AngularJS单元测试Karma - 未知提供商

问题描述 投票:1回答:1

我正在尝试在我们的传统AngularJS应用程序上设置单元测试。我使用标准业力和angular-mock来设置测试用例。但是当我尝试注入一些服务和工厂时,我遇到了Unknown provider的问题。我的karma.conf看起来像这样(为了简洁,我删除了很多东西)

module.exports = function(config) {   config.set({

     basePath: '',

     // frameworks to use
     // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
     frameworks: ['jasmine'],

     // list of files / patterns to load in the browser
     files: [
       './node_modules/angular/angular.js',
       "http://cf._____.com/content/myfootprints/js/priorityqueue.js",
       "http://cf._____.com/content/myfootprints/js/ng-flow-standalone.js",
       INCLUDED ALL THE DEPENDENCIES HERE 
       './node_modules/angular-mocks/angular-mocks.js',
       './static/js/app/main.js',
       './static/tests/**/*.js'
     ]
     preprocessors: {
       './static/js/app/**/main.js':['webpack', 'sourcemap'],
       './static/js/app/**/*.js':['webpack', 'sourcemap'],
     },

在我们的应用程序中,我们有一个main.js,它使用importsrequireDir将所有控制器和工厂导入应用程序。它看起来像这样

const requireDir = require('webpack-requiredir');

    import './isocurrency.js';
    import './myfp_uirouter.js';
    import './infobubble.js';
    // other imports
    requireDir(require.context('./controllers', true, /.*\.js$/))
    requireDir(require.context('./directives', true, /.*\.js$/))
    requireDir(require.context('./factories', true, /.*\.js$/))
    requireDir(require.context('./filters', true, /.*\.js$/))

我有一个单元测试文件看起来像这样

describe('Unit test file, function(){
  var generalUtilFactory;
  beforeEach(inject(function($injector){
    generalUtilFactory = $injector.get('generalUtilsFactory'); <--- getting unknown provider 
    // Also tried to inject it in 
    //via function($rootScope,... _generalUtilFactory_)
  }));

Other code
  .
  .
  .
  .

});

现在我有通过main.js导入的一般工厂工厂,并在app模块中注册。我检查过在调试器中看到它。看起来像这样

angular.module('app').factory('generalUtilsFactory', ['$timeout', '$filter', 'FileSaver', 'Blob', function($timeout, $filter, FileSaver, Blob) {
    var generalUtilsFactory = {};

    generalUtilsFactory.getKeys = function(o){

我不太清楚这里发生了什么。已包含所有需要的文件,并且所有es6都已正确转换。我们将不胜感激

我认为你需要在注入服务之前注入主模块。也许做这样的事情会有所帮助:

describe('Service Tests', function () {
    beforeEach(module('app'));
    var _generalUtilsFactory;

    beforeEach(inject(function (generalUtilsFactory) {
        _generalUtilsFactory = generalUtilsFactory
    }));
});
