# Catch browser regressions around a purchase

Repeat the customer-facing steps around products, carts and account pages with test data. Keep payment processing and provider-specific checks in a sandbox workflow.

A release changes the order summary, but the team only checks whether the checkout page opens. A working backend doesn't show that a customer can complete the browser flow.

A browser test can check the intended item, quantity and visible summary. Separate integration tests cover settlement, webhooks and provider-specific behavior. Test data has to make prices, currencies and account state predictable, and anything with financial side effects needs a deliberate sandbox.

## How to do it in Zerocheck

1. Prepare sandbox products and test accounts.
2. Describe the visible result for one narrow flow.
3. Review the drafted actions, especially any final purchase action.
4. Check screenshots and results before release.

## Frequently asked questions

### Does Zerocheck validate settlement or payment-provider compliance?

No. It checks browser outcomes. Payment processing, settlement and compliance need separate systems and tests.

### Are live payment actions blocked?

No. Payments are allowed, so use test cards and a sandbox. Avoid live customer accounts and real financial transactions.
