class: Electron

  • langs: js

Playwright has experimental support for Electron automation. You can access electron namespace via:

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

An example of the Electron automation script would be:

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 (electron) => {
    // This runs in the main Electron process, |electron| parameter
    // here is always the result of the require('electron') in the main
    // app script.
    return electron.getAppPath();
  });

  // 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');
})();

Note that since you don't need Playwright to install web browsers when testing Electron, you can omit browser download via setting the following environment variable when installing Playwright:

$ PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm i -D playwright
