocked OIDC authentication directly instead of pytest-iam.

Hi. I am using pytest-iam in projects using Pydantic 2 without issue. The unit tests indirectly install Pydantic and run fine too.
What Pydantic version exactly do you use?

Ah. I think this may have been fixed by yaal-coop/canaille@d1c331b in Canaille 0.1.0
What version of Canaille do you use?
