title: Jest - No output of test results
body: <p>I've been having difficulties with Jest ever since I tried to begin using it. No tests I try to run and with what options I try to pass Jest, I never get the 'Pass' / 'Fail' output results in the console. </p>
  
  <p>Jest always just outputs 'Done'</p>
  
  <p>Using the 'Nuxt CLI' there is a default test written as:</p>
  
  <pre><code>import { mount } from '@vue/test-utils'
  import Logo from '@/components/Logo.vue'
  
  describe('Logo', () =&gt; {
    test('is a Vue instance', () =&gt; {
      const wrapper = mount(Logo)
      expect(wrapper.isVueInstance()).toBeTruthy()
    })
  })
  
  </code></pre>
  
  <p>So far I have tried:</p>
  
  <pre><code>yarn test
  yarn test --verbose
  yarn test --watch
  yarn test --watchAll
  yarn test --no-watchmen
  </code></pre>
  
  <p>Every single time, the result is as follows:</p>
  
  <pre><code>yarn run v1.21.1
  $ jest
  Done in 0.72s.
  </code></pre>
  
  <p>Current <strong>jest.config.js</strong>:</p>
  
  <pre><code>module.exports = {
    moduleNameMapper: {
      '^@/(.*)$': '&lt;rootDir&gt;/$1',
      '^~/(.*)$': '&lt;rootDir&gt;/$1',
      '^vue$': 'vue/dist/vue.common.js'
    },
    moduleFileExtensions: ['js', 'vue', 'json'],
    transform: {
      '^.+\\.js$': 'babel-jest',
      '.*\\.(vue)$': 'vue-jest'
    },
    collectCoverage: true,
    collectCoverageFrom: [
      '&lt;rootDir&gt;/components/**/*.vue',
      '&lt;rootDir&gt;/pages/**/*.vue'
    ]
  }
  
  </code></pre>
  
  <p>This seems to be the default config for Nuxt.</p>
  
  <p>Any help would be appreciated</p>
