/** * Terminal History Command Permutations E2E Tests * * This test suite validates different command permutations using the Terminal History * Testing Framework to ensure proper handling of pre-WebSocket and post-WebSocket commands * with exact assertions for: * - Command count verification (prompt counting) * - CRLF line ending validation (\r\n presence) * - Command echo verification (command appears after prompt) * - Result presence validation (output between commands) * - No concatenation detection (negative assertions) * - Proper SSH connection with keyFilePath * * Test Scenarios: * 1. Single Pre-WebSocket Command Only * 2. Multiple Pre-WebSocket Commands * 3. Single Post-WebSocket Command Only * 4. Balanced Pre/Post-WebSocket Commands * 5. Heavy Pre-WebSocket, Light Post-WebSocket Commands */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities'; describe('Terminal History Command Permutations E2E', () => { const testUtils = JestTestUtilities.setupJestEnvironment('terminal-history-command-permutations-e2e');
