  <p>I was using <code>ava</code> to run tests. But these logs are annoying me. I tried to set webpack <code>stats</code> config in <code>nuxt.config.js</code>, but it is not working. Can someone provide any help?</p>
  
  <pre><code>// Does not work
  {
    ...
    build: {
      ...
      extend (config, { isClient }) {
        ...
        if (process.env.NODE_ENV === 'test') {
          config.stats = 'errors-only'
        }
      }
    }
   ...
  }
  </code></pre>
  
  <hr>
  
  <p><strong>Update:</strong> The following can hide assets logs, but it still shows warnings:</p>
  
  <pre><code>// Works, but does not hide warnings
  {
    ...
    build: {
      stats: process.env.NODE_ENV === 'test' ? 'errors-only' {
        chunks: false,
        children: false,
        modules: false,
        colors: true,
        assets: true,
        warnings: true,
        errors: true,
        excludeAssets: [
          /.map$/,
          /index\..+\.html$/,
          /vue-ssr-client-manifest.json/
        ]
      },
      ...
    }
   ...
  }
  </code></pre>
  
  <p>But this does not hide the warnings:</p>
