# 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

```bash

# with npm

npm install jest-os-detection

# with yarn

yarn add jest-os-detection

```

## Setup

In your package.json

```json

"jest": {

    "setupFilesAfterEnv": ["jest-os-detection"],

  }

```

## Usage

```js

describe.onWindows('this describe is only interpreted on Windows', () => {

  it.onMac('this test is only interpreted on Mac', () => {})

  test.onLinux('this test is only interpreted on Linux', () => {})

  it.onMac.skip('this test is only interpreted on Mac but skipped', () => {})

  test.onLinux.skip('this test is only interpreted on Linux but skipped', () => {})

  it.onMac.only('only this test is executed on Mac', () => {})

  test.onLinux.only('only this test is executed on Linux', () => {})

})

describe.onWindows.each([1, 2, 3])('several describe on windows', describeValue => {

  it.onMac.each([1, 2, 3, 4])('several tests on windows', testValue => {})

  test.onLinux.each([1, 2, 3, 4])('several tests on windows', testValue => {})

  it.onMac.each.skip([1, 2, 3, 4])('several tests skipped on windows', testValue => {})

  test.onLinux.each.skip([1, 2, 3, 4])('several tests skipped on windows', testValue => {})

  it.onMac.each.only([1, 2, 3, 4])('only these tests will be executed on windows', testValue => {})

  test.onLinux.each.only([1, 2, 3, 4])('only these tests will be executed on windows', testValue => {})

})

```
