Getting Started with Playwright for React Testing on macOS

First, install Playwright. Run npm init playwright@latest in your terminal. This will prompt you to make some choices about your setup. Don't worry, Playwright has sensible defaults for most of these.

npm init playwright@latest

Playwright supports all modern rendering engines, including WebKit. However, it doesn't work with the branded version of Safari. So, you'll be testing against the recent WebKit build.

Next, you'll want to configure your project for testing with Playwright and React. Check out the "Experimental: components" section of the Playwright documentation for this.

Now, let's create a test file for your React app. Here's a simple test script you can use as a starting point:

import { test } from '@playwright/test';
import { expect } from 'chai';

test('basic test', async ({ page }) => {
  await page.goto('https://ray.run/');
  const title = await page.title();
  expect(title).to.equal('Ray');
});

You can also use beforeMount and afterMount hooks to set up things like an app router or fake server. This gives you more flexibility when testing.

In short, here's your game plan:

1. Install Playwright
2. Test against recent WebKit build
3. Configure your project for React
4. Use hooks for additional setup
