Quick use cases

Create flat YAML fixtures for application tests. Test YAML parsing and data-import workflows. Prepare readable sample records for development and documentation.

Common generator issues

A consumer expects nested configuration instead of a flat record list. Scalar values are interpreted as an unexpected type. Field names do not match the target schema.

Generator feature notes

  • Each generated record is an item in a YAML list.
  • Configured fields appear as flat key-value pairs.
  • The output is intended for record-based data, not nested application or Kubernetes configuration.

Feature boundaries

Generate up to 5,000 records per file. Use up to 25 fields and 10 files per run. The generator produces a YAML list of flat records.

Sample output structure

- id: 1
  name: John
  email: john@example.com

Dataset generator FAQ

What YAML structure does the generator produce?

It produces a YAML list in which each item is a flat record containing the configured fields.

Can it generate Kubernetes manifests?

No. The generator creates flat record datasets and does not produce the nested schema required by Kubernetes manifests.

Can I control YAML field names and value types?

Yes. Configure the name and data type of each field before generating the dataset.
