unit testing - AngularJS + Karma + Jasmine + Karma-Coverage: Empty coverage report -

i'm trying integrate current angularjs project karma coverage. please find below package.json , karma-config.

package.json

{   "name": "project",   "description": "description",   "repository": "https://www.repo.com",   "devdependencies": {     "karma": "~0.10.9",     "karma-junit-reporter": "~0.2.1",     "karma-jasmine": "~0.1.5",     "karma-ng-scenario": "~0.1",     "karma-script-launcher": "~0.1.0",     "karma-chrome-launcher": "~0.1.3",     "karma-firefox-launcher": "~0.1.3",     "karma-phantomjs-launcher": "~0.1.4",     "karma-ng-html2js-preprocessor": "~0.1",     "karma-coverage": "~0.1"   } } 

karma config

'use strict';  module.exports = function (config) {   config.set({     basepath: '../../public/',     loglevel: config.log_debug,     frameworks: ['jasmine'],     singlerun: true,     files: [         'libs/jquery/jquery-1.9.0.js',         'libs/angular/1.2.10/angular.js',         'libs/angular/**/*.js',         'libs/angular/*.js',         'libs/vendor/*.js',         'libs/test/**/*.js',          // fixtures         {pattern: 'test/mock-data/helloworld/*.json', watched: true, served: true, included: false},          'apps/helloworld/**/*.js',         'apps/helloworld/*.js',         'test/helloworld/unit/**/*.js',         'test/helloworld/*.js',         'views/helloworld/directives/*.html'     ],      exclude: [         'libs/angular/1.2.10/*.min.js',         'libs/angular/angular-animate.js'     ],      browsers: ['phantomjs'],      reporters: ['progress', 'junit', 'coverage'],      preprocessor: {         'apps/helloworld/**/*.js': ['coverage'],         '*.html': ['ng-html2js']     }   }) }; 

when try run "node_modules/.bin/karma start conf/advisor/karma.conf.js" tests run karma-coverage report empty. i've tried couple of options cannot make reports appear.

the console output never runs preprocessor coverage. can see runs html2js.

question: doing wrong here? how make karma coverage load src js files?

you missing preprocessors property , coveragereporter property.

add section karma config file:

preprocessors: {       'apps/helloworld/**/*.js':['coverage']    }, coveragereporter:{       type:'html',       dir:'c:/dev/coverage/'    }, 

you can change coveragereporter output directory whatever want.
