title: 'test' is not defined. (no-undef)
body: <p>I'm using eslint(JavaScript Standard Style) with jest</p>
  
  <p>lint keeps me warning about jest's functions are not defined.</p>
  
  <p>I tried </p>
  
  <pre><code>/* eslint-env jest */
  </code></pre>
  
  <p>It works but, I don't want to use it in every test.js file. so I tried.</p>
  
  <p>.eslintrc (in root directory)</p>
  
  <pre><code>{
      "env": {
          "jest": true
        }
  }
  </code></pre>
