Integration tests for user auto-provision

[ngjunsiang]

Summary

Implement remaining integration tests for user auto-provisioning behavior during OAuth login flows. Test file scaffold exists but several tests are placeholders.

File

campus/tests/integration/auth/resources/test_user.py

Placeholder Tests to Implement

TestUsersResourceGetOrCreate class:

1. test_get_or_create_idempotent_multiple_calls (line 82-85)

   • Verify that multiple calls with same email return the same user record
   • Check that created_at timestamps remain consistent across calls

2. test_new_creates_user_with_activated_at (line 87-90)

   • Create user with explicit activated_at timestamp
   • Verify the timestamp is stored correctly

3. test_new_creates_user_without_activated_at (line 92-95)

   • Create user without activated_at
   • Verify the field is null/None

TestUserResource class:

4. test_activate_sets_activated_at (line 145-148)

   • Create a user without activated_at
   • Call activate() on the user resource
   • Verify activated_at is now set

5. test_delete_removes_user (line 150-153)

   • Create a user
   • Call delete() on the user resource
   • Verify user is removed (should raise NotFoundError on subsequent get)

Already Implemented

• ✅ test_get_or_create_creates_new_user_when_not_exists
• ✅ test_get_or_create_returns_existing_user_when_exists
• ✅ test_list_returns_all_users

Technical Notes

• Uses lazy imports to avoid storage initialization before test mode is configured (see AGENTS.md)
• Leverages campus.storage.testing for test storage configuration
• Tests cover the auto-provisioning flow used during OAuth login
