v1.62.0

🧱 New component testing model

Component testing moves to a stories and galleries model. A story wraps your component in one specific scenario — hard-coded props, mock data, providers — and a gallery page that you serve renders stories on demand. The new fixtures.mount() fixture navigates to the gallery, mounts a story by id, and returns a Locator scoped to the story's root element:

test('click should expand', async ({ mount }) => {
  const component = await mount('components/Expandable/Stateful');
  await component.getByRole('button').click();
  await expect(component.getByTestId('expanded')).toHaveValue('true');
});

Pass a story type as a template argument to type-check its props, and use update(props) / unmount() on the returned locator to re-render or tear down within a test.

🛑 Cancel operations with AbortSignal

Most operations and web-first assertions now accept a signal option that takes an AbortSignal, letting you cancel long-running actions, navigations, waits, and assertions:

const controller = new AbortController();
setTimeout(() => controller.abort(), 1000);
await page.getByRole('button', { name: 'Submit' }).click({ signal: controller.signal });
await expect(page.getByText('Done')).toBeVisible({ signal: controller.signal });

Providing a signal does not disable the default timeout; pass timeout: 0 to disable it.

🖼️ WebP screenshots

expect(page).toHaveScreenshot() and expect(locator).toHaveScreenshot() can now store snapshots in the WebP format — just give the snapshot a .webp name:

// Visual comparisons store the golden snapshot as lossless WebP.
await expect(page).toHaveScreenshot('homepage.webp');
// Standalone screenshots can trade quality for size with lossy WebP.
await page.screenshot({ path: 'homepage.webp', quality: 50 });

page.screenshot() and [locator.screenshot() (https://playwright.dev/docs/api/class-locator#locator-screenshot) also accept webp as a type, where quality 100 (the default) is lossless and lower values use lossy compression.

🧩 Custom test filtering with Reporter.preprocess()

New reporter.preprocess() hook runs after the configuration is resolved and before reporter.onBegin(), letting a reporter mark individual tests as skipped, excluded, fixed, or failing through a TestRun object:
