title: How to get the code coverage report using Jest?
body: <p>Is there a way to have code coverage in the JavaScript Jest testing framework, which is built on top of Jasmine?</p>
  <p>The internal framework <a href="https://github.com/facebook/jest/blob/db003d5dc76b966199f8072343de1f18231d82e3/src/defaultTestResultHandler.js#L99-L103" rel="noreferrer">does not</a> print out the code coverage it gets. I've also tried using <a href="https://github.com/gotwarlost/istanbul" rel="noreferrer">Istanbul</a>, <a href="https://github.com/alex-seville/blanket" rel="noreferrer">blanket</a>, and <a href="https://github.com/tntim96/JSCover" rel="noreferrer">JSCover</a>, but none of them work.</p>
