Test error handling (interrupt with Ctrl+C) -uv run python -m tests.load.oauth_benchmark -u 5 -d 60 -# Press Ctrl+C after a few seconds -# Verify cleanup still happens -``` - ---- - -## Known Limitations / TODOs - -1. **MCP Session Creation**: The `create_and_authenticate_user()` function returns `None` because MCP session creation with OAuth tokens is not yet implemented. This needs: - - Integration with `mcp.client.streamable_http` - - Passing OAuth token to MCP server - - Creating `UserSessionWrapper` with authenticated session - -2. **Workload Execution**: The benchmark doesn't run actual workloads yet - it just simulates the duration. Once MCP sessions are created, uncomment the workload execution code. - -3. **Parallel Optimization**: User creation is staggered by 2 seconds. This could be optimized based on server capacity. - -4. **Error Recovery**: If a user fails to authenticate, it's removed from the pool but the benchmark continues. Consider adding a minimum user threshold. - ---- - -## Summary - -The integration is ~80% complete: -- ā User pool management -- ā Dynamic user creation/deletion -- ā Playwright OAuth automation -- ā Callback server -- ā OAuth client registration -- ā CLI options -- ā Cleanup handlers -- ā ļø MCP session creation (placeholder) -- ā ļø Workload execution (depends on sessions) - -The framework is **production-ready** for user management and OAuth token acquisition. The final piece is connecting OAuth tokens to MCP sessions, which requires understanding how the MCP client handles OAuth authentication.
