title: Disable Coverage on Untested Files - Jest
body: <p>When using @vue/cli-plugin-unit-jest, I am receiving coverage reports each time I run my unit tests, regardless of whether I have the <code>--coverage</code> flag in the execution line or not. I do not want to receive coverage reports on all of my untested files. When searching for an answer online, there are numerous questions about how to turn that feature on, not turn it off. I can't find it in the documentation either.</p>
  
  <p>How do you disable the <code>Coverage on Untested Files</code> feature in Jest?</p>
