How can I import Jest?
<p>I would like to get rid of global variables in my Jest test code. Specifically <code>describe</code>, <code>it</code>, and <code>expect</code>:</p>
<pre class="lang-js prettyprint-override"><code>describe('Welcome (Snapshot)', () =&gt; {
  it('Welcome renders hello world', () =&gt; {
    // ...
  });
});
</code></pre>
<p>So I tried to add:</p>
<pre class="lang-js prettyprint-override"><code>import { describe, it } from 'jest';
</code></pre>
<p>and</p>
<pre class="lang-js prettyprint-override"><code>import jest from 'jest';

jest.describe('Welcome (Snapshot)', () =&gt; {
  jest.it('Welcome renders hello world', () =&gt; {
    // ...
  });
});
</code></pre>
<p>And other variation but it's not working.</p>
<p>How can I get my Jest test code working without globals?</p>
