New APIs

• Test tags

  New tag syntax for adding tags to the tests (@-tokens in the test title are still supported).

  test('test customer login', { tag: ['@fast', '@login'] }, async ({ page }) => {
    // ...
  });

  Use --grep command line option to run only tests with certain tags.

  npx playwright test --grep @fast

• Annotating skipped tests

  New annotation syntax for test annotations allows annotating the tests that do not run.

  test('test full report', {
    annotation: [
      { type: 'issue', description: 'https://github.com/microsoft/playwright/issues/23180' },
      { type: 'docs', description: 'https://playwright.dev/docs/test-annotations#tag-tests' },
    ],
  }, async ({ page }) => {
    // ...
  });

• page.addLocatorHandler()

  New method page.addLocatorHandler() registers a callback that will be invoked when specified element becomes visible and may block Playwright actions. The callback can get rid of the overlay. Here is an example that closes a cookie dialog when it appears.

  // Setup the handler.
  await page.addLocatorHandler(
      page.getByRole('heading', { name: 'Hej! You are in control of your cookies.' }),
      async () => {
        await page.getByRole('button', { name: 'Accept all' }).click();
      });
  // Write the test as usual.
  await page.goto('https://www.ikea.com/');
  await page.getByRole('link', { name: 'Collection of blue and white' }).click();
  await expect(page.getByRole('heading', { name: 'Light and easy' })).toBeVisible();

• Project wildcard filter
  Playwright command line flag now supports '*' wildcard when filtering by project.

  npx playwright test --project='*mobile*'

• Other APIs

  • expect(callback).toPass({ timeout })
    The timeout can now be configured by expect.toPass.timeout option globally or in project config

  • electronApplication.on('console')
    electronApplication.on('console') event is emitted when Electron main process calls console API methods.

    electronApp.on('console', async msg => {
      const values = [];
      for (const arg of msg.args())
        values.push(await arg.jsonValue());
      console.log(...values);
    });
    await electronApp.evaluate(() => console.log('hello', 5, { foo: 'bar' }));

  • page.pdf() accepts two new options tagged and outline.

Breaking changes

Mixing the test instances in the same suite is no longer supported. Allowing it was an oversight as it makes reasoning about the semantics unnecessarily hard.

const test = baseTest.extend({ item: async ({}, use) => {} });
baseTest.describe('Admin user', () => {
  test('1', async ({ page, item }) => {});
  test('2', async ({ page, item }) => {});
});
