# 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 validated sandbox workflow.

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

## Who it is for

- Role: Engineer responsible for transactional flows
- Company: Web products with carts or billing interfaces
- Trigger: A release changes pricing, forms or account pages

## Why this is underserved

- A working backend does not prove a customer can complete the browser flow.
- Test data must make prices, currencies and account state predictable.
- Financial side effects require deliberate sandbox setup.

## The workflow

Before: A release changes the order summary, but the team tests only whether the checkout page opens.

After: The browser test checks the intended item, quantity and visible summary. Separate integration tests verify settlement, webhooks and provider-specific behavior.

## How Zerocheck handles it

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

## Good fit when

- A web app and a repeatable user flow
- A test environment, test accounts and an explicit expected outcome

## Frequently asked questions

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

No. It verifies supported browser outcomes. Payment processing, settlement and compliance require 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.
