## UI Mode Updates ![Playwright UI Mode](https://github.com/microsoft/playwright/assets/746130/8ba27be0-58fd-4f62-8561-950480610369) 1. Zoom into time range. 2. Network panel redesign. ## New APIs - [`browserContext.on('weberror')`] - [`locator.pressSequentially()`] - The [`reporter.onEnd()`] now reports `startTime` and total run `duration`. ## Deprecations - The following methods were deprecated: [`page.type()`], [`frame.type()`], [`locator.type()`] and [`elementHandle.type()`]. Please use [`locator.fill()`] instead which is much faster. Use [`locator.pressSequentially()`] only if there is a special keyboard handling on the page, and you need to press keys one-by-one. ## Breaking Changes: Playwright no longer downloads browsers automatically > [!NOTE] > If you are using `@playwright/test` package, this change **does not** affect you. Playwright recommends to use `@playwright/test` package and download browsers via `npx playwright install` command. If you are following this recommendation, nothing has changed for you. However, up to v1.38, installing the `playwright` package instead of `@playwright/test` did automatically download browsers. This is no longer the case, and we recommend to explicitly download browsers via `npx playwright install` command. **v1.37 and earlier** `playwright` package was downloading browsers during `npm install`, while `@playwright/test` was not. **v1.38 and later** `playwright` and `@playwright/test` packages do not download browsers during `npm install`. **Recommended migration** Run `npx playwright install` to download browsers after `npm install`. For example, in your CI configuration: ```yml - run: npm ci - run: npx playwright install --with-deps ``` **Alternative migration option - not recommended** Add `@playwright/browser-chromium`, `@playwright/browser-firefox` and `@playwright/browser-webkit` as a dependency. These packages download respective browsers during `npm install`. Make sure you keep the version of all playwright packages in sync: ```json5 // package.json { "devDependencies": { "playwright": "1.38.0", "@playwright/browser-chromium": "1.38.0", "@playwright/browser-firefox": "1.38.0", "@playwright/browser-webkit": "1.38.0" } } ``` ### Browser Versions * Chromium 117.0.5938.62 * Mozilla Firefox 117.0 * WebKit 17.0 This version was also tested against the following stable channels: * Google Chrome 116 * Microsoft Edge 116 [`browserContext.on('weberror')`]: https://playwright.dev/docs/api/class-browsercontext#browser-context-event-web-error [`locator.pressSequentially()`]: https://playwright.dev/docs/api/class-locator#locator-press-sequentially [`reporter.onEnd()`]: https://playwright.dev/docs/api/class-reporter#reporter-on-end [`page.type()`]: https://playwright.dev/docs/api/class-page#page-type [`frame.type()`]: https://playwright.dev/docs/api/class-frame#frame-type [`locator.type()`]: https://playwright.dev/docs/api/class-locator#locator-type [`elementHandle.type()`]: https://playwright.dev/docs/api/class-elementhandle#element-handle-type [`locator.fill()`]: https://playwright.dev/docs/api/class-locator#locator-fill [`expect(value).toMatchSnapshot()`]: https://playwright.dev/docs/api/class-snapshotassertions#snapshot-assertions-to-match-snapshot-1 [`expect(page).toHaveScreenshot()`]: https://playwright.dev/docs/api/class-pageassertions#page-assertions-to-have-screenshot-1 [`expect(locator).toHaveScreenshot()`]: https://playwright.dev/docs/api/class-locatorassertions#locator-assertions-to-have-screenshot-1
