Jest OS detection

This module allows you to specify on which OS your tests should run. A common use case would be to have a CI running on different OS (say mac and windows) but you want to have all your tests in the same file. Unfortunately, some of your tests should only run on a specific platform due to OS specific features.

All tests that should not be run on the current platform will be automatically skipped.

Install

# with npm 
npm install jest-os-detection
 
# with yarn 
yarn add jest-os-detection

In your package.json
