From 4253b71db9d8e38bf945d22f4246dcff387333a2 Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Fri, 28 Nov 2025 12:08:43 -0600 Subject: [PATCH] CLAUDE: Enhance WebSocket handlers with comprehensive test coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit WebSocket Infrastructure: - Connection manager: Improved connection/disconnection handling - Handlers: Enhanced event handlers for game operations Test Coverage (148 new tests): - test_connection_handlers.py: Connection lifecycle tests - test_connection_manager.py: Manager operations tests - test_handler_locking.py: Concurrency/locking tests - test_query_handlers.py: Game query handler tests - test_rate_limiting.py: Rate limit enforcement tests - test_substitution_handlers.py: Player substitution tests - test_manual_outcome_handlers.py: Manual outcome workflow tests - conftest.py: Shared WebSocket test fixtures 🤖 Generated with [Claude Code](https://claude.com/claude-code)
