iFrames with frameLocator

// Locate elements directly inside an iframe:
const paymentFrame = page.frameLocator("#stripe-frame");
await paymentFrame.getByLabel("Card Number").fill("4242 4242 4242 4242");
// Multi-tabs:
const newPagePromise = context.waitForEvent("page");
await page.getByRole("link", { name: "Help Center" }).click();
const newPage = await newPagePromise;
await expect(newPage).toHaveTitle(/Help/);
