/** * SSH Banner and Command Positioning Diagnosis Test * * This test uses the Terminal History Testing Framework to diagnose the specific issues reported: * 1. SSH banners appearing in browser terminal history * 2. Commands appearing on separate lines from prompts instead of inline * * The test will capture actual WebSocket messages and analyze them for: * - SSH connection banners like "Activate the web console with..." * - Command positioning relative to prompts * - Terminal history content filtering */ import { JestTestUtilities } from './integration/terminal-history-framework/jest-test-utilities';
