pm-dummy-dataset

Generate realistic TypeScript mock data and SQL seed files by analyzing your spec.md to produce believable test datasets. The tool reads entity definitions and constraints, then outputs TypeScript mocks and SQL seeds for database provisioning and local development environments.

Test data generation includes normal records (10-20 rows), boundary value records (2-3 rows), an empty dataset (1 record), and error-inducing records (2-3 rows). This variety ensures comprehensive coverage for automated testing and validates foreign key integrity with UUIDv4 IDs.

Yes, the mock data generator enforces UUIDv4 IDs and maintains foreign key integrity across all generated records. It strictly uses only the enum values and constraints defined in your spec.md, ensuring referential consistency for local development databases.

You can use the generated SQL seeds for automated testing, local development environments, and foundation-stage DB provisioning. The generated data applies realistic constraints and enum values from spec.md to ensure believable seed data across all testing scenarios.

The best way to generate edge case and error-inducing seed data is using a spec.md generator that automatically includes boundary values and error-triggering records. It creates 2-3 edge case rows and 2-3 error rows alongside normal data to test validation logic.

No specific database platform is required since the tool generates standard SQL seed files from spec.md definitions. The output works for foundation-stage DB provisioning across any SQL-compatible database used in local development or automated testing environments.
