How to test Google & Apple Pay
For Google Pay, only Chrome browser is supported, and a valid Google Credit card, you can add 4242424242424242 as test card.
For Apple Pay, Stripe test card information can’t be saved to Wallet in iOS. Instead, Stripe recognizes when you’re using your test API keys and returns a successful test card token for you to use. This allows you to make test payments using a live card without it being charged.
