title: Disabling the 'Your test suite must contain at least one test' rule in Jest
body: <p>Jest has a <em>'Your test suite must contain at least one test.'</em> rule. It complains that if I have a file that isn't a test suite it cannot exist in the <code>__test__/</code> directory that I have created (see below). This basically means everything in that folder (including the subfolders) must be a test suite.</p>
  
  <p>How do I get around this? I really want to store my mock data objects with my test suites. </p>
