Step-by-Step Guide

Follow this implementation to set up the pattern in your test suite.

1. Core Implementation

test('Stripe payment completes successfully', async ({ page }) => {
  await page.goto('/checkout');
  const stripeFrame = page.frameLocator('[name*="privateStripeFrame"]');
  await stripeFrame.getByPlaceholder('Card number').fill('4242 4242 4242 4242');
  await stripeFrame.getByPlaceholder('MM / YY').fill('12 / 26');
  await stripeFrame.getByPlaceholder('CVC').fill('314');
  await page.getByRole('button', { name: 'Pay $99.00' }).click();
  await expect(page.getByText('Payment successful')).toBeVisible();
});
