==== This checks your integration logic end-to-end: ====
# Follow Google Pay web/API docs: use environment: "TEST" in the payment request. - docs: https://developers.google.com/pay/api/web/guides/resources/test-card-suite
# Use the Google Pay test card numbers listed in Google’s docs (these produce a token that the payment gateway recognizes in test mode).
# For gateway tokenization with Stripe in test mode: - Use Stripe’s test publishable key on the client and secret key server-side. - Configure tokenizationSpecification for gateway: "stripe" and the stripe parameters (see docs).
# Example: test PaymentDataRequest JSON (web) – set environment: "TEST", use allowedPaymentMethods CARD and TOKENIZATION_SPECIFICATION for your gateway. Send resulting token to your backend (in test mode) and attempt a charge using the gateway’s test API (Stripe test secret key).
# To test Android, run on an emulator that has Google Play services and use the Google Pay test transport.

This validates button flow, payment token creation, and your backend’s ability to decode/test-charge the token.

Important: Using Google Pay TEST mode will not insert a persistent payment card into your Wallet UI for real production checkouts.
