Help ! Dont work in my case.

Hi !

I have the following structure :

├── app/
│   └──  scripts/
│       ├── modules/
│       │      └── foo/
│       │         └── index.js
│       └── app.js
└── test/
    ├── spec/
    │  └── modules/
    │       └── foo/
    │           └── index.js
    └── karma.conf.js

And my config looks like this :

module.exports = function (config) {
  config.set({
    // basePath, frameworks ....
    plugins: [
      'karma-phantomjs-launcher',
      'karma-jasmine',
      'karma-coverage',
      'karma-tap-reporter'
    ],
    files: [
      // Dependencies
      'test/spec/*.js',
      'test/spec/modules/**/*.js',
    ],
    preprocessors: {
      'app/scripts/app.js': ['webpack', 'sourcemap', 'coverage'],
      'app/scripts/modules/**/*': ['coverage'],
      'test/spec/*.js': ['babel'],
      'test/spec/modules/**/*.js': ['babel']
    },
    plugins: [
      'karma-phantomjs-launcher',
      'karma-jasmine',
      'karma-coverage',
      'karma-sinon-chai',
      'karma-tap-reporter',
      'karma-babel-preprocessor',
      'karma-coffee-preprocessor',
      'karma-sourcemap-loader',
      require("karma-webpack")
    ],
    webpack: {
      module: {
        postLoaders: [
          { test: /\.js$/, loader: 'istanbul-instrumenter' }
        ],

        loaders: [
          // JS
          { test: /\.js?$/, exclude: /node_modules/, loader: 'babel-loader' }
        ]
      }
    },
    // Coverage reporters, babel preprocessor ...
  });
}

I tried to put istanbul-instrumenter as preLoader and postLoader but it never works for me.

In preLoader, my tests fail, and in postLoader, I have the following error.

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

Any idea ?

PS : My coverage worked good before webpack migration and all of my tests pass without preLoader istanbul instrumenter.

Thanks

could you please try setup described in readme? it's difficult to understand what is wrong without example repo.
