title: Jest / ESLint fail is not defined
body: <p>I've just generated a fresh project with <code>npx react-native init</code> and ESLint is complaining in one of my test files:</p>
  <pre><code>   9:1   error  'describe' is not defined    no-undef
    12:5   error  'beforeEach' is not defined  no-undef
    16:5   error  'afterEach' is not defined   no-undef
    20:5   error  'test' is not defined        no-undef
    28:17  error  'fail' is not defined        no-undef
    30:13  error  'expect' is not defined      no-undef
  </code></pre>
  <p>Based on the <a href="https://eslint.org/docs/user-guide/configuring#specifying-environments" rel="nofollow noreferrer">docs</a> and this <a href="https://stackoverflow.com/questions/31629389/how-to-use-eslint-with-jest">thread</a>, I've added:</p>
  <pre><code>env: {
      jest: true,
  },
  </code></pre>
  <p>to my <code>.eslintrc.js</code> file. However, ESLint is still complaining with:</p>
  <pre><code>  28:17  error  'fail' is not defined  no-undef
  </code></pre>
  <p>Has anyone already experienced and solved this issue ?</p>
  <p>Here are the jest dependencies versions in <code>package.json</code>:</p>
  <pre><code>&quot;babel-jest&quot;: &quot;^26.5.2&quot;,
  &quot;jest&quot;: &quot;^26.5.3&quot;,
  </code></pre>
