# Test environment

In the test environment you can force a payment's risk score, which lets you validate the behavior of your integration and rules without relying on the real analysis.

## Simulating a score

For the simulation to apply, the request must meet three conditions:

1. The account must be in the test environment.
2. The `user_id` field must start with the `test_` prefix (for example, `test_123`).
3. The `amount` field must be present.

When these conditions are met, the risk score becomes equal to the cents of the value provided in `amount`, ignoring the automatic analysis. The whole units are disregarded — only the two decimal places matter:

| `amount` | Risk score | Recommendation          |
|----------|------------|-------------------------|
| `100.50` | 50         | Allow (`allow`)         |
| `100.85` | 85         | Challenge (`challenge`) |
| `100.95` | 95         | Deny (`deny`)           |

The ranges that define each recommendation are the ones configured under **Settings > Analysis** — see [Analysis](/en/transactional/analysis/) for the default limits.

> This feature works only in the test environment. In production, the score is always calculated by the platform's analysis.
