🔑 WebAuthn passkeys

New Credentials virtual authenticator, available via browserContext.credentials, lets tests register passkeys and answer navigator.credentials.create() / navigator.credentials.get() ceremonies in the page — no real hardware key required, works in all browsers:

const context = await browser.newContext();

// Seed a passkey your backend provisioned for a test user.
await context.credentials.create('example.com', {
  id: credentialId,
  userHandle,
  privateKey,
  publicKey,
});
await context.credentials.install();

const page = await context.newPage();
await page.goto('https://example.com/login');
// The page's navigator.credentials.get() is answered with the seeded passkey.

You can also let the app register a passkey once in a setup test, read it back with credentials.get(), and seed it into later tests — see Credentials for details.

🗃️ Web Storage

New WebStorage API, available via page.localStorage and page.sessionStorage, reads and writes the page's storage for the current origin:

await page.localStorage.setItem('token', 'abc');
const token = await page.localStorage.getItem('token');
const items = await page.sessionStorage.items();

New APIs

Network

• apiResponse.securityDetails() and apiResponse.serverAddr() mirror the browser-side response.securityDetails() and response.serverAddr().

Browser and Screencast

• New option artifactsDir in browserType.connectOverCDP() controls where artifacts such as traces and downloads are stored when attached to an existing browser.
• New option cursor in screencast.showActions() controls the cursor decoration rendered for pointer actions.
• The onFrame callback in screencast.start() now receives a timestamp of when the frame was presented by the browser.

Test runner

• The testOptions.video option now supports the same set of modes as trace: new 'on-all-retries', 'retain-on-first-failure' and 'retain-on-failure-and-retries' values. See the video modes table for which runs are recorded and kept in each mode.
• Supported expect.soft.poll(...).
• New fullConfig.argv — a snapshot of process.argv from the runner process, handy for reading custom arguments passed after the -- separator.
• New fullConfig.failOnFlakyTests mirrors the config option, so reporters can explain why a flaky run failed.
• testInfo.errors now lists each sub-error of an AggregateError as a separate entry.
• New -G command line shorthand for --grep-invert.

🛠️ Other improvements

• Playwright now supports Ubuntu 26.04.
• HAR and trace recordings now include WebSocket requests.
