db-mockdata 0.4.3

Simple package for creating mockdata for a live database, according to specified relational schema.

Mock data generation

This is small project for generating artificial / mock data, conforming to the specified DB schema. It can be useful to either generate pseudo-realistic data in the database, or prepare large amounts of mock data for stress testing.

The package allows for generating mock data for specified database schema.

Simple configuration file schema:
