Service not defining when injecting it for Karma testing - AngularJS -

i've seen few of these questions on internet, none of answers seem solve problem. have service works in served app, when test in karma not being defined.

i've got modules , associated controllers, directives , services in src folder. structure of file follows:

angular.module('cst-error-framework', ['md.alerts', 'md.input', 'md.modals']);  angular.module('md.alerts', [])     .directive(//..associated directives here  angular.module('md.input', [])     //blah blah blah  angular.module('md.modals', [])     //directives , controllers     .factory('mderrorhandler', function () {         //contents here     }); 

i know seems bit cumbersome there other reasons have in 1 file.

then spec mderrorhandler follows:

describe('service errorhandler', function () {  beforeeach(function() {     module('cst-error-framework');     angular.mock.module('templates'); }); var mderrorhandler;  beforeeach(inject(function(_mderrorhandler_){     mderrorhandler = _mderrorhandler_;     console.log(mderrorhandler); })); 

here karma.conf.js:

module.exports = function(config) {   config.set({     basepath: '',     frameworks: ['jasmine'],     files: [      'bower_components/jquery/dist/jquery.js',      'bower_components/angular/angular.js',      'bower_components/angular-sanitize/angular-sanitize.js',      'bower_components/angular-mocks/angular-mocks.js',       'dist/cst-error-framework.js',      'dist/cst-error-framework.css',       'src/**/templates/*.html',      'src/helpers/*.js',      'src/**/test/*.spec.js'     ],     preprocessors : {      'src/**/templates/*.html': 'ng-html2js'    },     nghtml2jspreprocessor: {      stripprefix: 'src/',      modulename: 'templates'    },     exclude: [],     port: 9876,     loglevel: config.log_info,     autowatch: true,     browsers: [process.env.travis ? 'firefox' : 'chrome'],     singlerun: false   });   'use strict';   }; 

then when run karma tests, mderrorhandler not being defined, result of console.log [].

any idea what's going on? order karma loading stuff? avoid having refactor main .js file.

edit starting suspect maybe in gulpfile causing issues? here karma gulp task:

gulp.task('karma', ['build'], function(done) {  karma.start({    configfile: __dirname + '/karma.conf.js',    singlerun: true  }, done); }); 

when instantiate module in test, don't need function declaration.

so instead of

beforeeach(function() {     module('cst-error-framework');     angular.mock.module('templates'); }); 

try

beforeeach(module('cst-error-framework'); beforeeach(angular.mock.module('templates');
