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

      "Version: v1.62.0",
      "signal: An `AbortSignal` that cancels the operation; for locator assertions, aborting fails the assertion like a timeout.",

      "Prerequisite: The `signal` option was added in Playwright v1.62.",

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