Playwright v1.21 updates

Highlights

• New experimental role selectors that allow selecting elements by their ARIA role, ARIA attributes and accessible name.

  // Click a button with accessible name "log in"
  await page.click('role=button[name="log in"]')

  To use role selectors, make sure to pass PLAYWRIGHT_EXPERIMENTAL_FEATURES=1 environment variable:

  // playwright.config.js
  process.env.PLAYWRIGHT_EXPERIMENTAL_FEATURES = '1';
  module.exports = {
    /* ... */
  };

• New scale option in Page.screenshot for smaller sized screenshots.

• New caret option in Page.screenshot to control text caret. Defaults to "hide".

• New method expect.poll to wait for an arbitrary condition:

  // Poll the method until it returns an expected result.
  await expect.poll(async () => {
    const response = await page.request.get('https://api.example.com');
    return response.status();
  }).toBe(200);

  expect.poll supports most synchronous matchers, like .toBe(), .toContain(), etc.
