Playwright Release Notes

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('/');
});

This is not just useful for capturing varying ports of dev servers. You can also use it to wait for readiness of a service that doesn't expose an HTTP readiness check, but instead prints a readiness message to stdout or stderr.

Breaking Change

After 3 years of being deprecated, we removed Page#accessibility from our API. Please use other libraries such as Axe if you need to test page accessibility. See our Node.js guide for integration with Axe.

New APIs

New property testConfig.tag adds a tag to all tests in this run. This is useful when using merge-reports.
worker.on('console') event is emitted when JavaScript within the worker calls one of console API methods, e.g. console.log or console.dir. worker.waitForEvent() can be used to wait for it.
locator.description() returns locator description previously set with locator.describe(), and Locator.toString() now uses the description when available.
New option steps in locator.click() and locator.dragTo() that configures the number of mousemove events emitted while moving the mouse pointer to the target element.
Network requests issued by Service Workers are now reported and can be routed through the BrowserContext, only in Chromium. You can opt out using the PLAYWRIGHT_DISABLE_SERVICE_WORKER_NETWORK environment variable.
Console messages from Service Workers are dispatched through worker.on('console'). You can opt out of this using the PLAYWRIGHT_DISABLE_SERVICE_WORKER_CONSOLE environment variable.

Browser Versions

• Mozilla Firefox 144.0.2
• WebKit 26.0

Playwright Agents

Introducing Playwright Agents, three custom agent definitions designed to guide LLMs through the core process of building a Playwright test:
🎭 planner explores the app and produces a Markdown test plan
🎭 generator transforms the Markdown plan into the Playwright Test files
🎭 healer executes the test suite and automatically repairs failing tests

Run npx playwright init-agents with your client of choice to generate the latest agent definitions:

• Generate agent files for each agentic loop
  • Visual Studio Code

    npx playwright init-agents --loop=vscode
    

  • Claude Code

    npx playwright init-agents --loop=claude
    

  • opencode

    npx playwright init-agents --loop=opencode
    

  Note
  VS Code v1.105 (currently on the VS Code Insiders channel) is needed for the agentic experience in VS Code. It will become stable shortly, we are a bit ahead of times with this functionality!
