From 6dae6d999a6024f2cbb01b1f605f69dec7057309 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 17:26:24 +0000 Subject: [PATCH 01/65] Add comprehensive tests to improve code coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add tests for core/simple_pg_logger.py (12.03% → 88.61% coverage) - Add tests for api/mexc.py (43.66% → 88.73% coverage) - Add tests for api/routes/dashboard.py These tests significantly improve coverage for critical low-coverage files. 48/49 tests passing for simple_pg_logger and mexc modules. ---

0502fb6fee5207a39d8be5d5bac77c8f6613ce84 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 17:41:59 +0000 Subject: [PATCH 02/65] Fix test failures and price formatting inconsistency **Tests fixes:** - Fix test_dashboard_routes.py (11 tests) - Properly mock verify_api_key using dependency_overrides - Fix TRADING_CONFIG patch (use config.TRADING_CONFIG) - Fix init_instances patch (use main.init_instances) - Fix test_get_status_exception with proper unserializable object - Fix test_set_socketio_with_ws_manager mock logic - Fix test_simple_pg_logger.py (1 test) - Fix reconnection test to properly simulate connection closing after error - Fix test_postgresql_datalogger.py (3 tests) - Add self.pool = None when PSYCOPG2_AVAILABLE is False - Skip obsolete tests (log_scan_error, log_market_context methods no longer exist) **Price formatting fix:** - Change 'tickSize' to 'tick_size' in position_manager.py to_dict() - Maintains consistency with Python snake_case convention - Frontend already handles both formats (tickSize || tick_size) - Fixes price decimal precision inconsistency between backend/frontend **Test results:** - 56 passed, 2 skipped - All critical functionality tests passing - Coverage improvements maintained --- core/position_manager.py | 2 +- core/postgresql_datalogger.py | 1 + tests/test_dashboard_routes.py | 106 +++++++++++++++-------------

scan continued running - WebSocket would restart with multiple symbols instead of staying on the position symbol - This caused current_price to freeze during active positions Solution: 1. scalability_refresh.py: Added check in _update_websocket() to prevent WebSocket changes when an active position exists 2. scanner_loop.py: After opening position, explicitly restart WebSocket with ONLY the position symbol to ensure price updates continue This ensures that during a position: - WebSocket stays focused on the position symbol only - current_price, TP, and SL prices update correctly
