title: Jest+vue: "Cannot find module ....vue"
body: <p>I'm really just trying to have a skeleton of a jest+vue for my library and quickly get this error.
  I know the structure is not the usual jest structure, I here try to describe one test with an auxiliary control.</p>
  
  <p>Here is the content of my <code>test</code> folder: <code>arrays.specs.ts</code> and <code>arrays.vue</code></p>
  
  <p>Here is the config:</p>
  
  <pre class="lang-js prettyprint-override"><code>module.exports = {
    moduleFileExtensions: [
      "js",
      "ts",
      "vue"
    ],
    roots: [
      "&lt;rootDir&gt;/test"
    ],
    testEnvironment: "jest-environment-jsdom",
    testMatch: [
      "**/?(*.)+(spec|test).[tj]s?(x)"
    ],
    transform: {
      ".*\\.(vue)$": "vue-jest",
      ".*\\.(ts)$": "ts-jest"
    },
  };
  </code></pre>
  
  <p>I have installed these 3 packages: <code>@vue/test-utils</code>, <code>ts-jest</code> and <code>vue-jest</code></p>
  
  <p>Now, with this, I still end up with this error when running jest:</p>
  
  <pre><code>    test/arrays.spec.ts:4:20 - error TS2307: Cannot find module './arrays.vue'.
  
      import Arrays from './arrays.vue'
  </code></pre>
  
  <p>I really don't see what I am missing.</p>
