Expect

Last updated:
Reference:playwright.dev

Examples ​

Check if element exist (or not):

js
await expect(locator).toHaveCount(1); // YES exist
await expect(locator).toHaveCount(0); // NO don't exist

Using regex:

js
await expect(locator).toHaveText(/There are \d+ unread messages./u);

Take screenshot and expect it to be always the same:

js
await expect(page).toHaveScreenshot('home-screen.png');
