title: Is there a way to generate Jest / Istanbul coverage report in junit.xml format
body: <p>I'd like to use Gitlab CI for tracking / embedding the coverage analysis in merge requests. The <a href="https://docs.gitlab.com/ee/ci/yaml/README.html#artifactsreports" rel="noreferrer"><code>gitlab-ci.yml artifacts:reports:junit</code></a> config option seems to be suitable for this task. However, this requires the <strong>coverage</strong> 
   output to be in junit.xml format.</p>
  
  <p>I don't find a proper setup for outputting the coverage  this format. Neither can I find a tool to convert from lcov/json/clover to junit.xml .</p>
