javascript - Unit test on Angularjs with Jasmine and Webpack, error Unknown provider -

i ask how solve error won't let me write test. angularjs factory (service.es6) test:

import rx 'rxjs/rx' var themiddlemodule = angular.module('themiddlemodule', []) themiddlemodule.factory('themiddleop', function ($http){   var api = 'someurl'   var themiddleop = {}    themiddleop.getssoidfromservice = () => {      return rx.observable.frompromise(         $http({             method: 'get',             url: api         })      )    }     return themiddleop }) 

this test webpack configuration:

var jasminewebpackplugin = require('jasmine-webpack-plugin'); module.exports = {   entry: ['./app/scripts/test/service.js'],   plugins: [new jasminewebpackplugin()],   output: {       path: __dirname,       filename: 'test.js'   },   module: {       loaders: [       {           test: /\.es6$/,           exclude: /(node_modules|bower_components)/,           loader: 'babel?presets[]=es2015!eslint-loader'       },       {           test: /\.js$/,           exclude: /(node_modules|bower_components)/,           loader: 'babel?presets[]=es2015!eslint-loader'       }   ]   }  } }; 

and js test file:

import 'angular'; import 'angular-mocks'; import '../services/service.es6';  var service;  describe('service test', function() {     var $httpbackend, $httpprovider;     var module = angular.mock.module();     var url = 'someurl';      beforeeach(function () {          module('themiddlemodule');          inject(function ( _$httpbackend_, _themiddleop_) {             $httpbackend = _$httpbackend_;             service = _themiddleop_;              $httpbackend.when('post', url)             .respond(200, {'sso-id':'test'});         });     });      it('$httpbackend should defined', function (){         expect($httpbackend).tobedefined();     });      it('themiddleop should defined', function (){         expect(service).tobedefined();     });      it('should call ssoid service', function (){         var getfromservice = service.getssoidfromservice()         getfromservice.subscribe(             (response) => {},             (e) => {},             () => {                 $httpbackend.expectget(url);                 $httpbackend.flush();             }         )     });      aftereach(function() {         $httpbackend.verifynooutstandingexpectation();         $httpbackend.verifynooutstandingrequest();     }); }); 

the error jasmine gives me is:

error: [$injector:unpr] unknown provider: themiddleopprovider <- themiddleop 

if comment row:

service = _themiddleop_; 

the $httpbackend test passes correctly , fails others, of course. tried import service.es6 without export, module default export , more combinations. in advance give me.

it looks module not defined. because factory registered module. error in module definition.

there 3 things wrong if may guess:

var module = angular.mock.module(); 

why needed? why not write angular.mock.module in before each?

angular.mock.module('themiddlemodule'); 

the other option factory , choice of variables. suggestion rewrite followed:

angular.module('themiddlemodule', [])   .factory('themiddleop', function ($http){     var api = 'someurl';      return {      getssoidfromservice = () => {         return rx.observable.frompromise(           $http({             method: 'get',             url: api         });      )     };   }); 

the last option webpack configuration wrong. can debug test configure not singlerun;

last comment, unit test not testing anything; , remove check if $httpbackend there because testing angular mock working?
