Testing / Playwright Interview questions

How does Playwright handle multiple tabs and windows?

Each new tab or window opened from the page - via a link with target="_blank" or a window.open() call - fires a 'page' event on its parent BrowserContext. Playwright doesn't switch focus automatically like some tools; instead, you capture the new page object explicitly.

const [newPage] = await Promise.all([
  context.waitForEvent('page'),
  page.getByRole('link', { name: 'Open in new tab' }).click(),
]);
await newPage.waitForLoadState();

From there, newPage is an independent Page object with its own locators and lifecycle, while still sharing the same cookies and storage as the original page because they belong to the same browser context. This makes it easy to assert on both tabs, or close one while keeping the other active.

Take quiz

A new tab opened via target=_blank triggers which event on the BrowserContext? 'newpage' automatically switches focus

✗ Try again if not.

A 'page' event that must be captured explicitly

✓ Correct! Well done.

No event at all

✗ Try again if not.

A new tab opened this way shares which of the following with the original page? Nothing - it's fully isolated

✗ Try again if not.

Cookies and storage, since they share a browser context

✓ Correct! Well done.

Only the screenshot history

✗ Try again if not.
