• Reactivate a user
• Search for users by name/email
• View user detail page
• Check notification delivery

Phase 2 - Course Management:

• Restore an archived course
• Create a new category
• Edit category name
• Attempt to delete category with courses (should fail)

Automated Tests

⏳ Playwright E2E tests will be added after manual testing validates all features.

Known Issues

Migration Connection Timeout
