3.2、整合 Playwright 生成 PDF

Playwright是由微软公司2020年初发布的新一代自动化测试工具，相较于目前最常用的 Selenium，它仅用一个API即可自动执行Chromium、Firefox、WebKit等主流浏览器自动化操作，并同时支持以无头模式、有头模式运行。

• 官方文档：https://playwright.dev/docs/api/class-electron
• GitHub：https://github.com/microsoft/playwright

引入 playwright

const { _electron } = require('playwright');

示例代码

const { _electron: electron } = require('playwright');

(async () => {
  // Launch Electron app.
  const electronApp = await electron.launch({ args: ['main.js'] });

  // Evaluation expression in the Electron context.
  const appPath = await electronApp.evaluate(async ({ app }) => {
    // This runs in the main Electron process, parameter here is always
    // the result of the require('electron') in the main app script.
    return app.getAppPath();
  });
  console.log(appPath);

  // Get the first window that the app opens, wait if necessary.
  const window = await electronApp.firstWindow();
  // Print the title.
  console.log(await window.title());
  // Capture a screenshot.
  await window.screenshot({ path: 'intro.png' });
  // Direct Electron console to Node terminal.
  window.on('console', console.log);
  // Click button.
  await window.click('text=Click me');
  // Exit app.
  await electronApp.close();
})();

请注意，由于测试 Electron 时不需要 Playwright 安装 Web 浏览器，因此您可以在安装 Playwright 时通过设置以下环境变量来省略浏览器下载：

PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm i -D playwright

支持的 Electron 版本有：

v12.2.0+
v13.4.0+
v14+
