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.
Install
npm install jest-os-detection
yarn add jest-os-detection
Setup
In your package.json
"jest": {
"setupFilesAfterEnv": ["jest-os-detection"],
}
