FIX: make azure-core import optional in test_008_auth.py

[Jahnvi Thakkar (jahnvi480)]

AB#46836

Summary

tests/test_008_auth.py added a top-level from azure.core.credentials import TokenCredential (introduced with the token_provider work in #603). That import runs at module-collection time — before the autouse setup_azure_identity fixture injects its mock azure.* modules into sys.modules — so in build/validation stages that install a minimal dependency set (no azure-identity/azure-core), pytest aborts the whole module with:

ModuleNotFoundError: No module named 'azure'
  tests/test_008_auth.py:32: in <module>
    from azure.core.credentials import TokenCredential

This wraps only that one top-level import in a try/except ImportError guard (falling back to TokenCredential = None) so the module collects even when azure-core is absent. The two tests in TestTokenProviderProtocol that genuinely need the real runtime_checkable Protocol are marked @pytest.mark.skipif(TokenCredential is None, ...); the third scope-constant test does not use TokenCredential and continues to run.

All other azure.* imports in this file are function-local and already resolve to the fixture's sys.modules mocks, so no other changes are needed. When azure-core is installed (the normal path), behavior is unchanged and both protocol tests run.

No production code is touched — test-only hardening.

🟢 Ready to approve

The change is a small, test-only guard that prevents collection-time failures without altering production behavior.

Pull request overview

This PR hardens the tests/test_008_auth.py module collection path by making the azure-core dependency optional at import time, preventing pytest from aborting in minimal dependency environments (no azure packages installed) while preserving existing behavior when azure-core is available.

Changes:

• Wrapped the top-level from azure.core.credentials import TokenCredential import in a try/except ImportError, falling back to TokenCredential = None.
• Marked the two TokenCredential Protocol runtime-check tests with @pytest.mark.skipif(TokenCredential is None, ...) so they only run when azure-core is installed.
