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.
