Release notes

Version 1.15#

🎭 Playwright Library#

🖱️ Mouse Wheel#

By using Page.mouse.wheel you are now able to scroll vertically or horizontally.

📜 New Headers API#

Previously it was not possible to get multiple header values of a response. This is now possible and additional helper functions are available:

🌈 Forced-Colors emulation#

Its now possible to emulate the forced-colors CSS media feature by passing it in the context options or calling Page.emulateMedia().

New APIs#

🎭 Playwright Test#

🤝 test.parallel() run tests in the same file in parallel#

By default, tests in a single file are run in order. If you have many independent tests in a single file, you can now run them in parallel with test.describe.parallel(title, callback).

🛠 Add --debug CLI flag#

By using npx playwright test --debug it will enable the Playwright Inspector for you to debug your tests.

Browser Versions#

  • Chromium 96.0.4641.0
  • Mozilla Firefox 92.0
  • WebKit 15.0

Version 1.14#

🎭 Playwright Library#

⚡️ New "strict" mode#

Selector ambiguity is a common problem in automation testing. "strict" mode ensures that your selector points to a single element and throws otherwise.

Pass strict: true into your action calls to opt in.

// This will throw if you have more than one button!await page.click('button', { strict: true });

📍 New Locators API#

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the Locator and ElementHandle is that the latter points to a particular element, while Locator captures the logic of how to retrieve that element.

Also, locators are "strict" by default!

const locator = page.locator('button');await locator.click();

Learn more in the documentation.

🧩 Experimental React and Vue selector engines#

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to attribute selectors and supports all attribute selector operators.

await page.click('_react=SubmitButton[enabled=true]');await page.click('_vue=submit-button[enabled=true]');

Learn more in the react selectors documentation and the vue selectors documentation.

✨ New nth and visible selector engines#

  • nth selector engine is equivalent to the :nth-match pseudo class, but could be combined with other selector engines.
  • visible selector engine is equivalent to the :visible pseudo class, but could be combined with other selector engines.
// select the first button among all buttonsawait button.click('button >> nth=0');// or if you are using locators, you can use first(), nth() and last()await page.locator('button').first().click();
// click a visible buttonawait button.click('button >> visible=true');

🎭 Playwright Test#

✅ Web-First Assertions#

expect now supports lots of new web-first assertions.

Consider the following example:

await expect(page.locator('.status')).toHaveText('Submitted');

Playwright Test will be re-testing the node with the selector .status until fetched Node has the "Submitted" text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can either pass this timeout or configure it once via the testProject.expect value in test config.

By default, the timeout for assertions is not set, so it'll wait forever, until the whole test times out.

List of all new assertions:

⛓ Serial mode with describe.serial#

Declares a group of tests that should always be run serially. If one of the tests fails, all subsequent tests are skipped. All tests in a group are retried together.

Learn more in the documentation.

🐾 Steps API with test.step#

Split long tests into multiple steps using test.step() API:

Step information is exposed in reporters API.

🌎 Launch web server before running tests#

To launch a server during the tests, use the webServer option in the configuration file. The server will wait for a given port to be available before running the tests, and the port will be passed over to Playwright as a baseURL when creating a context.

⚡️ Introducing Playwright Test#

Playwright Test is a new test runner built from scratch by Playwright team specifically to accommodate end-to-end testing needs:

  • Run tests across all browsers.
  • Execute tests in parallel.
  • Enjoy context isolation and sensible defaults out of the box.
  • Capture videos, screenshots and other artifacts on failure.
  • Integrate your POMs as extensible fixtures.

Installation:

npm i -D @playwright/test

Simple test tests/foo.spec.ts:

Running:

npx playwright test

👉 Read more in Playwright Test documentation.

🧟‍♂️ Introducing Playwright Trace Viewer#

Playwright Trace Viewer is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:

  • page DOM before and after each Playwright action
  • page rendering before and after each Playwright action
  • browser network during script execution

Traces are recorded using the new browserContext.tracing API:

Traces are examined later with the Playwright CLI:

That will open the following GUI:
