Sourced from playwright's releases.

v1.57.0

Speedboard

In HTML reporter, there's a new tab we call "Speedboard":

It shows you all your executed tests sorted by slowness, and can help you understand where your test suite is taking longer than expected. Take a look at yours - maybe you'll find some tests that are spending a longer time waiting than they should!

Chrome for Testing

Starting with this release, Playwright switches from Chromium, to using Chrome for Testing builds. Both headed and headless browsers are subject to this. Your tests should still be passing after upgrading to Playwright 1.57.

We're expecting no functional changes to come from this switch. The biggest change is the new icon and title in your toolbar.

If you still see an unexpected behaviour change, please file an issue.

On Arm64 Linux, Playwright continues to use Chromium.

Waiting for webserver output

testConfig.webServer added a wait field. Pass a regular expression, and Playwright will wait until the webserver logs match it.

import { defineConfig } from '@playwright/test';
export default defineConfig({
webServer: {
command: 'npm run start',
wait: {
stdout: '/Listening on port (?<my_server_port>\d+)/'
},
},
});

If you include a named capture group into the expression, then Playwright will provide the capture group contents via environment variables:

import { test, expect } from '@playwright/test';
test.use({ baseUrl: http://localhost:${process.env.MY_SERVER_PORT ?? 3000} });
test('homepage', async ({ page }) => {
await page.goto('/');
});
</tr></table>
