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

Scheduling and billing code fails around DST switches, leap days and inverted periods.

What is requested

300 temporal-sequence and 100 boundary records.

Policy gates

Within the profile.

What is provisioned

A certified synthetic dataset.

Expected output

AUTO_APPROVED.

Cleanup

afterAll releases.

Files

• request.yaml
• dates.test.ts

Run

1. A tenant administrator defines and a second person approves the profile (datanivra test-data define ../../profiles/edge-cases-core.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.
