[Vuejs]-Unit Test with external template file in Vue

I solve it adding more loaders 😀

module: {
  rules: [
    {
      test: /\.pug/,
      use: [
        'html-loader',
        'pug-loader?sourceMap'
      ]
    },
    {
      test: /\.css$/,
      use: [
        'style-loader',
        {
          loader: 'css-loader',
          options: {
            importLoaders: 1
          }
        },
        'postcss-loader'
      ]
    }
}
