Hi, can you specify where are you seeing that skipEnrollmentChecks?

#

GooglePay would be "available" on a device with GooglePay setup. Are you running automated UI on real devices?

#

skipEnrollmentChecks -> by stepping into paymentRequest.canMakePayment

#

Our 'fast' target for automated tests is a Chrome browser with device emulation on

#

Google Pay won't actually be setup, I'd like to bypass that check and mock the PaymentRequest response.

#

Usually I would assume that simply mocking PaymentRequest.prototype.canMakePayment would be sufficient (which we do for other payment gateways, and also for Apple Pay on Stripe with window.ApplePaySession)

Hey sorry for late response. I have been in MTGs

No problem, you don't owe me your time 🙂

#

Yeah I think mocking canMakePayment() could be enough. That method decide whether to mount the button or not.

#

It seems to ignore it, though

#

PaymentRequest.prototype.canMakePayment = () => Promise.resolve(true);

#

I do see that it's doing some messaging, possibly from a service worker?

#

Perhaps it's doing the PaymentRequest check in there instead?

#

After swapping it like that you still see it sent messages?

#

only by displaying the button (not touching it)?

#

I mean that even with that mock in place, calling Stripe's paymentRequest.canMakePayment still returns { googlePay: false }

#

Something like:

PaymentRequest.prototype.canMakePayment = () => Promise.resolve(true);

const stripe = await loadStripe(API_KEY);
const paymentRequest = stripe.paymentRequest({
    country: "AU",
    currency: "AUD",
    total: {
        label: "test",
        amount: 100,
    }
});

const result = await paymentRequest.canMakePayment();

console.log(result.googlePay) // false

#

How about mocking by wrapping that method into a custom method?

#

then swap the wrapper method instead

Thanks. That might work. I was hoping to do it with a lighter hand though
