title: Jest ignore Cypress test
body: <p>I have a <code>create-react-app</code> app and used to use <code>jest</code> for testing but I'm slowly migrating to <code>cypress</code>.</p>
  <p>The thing is, now when I run my <code>jest</code> tests, it includes my <code>cypress</code> tests and gives an error</p>
  <pre><code>ReferenceError: Cypress is not defined
  </code></pre>
  <p>How can I make it that my <code>jest</code> (naming convention <code>*.test.js</code>) test ignore my <code>cypress</code> test (which are usually called <code>*.spec.js</code>)?</p>
