"""Test suite for OAuth session context fix using FastMCP Client SDK to test the running MCP server."""
"""Test OAuth session context fixes and authentication improvements.
🔧 MCP Tools Used:
- OAuth authentication tools: Test OAuth flow improvements
- Session management: Test session context handling
- Authentication validation: Validate auth improvements
- Context preservation: Test context maintenance across requests
🧪 What's Being Tested:
- OAuth session context preservation and management
- Authentication state consistency across requests
- Session timeout and renewal mechanisms
- Context isolation between different user sessions
- Authentication error recovery and retry logic
- Session security and token management
- Integration with middleware authentication patterns
🔍 Potential Duplications:
- Authentication testing overlaps with auth pattern improvement tests
- Session management might overlap with other session-related tests
- OAuth flows similar to other authentication integration tests
- Context management patterns might be similar to other context-aware tests

"""
The fix addresses the issue where user email context was not being set
properly during OAuth authentication. The changes include:
1. **OAuth Callback (drive/upload_tools.py)**:
- Now stores user email in session data after successful OAuth
- Uses store_session_data(session_id, "user_email", user_email)
2. **Middleware (auth/middleware.py)**:
- on_request(): Restores user email context from session data
- on_call_tool(): First checks session data for user email before
extracting from tool arguments
3. **Result**:
- Resources like user://current/email now work after OAuth
- Session context persists across requests
- No need to pass user_email in every tool call
To test manually:
1. Start the server: python server.py
2. Authenticate via OAuth proxy
3. Access user://current/email - should return authenticated user
4. Access auth://session/current - should show user_email populated
