About this example

All data is synthetic. DataNivra provisions approved test data into a customer-controlled target; it does not run these tests. Credentials for the target are never returned by DataNivra — your runner holds its own.

Why test data matters

Reconciliation jobs must flag breaks and still produce deterministic totals.

What is requested

500 everyday and 100 reconciliation-break records.

Policy gates

Within the profile.

What is provisioned

A certified synthetic dataset.

Expected output

AUTO_APPROVED.

Cleanup

Fixture releases.

Files

  • request.yaml
  • example.py
  • test_with_datanivra.py

Run

  1. A tenant administrator defines and a second person approves the profile (datanivra test-data define ../../profiles/banking-regression.yaml --submit, then datanivra policies approve).
  2. datanivra test-data validate request.yaml && datanivra test-data plan request.yaml
  3. Run the example with DATANIVRA_BASE_URL and a session or workload token.

Files

Exactly as they are in the examples repository. Every value is a synthetic placeholder; nothing here is a credential.
