About Test credit cards

The Test credit card extension makes it easy to test checkout forms that use either Stripe or Braintree as their payment processor. No more manually entering test credit card numbers or struggling to find the right test card to use. With a single click, the Test Credit Card Generator will provide you with a valid test credit card number that you can use in your checkout form. That extension will try to autofill your checkout form or copy the number in your clipboard if we are not able to do the auto-fill.
