title: Code coverage from Jest to stdout to GitLab
body: <p>I am running jest test with code coverage in GitLab CI and GitLab captures the percentage from stdout of a runner in gitlab.</p>
  
  <p><code>jest --coverage</code> produces the coverage in stdout and gitlab captures it using <code>/All files[^|]*\|[^|]*\s+([\d\.]+)/</code> regexp but when I run 
  <code>jest --coverage --json --outputFile=xyz.json</code> sadly jest doesn't print the code coverage to stdout.</p>
  
  <p>What can I do to get code coverage in stdout from jest when <code>--json</code> arguments is given to jest?</p>
  
  <p><code>jest version : v22.4.3</code> same for jest-cli</p>
