title: jest ignore all node_modules except 1 package
body: <p>I'm using jest for doing testing and currently I can ignore node_modules. The issue, however, is that theres 1 package in node_modules that I want to get transpiled with babel. Right now my ignored patterns look like this:</p>
  
  <pre><code>testPathIgnorePatterns: ['./node_modules/'],
  </code></pre>
  
  <p>if my package is called 'my-package', how can I make it so testPathIgnorePatterns doesn't ignore that inside node_modules? </p>
