Clock

Utilizing the new Clock API allows to manipulate and control time within tests to verify time-related behavior. This API covers many common scenarios, including:

• testing with predefined time;
• keeping consistent time and timers;
• monitoring inactivity;
• ticking through time manually.

// Initialize clock and let the page load naturally.
await page.clock.install({ time: new Date('2024-02-02T08:00:00') });
await page.goto('http://localhost:3333');
// Pretend that the user closed the laptop lid and opened it again at 10am,
// Pause the time once reached that point.
await page.clock.pauseAt(new Date('2024-02-02T10:00:00'));
// Assert the page state.
await expect(page.getByTestId('current-time')).toHaveText('2/2/2024, 10:00:00 AM');
// Close the laptop lid again and open it at 10:30am.
await page.clock.fastForward('30:00');
await expect(page.getByTestId('current-time')).toHaveText('2/2/2024, 10:30:00 AM');

See the clock guide for more details.

Test runner

• New CLI option --fail-on-flaky-tests that sets exit code to 1 upon any flaky tests. Note that by default, the test runner exits with code 0 when all failed tests recovered upon a retry. With this option, the test run will fail in such case.

• New enviroment variable PLAYWRIGHT_FORCE_TTY controls whether built-in list, line and dot reporters assume a live terminal. For example, this could be useful to disable tty behavior when your CI environment does not handle ANSI control sequences well. Alternatively, you can enable tty behavior even when to live terminal is present, if you plan to post-process the output and handle control sequences.

  # Avoid TTY features that output ANSI control sequences
  PLAYWRIGHT_FORCE_TTY=0 npx playwright test
  Enable TTY features, assuming a terminal width 80
  PLAYWRIGHT_FORCE_TTY=80 npx playwright test

• New options testConfig.respectGitIgnore and testProject.respectGitIgnore control whether files matching .gitignore patterns are excluded when searching for tests.

• New property timeout is now available for custom expect matchers. This property takes into account playwright.config.ts and expect.configure().

  import { expect as baseExpect } from '@playwright/test';
  export const expect = baseExpect.extend({
  async toHaveAmount(locator: Locator, expected: number, options?: { timeout?: number }) {
  // When no timeout option is specified, use the config timeout.
  const timeout = options?.timeout ?? this.timeout;
