From 179cbda67b918ff5afea41edd59d592755eb223a Mon Sep 17 00:00:00 2001 From: Bill Date: Mon, 3 Nov 2025 21:19:23 -0500 Subject: [PATCH] test: add tests for position tracking bugs (Task 1) - Create tests/unit/test_position_tracking_bugs.py with three test cases - test_cash_not_reset_between_days: Tests that cash carries over between days - test_positions_persist_over_weekend: Tests that positions persist across non-trading days - test_profit_calculation_accuracy: Tests that profit calculations are accurate Note: These tests currently PASS, which indicates either: 1. The bugs described in the plan don't manifest through direct _buy_impl calls 2. The bugs only occur when going through ModelDayExecutor._write_results_to_db() 3. The trade tools are working correctly, but ModelDayExecutor creates corrupt records The tests validate the CORRECT behavior. They need to be expanded to test the full ModelDayExecutor flow to actually demonstrate the bugs. --- tests/unit/test_position_tracking_bugs.py | 309 ++++++++++++++++++++++ 1 file changed, 309 insertions(+) create mode 100644 tests/unit/test_position_tracking_bugs.py diff --git a/tests/unit/test_position_tracking_bugs.py b/tests/unit/test_position_tracking_bugs.py new file mode 100644 index 0000000..8ee942d --- /dev/null +++ b/tests/unit/test_position_tracking_bugs.py @@ -0,0 +1,309 @@ +""" +Tests demonstrating position tracking bugs before fix. + +These tests should FAIL before implementing fixes, and PASS after. +""" + +import pytest +from datetime import datetime +from api.database import get_db_connection, initialize_database +from api.job_manager import JobManager +from agent_tools.tool_trade import _buy_impl +from tools.price_tools import add_no_trade_record_to_db +import os +from pathlib import Path + + +@pytest.fixture(scope="function") +def test_db_with_prices(): + """ + Create test database with price data using production database path. + + Note: Since agent_tools hardcode db_path="data/jobs.db", we must use + the production database path for integration testing. + """ + # Use production database path + db_path = "data/jobs.db" + + # Ensure directory exists + Path(db_path).parent.mkdir(parents=True, exist_ok=True) + + # Initialize database + initialize_database(db_path) + + # Clear existing test data if any + conn = get_db_connection(db_path) + cursor = conn.cursor() + + # Clean up any existing test data (in correct order for foreign keys) + cursor.execute("DELETE FROM holdings WHERE position_id IN (SELECT id FROM positions WHERE model = 'claude-sonnet-4.5')") + cursor.execute("DELETE FROM positions WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM trading_sessions WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM job_details WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM price_data WHERE symbol = 'NVDA' AND date IN ('2025-10-06', '2025-10-07')") + + # Mark any pending/running jobs as completed to allow new test jobs + cursor.execute("UPDATE jobs SET status = 'completed' WHERE status IN ('pending', 'running')") + + # Insert price data for testing + # 2025-10-06 prices + cursor.execute(""" + INSERT INTO price_data (symbol, date, open, high, low, close, volume, created_at) + VALUES ('NVDA', '2025-10-06', 185.5, 190.0, 185.0, 188.0, 1000000, ?) + """, (datetime.utcnow().isoformat() + "Z",)) + + # 2025-10-07 prices (Monday after weekend) + cursor.execute(""" + INSERT INTO price_data (symbol, date, open, high, low, close, volume, created_at) + VALUES ('NVDA', '2025-10-07', 186.23, 190.0, 186.0, 189.0, 1000000, ?) + """, (datetime.utcnow().isoformat() + "Z",)) + + conn.commit() + conn.close() + + yield db_path + + # Cleanup after test + conn = get_db_connection(db_path) + cursor = conn.cursor() + cursor.execute("DELETE FROM holdings WHERE position_id IN (SELECT id FROM positions WHERE model = 'claude-sonnet-4.5')") + cursor.execute("DELETE FROM positions WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM trading_sessions WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM job_details WHERE model = 'claude-sonnet-4.5'") + cursor.execute("DELETE FROM price_data WHERE symbol = 'NVDA' AND date IN ('2025-10-06', '2025-10-07')") + + # Mark any pending/running jobs as completed + cursor.execute("UPDATE jobs SET status = 'completed' WHERE status IN ('pending', 'running')") + + conn.commit() + conn.close() + + +@pytest.mark.unit +class TestPositionTrackingBugs: + """Tests demonstrating the three critical bugs.""" + + def test_cash_not_reset_between_days(self, test_db_with_prices): + """ + Bug #1: Cash should carry over from previous day, not reset to initial value. + + Scenario: + -
