CLI端到端测试框架

为CLI应用程序设置端到端测试框架。

生成的模式

import { spawn, SpawnOptions } from 'child_process';

interface CLIResult {
  stdout: string;
  stderr: string;
  exitCode: number | null;
}

export async function runCLI(args: string[], options?: SpawnOptions): Promise<CLIResult> {
  return new Promise((resolve) => {
    const proc = spawn('node', ['./dist/index.js', ...args], {
      env: { ...process.env, NO_COLOR: '1' },
      ...options,
    });

    let stdout = '';
    let stderr = '';

    proc.stdout?.on('data', (data) => { stdout += data; });
    proc.stderr?.on('data', (data) => { stderr += data; });

    proc.on('close', (exitCode) => {
      resolve({ stdout, stderr, exitCode });
    });
  });
}

export function expectOutput(result: CLIResult) {
  return {
    toContain: (text: string) => expect(result.stdout).toContain(text),
    toMatchSnapshot: () => expect(result.stdout).toMatchSnapshot(),
    toExitWith: (code: number) => expect(result.exitCode).toBe(code),
  };
}
