v1.57.0

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.

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

• 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.expect_event() can be used to wait for it.
• locator.description() returns locator description previously set with locator.describe().
• New option steps in locator.click() and locator.drag_to() 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.

• New option --user-data-dir in multiple commands. You can specify the same user data dir to reuse browsing state, like authentication, between sessions.

        - link "Feature B":
          - /url: "https://playwright.dev"
  """)

Miscellaneous

• New option max_redirects in apiRequest.new_context() to control the maximum number of redirects.
• New option ref in locator.aria_snapshot() to generate reference for each element in the snapshot which can later be used to locate the element.

  # Save storage state into the file. Make sure to include IndexedDB.
  storage = context.storage_state(path="state.json", indexed_db=True)
  
  # Create a new context with the saved storage state.
  context = browser.new_context(storage_state="state.json")

• New option visible for locator.filter() allows matching only visible elements.

  # Ignore invisible todo items.
  todo_items = page.get_by_test_id("todo-item").filter(visible=True)
  # Check there are exactly 3 visible ones.
  expect(todo_items).to_have_count(3)

• New option contrast for methods page.emulate_media() and browser.new_context() allows to emulate the prefers-contrast media feature.

UI updates

• New button in Codegen for picking elements to produce aria snapshots.
• Additional details (such as keys pressed) are now displayed alongside action API calls in traces.
• Display of canvas content in traces is error-prone. Display is now disabled by default, and can be enabled via the Display canvas content UI setting.

Breaking

v1.49.0

Aria snapshots

New assertion expect(locator).toMatchAriaSnapshot() verifies page structure by comparing to an expected accessibility tree, represented as YAML.

page.goto("https://playwright.dev")
expect(page.locator('body')).to_match_aria_snapshot('''
  - banner:
    - heading /Playwright enables reliable/ [level=1]
    - link "Get started"
    - link "Star microsoft/playwright on GitHub"
  - main:
    - img "Browsers (Chromium, Firefox, WebKit)"
    - heading "Any browser • Any platform • One API"
''')

You can generate this assertion with Test Generator or by calling locator.ariaSnapshot().

Learn more in the aria snapshots guide.

Tracing groups

New method tracing.group() allows you to visually group actions in the trace viewer.

# All actions between group and group_end
# will be shown in the trace viewer as a group.
page.context.tracing.group("Open Playwright.dev > API")
page.goto("https://playwright.dev/")
page.get_by_role("link", name="API").click()
page.context.tracing.group_end()

Breaking: chrome and msedge channels switch to new headless mode

This change affects you if you're using one of the following channels in your playwright.config.ts:

• chrome, chrome-dev, chrome-beta, or chrome-canary
• msedge, msedge-dev, msedge-beta, or msedge-canary

After updating to Playwright v1.49, run your test suite. If it still passes, you're good to go. If not, you will probably need to update your snapshots, and adapt some of your test code around PDF viewers and extensions. See issue #33566 for more details.

Try new Chromium headless

You can opt into the new headless mode by using 'chromium' channel. As official Chrome documentation puts it:

New Headless on the other hand is the real Chrome browser, and is thus more authentic, reliable, and offers more features. This makes it more suitable for high-accuracy end-to-end web app testing or browser extension testing.

See issue #33566 for the list of possible breakages you could encounter and more details on Chromium headless. Please file an issue if you see any problems after opting in.

pytest test_login.py --browser-channel chromium
