jest-jspm

A Helper to generate Jest configuration for a JSPM/SystemJS based application. Since System JS applies its own logic for how to resolve dependencies Jest cannot locate them while running. This library helps you test your app with Jest by generating the correct mappings configuration Jest understands.
