CLI 模拟标准输入

为测试创建模拟标准输入实用工具。

生成的模式

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++] + '
');
        }, 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 });
  }
}
