Not getting coverage output

[tinkertrain]

Hello!

I looked for an answer for this and tried multiple things... but I can't get code coverage working, maybe someone can shed a light into what this isn't working:

This is the karma conf file:

/* eslint-disable no-var */
var path = require('path');

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', 'sinon'],
    files: [
      './test/**/*.js'
    ],
    preprocessors: {
      './test/**/*.js': ['webpack']
    },
    webpack: {
      module: {
        loaders: [
          {
            test: /\.js?$/,
            loaders: ['babel-loader'],
            exclude: /node_modules/
          }
        ],
        postLoaders: [
          {
            test: /\.js$/,
            loaders: ['istanbul-instrumenter'],
            exclude: /(test|node_modules)\//
          }
        ]
      },
      resolve: {
        root: [
          path.join(__dirname, 'src'),
          'node_modules'
        ]
      }
    },
    webpackMiddleware: {
      noInfo: true
    },
    plugins: [
      require('karma-webpack'),
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-phantomjs-launcher'),
      require('karma-coverage'),
      require('karma-sinon'),
      'karma-nyan-reporter',
      'istanbul-instrumenter-loader'
    ],
    reporters: ['nyan', 'coverage'],
    nyanReporter: {
      suppressErrorReport: false
    },
    coverageReporter: {
      type: 'html',
      dir: 'coverage/'
    },
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['PhantomJS'],
    singleRun: false
  });
};

When I run karma I don't errors and the tests are being run, but I don't get a folder 'coverage' nor html files created... did I missed something obvious? (this is the first time I'm trying Istanbul code coverage btw)

Thanks!
