# CLI Mock Stdin Create mock stdin utilities for testing. ## Generated Patterns ```typescript import { Readable } from 'stream'; export function mockStdin(inputs: string[]): Readable { let index = 0; return new Readable({ read() { if (index < inputs.length) { setTimeout(() => { this.push(inputs[index++] + '\n'); }, 10); } else { this.push(null); } }, }); } export async function runWithStdin( cmd: () => Promise<void>, inputs: string[] ): Promise<void> { const originalStdin = process.stdin; Object.defineProperty(process, 'stdin', { value: mockStdin(inputs) }); try { await cmd(); } finally { Object.defineProperty(process, 'stdin', { value: originalStdin }); } } ``` ## Target Processes - cli-unit-integration-testing - interactive-prompt-system
