Testing

Testing the Alipay+ integration

Test in the sandbox environment first.

Pre-flight checklist

Check	Where to verify
Page is served over HTTPS	Browser address bar
Component bundle loads from test-pay.dnapayments.com	Network tab
Alipay+ is enabled on your test terminal (confirm with DNA Payments)	DNA Payments account manager
init() receives a valid access_token	Your backend
paymentData contains at least amount, currency and paymentSettings.terminalId	Your code

Scenarios to run

Scenario	How to trigger	Expected event
Successful payment	Tap the button, scan the QR with a sandbox Alipay+-compatible wallet, complete the payment	onPaymentSuccess(result)
User closes the modal	Tap the button, then close the QR modal	onCancel()
QR countdown expires	Tap the button, do nothing until the timer hits zero	onError({ code: 1006 })
paymentData missing	Call init() without paymentData and do not return one from onBeforeProcessPayment	onError({ code: 1004 })
Token missing	Call init() without token and do not return one from onBeforeProcessPayment	onError({ code: 1005 })
onBeforeProcessPayment throws	Throw an exception inside onBeforeProcessPayment	onError({ code: 1007 })
paymentData mismatch	Return paymentData from onBeforeProcessPayment whose amount, currency or delivery address differs from the init() values	onError({ code: 1011 })

See Handling Error Codes for the full code list.

Troubleshooting

• Button does not render. Confirm the container element exists in the DOM at the time of init() and that the script has loaded. onError({ code: 1001 }) fires when the mount fails.
• QR modal closes before the customer scans. Check that paymentTimeoutInSeconds is large enough for your audience. Default is 900 (15 minutes), bump it via init() or from onBeforeProcessPayment if needed.
• 1011 after the customer authorizes. Your onBeforeProcessPayment is returning a paymentData with a different amount, currency or delivery address than the one passed at init(). Use onBeforeProcessPayment to add server-side fields (like invoiceId), not to change the displayed total.
• 401 on every attempt. The access token is expired or has the wrong scopes. Refresh it via your backend, see Authentication.
