# Mimlet

> Typed fixtures. Coherent scenarios. Failures you can replay. A modular schema-aware test-data toolkit with a dependency-free core.

Published alpha: 0.1.0-alpha.2, available on npm’s next channel. Install @mimlet/core and only the adapters you need; see Getting started for matching versions. Generation is capability-specific; arbitrary validators may require a factory.
