/** * Command Extraction Debug Test * * PURPOSE: Debug why commands like "pwd" and "whoami" aren't appearing in concatenatedResponses * ISSUE: WebSocket messages are received and commands execute, but command strings don't get extracted * REGRESSION: Story6 test expects command strings to appear literally in concatenated output */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities'; describe('Command Extraction Debug', () => { const testUtils = JestTestUtilities.setupJestEnvironment('command-extraction-debug'); test('debug command extraction from WebSocket messages', async () => { console.log('\n=== COMMAND EXTRACTION DEBUG TEST ===\n'); const config = { preWebSocketCommands: [ 'ssh_connect {"name": "debug-session", "host": "localhost", "username": "jsbattig", "keyFilePath": "/home/jsbattig/.ssh/id_ed25519"}' ], postWebSocketCommands: [ {initiator: 'browser', command: 'pwd'} ], workflowTimeout: 30000, sessionName: 'debug-session' }; const result = await testUtils.runTerminalHistoryTest(config); console.log('\n=== DEBUG ANALYSIS ==='); console.log('SUCCESS:', result.success); console.log('ERROR:', result.error); console.log('CONCATENATED RESPONSES LENGTH:', result.concatenatedResponses.length); console.log('\n=== RAW CONCATENATED RESPONSES ==='); console.log(JSON.stringify(result.concatenatedResponses, null, 2)); console.log('\n=== INDIVIDUAL LINES ANALYSIS ==='); const lines = result.concatenatedResponses.split('\n'); lines.forEach((line, index) => { console.log(`Line ${index}: "${line}" (length: ${line.length})`); if (line.trim() === 'pwd') { console.log(` ✅ FOUND COMMAND: pwd at line ${index}`); } }); // Check for command presence with detailed debugging const commandOccurrences = result.concatenatedResponses .split('\n') .filter(line => { const trimmed = line.trim(); console.log(`Checking line: "${trimmed}" === "pwd" ? ${trimmed === 'pwd'}`); return trimmed === 'pwd'; }) .length; console.log('\n=== COMMAND SEARCH RESULTS ==='); console.log(`Command "pwd" occurrences: ${commandOccurrences}`); console.log(`Expected: 1, Actual: ${commandOccurrences}`); // Show what we actually got vs what we expected if (commandOccurrences === 0) { console.log('\n❌ COMMAND NOT FOUND - Analyzing possible causes:'); console.log('1.
