We are now going to write and run our first end-to-end test with Playwright. Let’s start with a simple test, which just verifies that we have properly optimized our title for search engines. Follow these steps to write and run your first end-to-end test:

1. Create a new tests/seo.spec.js file. Inside this file, we are going to check whether the title of our page is set properly.

   test('has title', async ({ page }) => {
