title: How to disable ts-loader (tslint) checking in vue-cli 3 project?
body: <p>When I run <code>yarn test:unit</code> the process runs and then after a few seconds it shows <code>Type checking in progress...</code> and a long list of errors follows. </p>
  
  <p>I tried following the advice to remove <a href="https://stackoverflow.com/questions/49121110/how-to-disable-eslint-on-vue-cli-3">eslint</a> but it didn't work.</p>
  
  <p>Here is my tsconfig.json (I don't have a tslint.json)</p>
  
  <pre><code>{
