Update playwright requirement from <1.46 to <1.50

[dependabot]

Updates the requirements on playwright to permit the latest version.

Release notes

Sourced from playwright's releases.

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](microsoft/playwright#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](microsoft/playwright#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.
