Smart Autofill dev qa

Smart Autofill fills forms with plausible test data, so QA engineers stop typing "aaa / bbb / test@test.com" into the same checkout twenty times a day.

What it does

• Realistic identities — first names match the selected gender and the age group detected from the form. A passenger block labelled "Child 1" gets a first name actually given to children today, not to their grandparents.
• 41 countries — pick a profile country and names, addresses, phone numbers and postal-code formats follow: Turkish, Japanese, Brazilian, Indian, Saudi, German, British and more.
• Multi-passenger forms — each block gets its own consistent identity instead of the same name repeated.
• Stripe test cards — a searchable catalogue of the documented test numbers: success, declines, 3-D Secure, disputes, fraud, verification failures, and per-country cards.

• It never checks a checkbox. Ticking an option would silently change the scenario you are testing, so consent boxes are left for you.
• It only fills when you ask, by clicking the toolbar button or the popup. Nothing happens on page load.
• It collects nothing, sends nothing, and makes no network request of any kind.

• The card numbers are Stripe's publicly documented TEST numbers (https://docs.stripe.com/testing). They only work against Stripe test API keys and are rejected in production. They cannot be used to pay for anything.
