Playwright v1.61.0 — Release Notes & Engineering Impact

## 🔑 WebAuthn passkeys New [Credentials](https://playwright.dev/docs/api/class-credentials) virtual authenticator, available via [browserContext.credentials](https://playwright.dev/docs/api/class-browsercontext#browser-context-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: ```js 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()](https://playwright.dev/docs/api/class-credentials#credentials-get), and seed it into later tests — see [Credentials](https://playwright.dev/docs/api/class-credentials) for details. ## 🗃️ Web Storage New [WebStorage](https://playwright.dev/docs/api/class-webstorage) API, available via [page.localStorage](https://playwright.dev/docs/api/class-page#page-local-storage) and [page.sessionStorage](https://playwright.dev/docs/api/class-page#page-session-storage), reads and writes the page's storage for the current origin: ```js await page.localStorage.setItem('token', 'abc'); const token = await page.localStorage.getItem('token'); const items = await page.sessionStorage.items(); ``` ## New APIs ### Network - [apiResponse.securityDetails()](https://playwright.dev/docs/api/class-apiresponse#api-response-security-details) and [apiResponse.serverAddr()](https://playwright.dev/docs/api/class-apiresponse#api-response-server-addr) mirror the browser-side [response.securityDetails()](https://playwright.dev/docs/api/class-response#response-security-details) and [response.serverAddr()](https://playwright.dev/docs/api/class-response#response-server-addr). ### Browser and Screencast - New option `artifactsDir` in [browserType.connectOverCDP()](https://playwright.dev/docs/api/class-browsertype#browser-type-connect-over-cdp) controls where artifacts such as traces and downloads are stored when attached to an existing browser. - New option `cursor` in [screencast.showActions()](https://playwright.dev/docs/api/class-screencast#screencast-show-actions) controls the cursor decoration rendered for pointer actions. - The `onFrame` callback in [screencast.start()](https://playwright.dev/docs/api/class-screencast#screencast-start) now receives a `timestamp` of when the frame was presented by the browser. ### Test runner - The [testOptions.video](https://playwright.dev/docs/api/class-testoptions#test-options-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](https://playwright.dev/docs/test-use-options#video-modes) for which runs are recorded and kept in each mode. - Supported `expect.soft.poll(...)`. - New [fullConfig.argv](https://playwright.dev/docs/api/class-fullconfig#full-config-argv) — a snapshot of `process.argv` from the runner process, handy for reading custom arguments passed after the `--` separator. - New [fullConfig.failOnFlakyTests](https://playwright.dev/docs/api/class-fullconfig#full-config-fail-on-flaky-tests) mirrors the config option, so reporters can explain why a flaky run failed. - [testInfo.errors](https://playwright.dev/docs/api/class-testinfo#test-info-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. ## Browser Versions - Chromium 149.0.7827.55 - Mozilla Firefox 151.0 - WebKit 26.5 This version was also tested against the following stable channels: - Google Chrome 149 - Microsoft Edge 149
