Install

Installation is simple. First, run one of the following two commands, depending on whether you’re using Yarn or npm:

Yarn

yarn add --dev rugged

npm

npm install --save-dev rugged

Then, add rugged to the package.json file’s test script:

package.json

{
    "scripts": {
        "test": "rugged"
    }
}

If you already have a test script, add && rugged to the end of it:

package.json

{
    "scripts": {
        "test": "... && rugged"
    }
}
