🎭 Playwright Runner

⚠️ WARNING: For testing in production please refer to the Test runners document. This repository contains experimental work where we explore custom Jest runners and JSDom-alike component testing that uses real browsers.

Usage

1. npm i --save-dev jest playwright-runner or yarn add --dev jest playwright-runner
2. Specify playwright-runner in your Jest configuration:

// jest.config.js
module.exports = {
  "preset": "playwright-runner"
}

3. Place unit tests in files ending with .spec.* or .test.*.

// src/App.spec.jsx
import React from 'react';
import ReactDOM from 'react-dom';
import { App } from './App';

it('should work', function() {
  const container = document.createElement('div');
  ReactDOM.render(<App />, container);
  expect(container.textContent).toBe('Hello World');
});

4. Place end-to-end tests inside an e2e folder.

// e2e/basic.test.js
it('is a basic test with the page', async ({page}) => {
  await page.goto('https://github.com/microsoft/playwright-runner/blob/master/README.md');
  const title = await page.waitForSelector('article h1');
  expect(await title.textContent()).toBe('🎭 Playwright Runner');
});

5. Run all of your tests with npx jest or yarn jest
