/** * Terminal Display Issue Diagnosis Test * * This test uses the Terminal History Testing Framework to diagnose the specific * terminal display issues reported by the user: * * ISSUES: * 1. Commands appear on wrong line (separated from prompt) * 2. Prompt corruption (missing characters like "[j") * * EXPECTED BEHAVIOR: * - Commands should appear inline with prompts: [user@host ~]$ command * - Complete, uncorrupted prompts should be preserved * - No empty prompt lines should appear * * This test will capture actual WebSocket messages to identify root causes. */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities'; describe('Terminal Display Issue Diagnosis', () => { const testUtils = JestTestUtilities.setupJestEnvironment('terminal-display-diagnosis'); // Extend Jest with custom matchers beforeAll(() => { JestTestUtilities.extendJestMatchers(); }); test('should diagnose terminal display issues for restarted-test session with date command', async () => { console.log('=== TERMINAL DISPLAY DIAGNOSIS TEST ==='); console.log('Testing session: restarted-test'); console.log('Command to test: date'); console.log('Expected: [jsbattig@localhost ~]$ date (inline)'); console.log('Problem: Command appears on separate line + prompt corruption'); // Configure test to replicate the exact scenario const config = { preWebSocketCommands: [ // Connect to localhost with SSH key authentication 'ssh_connect {"name": "restarted-test", "host": "localhost", "username": "jsbattig", "keyFilePath": "/home/jsbattig/.ssh/id_ed25519"}', // Execute the problematic date command 'ssh_exec {"sessionName": "restarted-test", "command": "date"}' ], postWebSocketCommands: [ // Execute another command to see if the issue persists 'ssh_exec {"sessionName": "restarted-test", "command": "whoami"}' ], workflowTimeout: 30000, sessionName: 'restarted-test' }; console.log('=== EXECUTING FRAMEWORK TEST ==='); const result = await testUtils.runTerminalHistoryTest(config); console.log('=== TEST EXECUTION RESULTS ==='); console.log(`Success: ${result.success}`); console.log(`Total execution time: ${result.totalExecutionTime}ms`); console.log(`WebSocket messages captured: ${result.concatenatedResponses.length} characters`); // Log the actual WebSocket messages for analysis console.log('\n=== RAW WEBSOCKET MESSAGES (for diagnosis) ==='); console.log('BEGIN WEBSOCKET DATA:'); console.log(JSON.stringify(result.concatenatedResponses, null, 2)); console.log('END WEBSOCKET DATA'); console.log(''); // Log each line separately for detailed analysis console.log('=== LINE-BY-LINE ANALYSIS ==='); const lines = result.concatenatedResponses.split('\n'); lines.forEach((line, index) => { console.log(`Line ${index + 1}: "${line}"`); // Check for specific issues if (line.includes('date') && !line.includes('$')) { console.log(` ❌ ISSUE DETECTED: Command "date" appears without prompt on same line`); } if (line.includes('@') && line.includes('$')) { if (line.startsWith('sbattig@') || line.includes('sbattig@') && !line.includes('[jsbattig@')) { console.log(` ❌ ISSUE DETECTED: Prompt corruption - missing "[j" character`); } if (line.includes('[jsbattig@localhost ~]$')) { console.log(` ✅ CORRECT: Complete bracket format prompt found`); } } if (line.trim() === '' && index > 0 && lines[index - 1].includes('$')) { console.log(` ❌ ISSUE DETECTED: Empty line after prompt`); } }); // Validate using framework assertions console.log('\n=== FRAMEWORK VALIDATION ==='); try { testUtils.expectWebSocketMessages(result.concatenatedResponses) .toContainCRLF() .toHavePrompts() .toMatchCommandSequence(['date', 'whoami']) .toHaveMinimumLength(10) .validate(); console.log('✅ All basic framework validations passed'); } catch (validationError) { console.log('❌ Framework validation failures:'); console.log(validationError); } // Custom validations for the specific issues console.log('\n=== SPECIFIC ISSUE VALIDATION ==='); // Check for inline command display (commands should appear on same line as prompt) const promptWithDatePattern = /\[jsbattig@localhost[^\]]*\]\$\s+date/; const hasInlineDate = promptWithDatePattern.test(result.concatenatedResponses); console.log(`Inline date command: ${hasInlineDate ?
