Highlights

• New options for methods page.screenshot(), locator.screenshot() and elementHandle.screenshot():

  • Option animations: "disabled" rewinds all CSS animations and transitions to a consistent state.
  • Option mask: Locator[] masks given elements, overlaying them with pink #FF00FF boxes.

• expect().toMatchSnapshot() now supports anonymous snapshots: when snapshot name is missing, Playwright Test will generate one automatically:

  expect('Web is Awesome <3').toMatchSnapshot();

• New maxDiffPixels and maxDiffPixelRatio options for fine-grained screenshot comparison using expect().toMatchSnapshot():

  expect(await page.screenshot()).toMatchSnapshot({ maxDiffPixels: 27, // allow no more than 27 different pixels. });

  It is most convenient to specify maxDiffPixels or maxDiffPixelRatio once in TestConfig.expect.

• Playwright Test now adds TestConfig.fullyParallel mode. By default, Playwright Test parallelizes between files. In fully parallel mode, tests inside a single file are also run in parallel. You can also use --fully-parallel command line flag.

  // playwright.config.ts export default { fullyParallel: true, };

• TestProject.grep and TestProject.grepInvert are now configurable per project. For example, you can now configure smoke tests project using grep:

  // playwright.config.ts export default { projects: [ { name: 'smoke tests', grep: /@smoke/, }, ], };

• Trace Viewer now shows API testing requests.

• locator.highlight() visually reveals element(s) for easier debugging.
