Exclude import files like angular.js, angular-ui-router.js, angular-mocks.js etc from Karma coverage reports

Question

My coverage report includes the imports like :

 node_modules\angular-mocks\             |    26.09 |    11.58 |     19.7 |    27.23 |                |

  angular.js                             |    17.56 |     5.43 |     13.7 |    17.88 |... 30418,30423 |

  module.js

My Karma Config is :

// jshint ignore: start
// jscs:disable

// Global karma config
'use strict';


// START_CONFIT_GENERATED_CONTENT
// We want to re-use the loaders from the dev.webpack.config
var webpackConfig = require('./../webpack/webpack.test.config.js');
var preprocessorList = ['webpack', 'sourcemap'];

var karmaConfig = {  
  plugins: [
    'karma-phantomjs-launcher',
    'karma-jasmine',
    'karma-junit-reporter',
    'karma-coverage',
    'karma-chrome-launcher',
    'karma-webpack',
    'karma-sourcemap-loader',

    'node_modules/phantomjs-polyfill/bind-polyfill.js',
    'config/testUnit/test.files.js'
  ],    
  preprocessors: {        
    'config/testUnit/test.files.js': preprocessorList,
    'src/**/!*spec.js': ['coverage'],
     'src/app/**/*.js': ['coverage'],
  },   
  reporters: ['progress', 'junit', 'coverage', 'threshold','html'],    
  coverageReporter: {
    dir: 'reports/coverage',
    includeAllSources:false,
    reporters: [
      { type: 'cobertura', subdir: 'cobertura' },
      { type: 'lcovonly', subdir: 'lcov' },
      { type: 'html', subdir: 'html' },
      { type: 'json', subdir: 'json' },
      { type: 'text' }
    ]
  },    
  junitReporter: {
    outputDir: 'reports/unit/',
    outputFile: 'test-results.xml'
  },
  htmlReporter: {
    outputFile: 'reports/unit/Test-Results.html'
  },     
  webpack: {
    // Load the source code using test.files.js
    entry: {},    
    module: {
      preLoaders: webpackConfig.module.preLoaders,
       postLoaders: [ { //delays coverage til after tests are run, fixing transpiled source coverage error
            test: /\.js$/,
            exclude: /(test|node_modules|bower_components)\//,
            loader: 'istanbul-instrumenter' } ],
      loaders: webpackConfig.module.loaders
    },
    plugins: webpackConfig.plugins.concat([new DefinePlugin({
      __karmaTestSpec: testFilesRegEx
    })]),
    resolve: webpackConfig.resolve,
    devtool: 'inline-source-map'      // Changed to allow the sourcemap loader to work: https://github.com/webpack/karma-webpack
  },    
  webpackServer: {
    noInfo: true
  },    
  singleRun: false,
  colors: true
};    
module.exports = karmaConfig;

I have tried exclude: /(test|node_modules|bower_components)// but it does not help.

How to exclude these files from the coverage report?

What is your config to set up coverage? – loganfsmyth Feb 21 '17 at 05:43 — loganfsmyth, Feb 21 '17 at 05:43

We can exclude folder/file using '!' notation. Example

 preprocessors: {
    'framework/**/!(node_modules|test|bower_components)/*.js': 'coverage'     
 }

For details refer - https://karma-runner.github.io/0.12/config/configuration-file.html

Removing the `/` in `webpack` `postLoaders` exclude helped in fixing the issue – Nidish K Viswanathan Feb 23 '17 at 03:18
I am working on windows env. So the `/` was the culprit – Nidish K Viswanathan Feb 24 '17 at 02:59
