# Evaluate your purchase and decline checklist

Turn your manual checkout checklist into browser tests. Evaluate the actual success and decline outcomes in test mode, locally or hosted.

Turn your manual checkout checklist into browser tests. Evaluate the actual success and decline outcomes in test mode, locally or hosted.

## Who it is for

- Role: Developer responsible for checkout
- Company: Web products with a purchase flow
- Trigger: A cart, pricing or checkout change needs release testing

## Why this is underserved

- Cart contents and totals can be wrong even when the page loads.
- Payment-provider behavior needs its own sandbox and integration tests.
- A browser result only supports the outcome that the test actually verifies.

## The workflow

Before: A developer manually buys the paid plan with a test card, checks the app confirmation, then checks that a declined card grants no paid access.

After: Onboarding drafts those browser steps and inspects the real result. Save working tests and rerun them after a release; complete payment compatibility must be established for the chosen runner.

## How Zerocheck handles it

1. Prepare test products, a test customer and sandbox payment settings.
2. Describe the purchase and decline outcomes in Add a test or Import checklist, or use repository YAML locally.
3. Review the drafted actions and final assertion before relying on the result.
4. Run against staging, inspect failures and screenshots, then rerun the saved test after an app change.

## Good fit when

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

## Frequently asked questions

### Is Stripe checkout compatibility already established?

No. It does not provide payment, 3DS or webhook helpers. Confirm browser compatibility during the evaluation and keep unsupported provider flows in a separate test harness.

### Can a test spend money?

Payment actions are allowed. Use a sandbox and test cards; do not treat a browser test as read-only.
