Angularjs 错误：[$injector:modulerr]在Karma上

我是一个新手来测试卡玛和摩卡。我想在以下控制器上进行单元测试：

'use strict';

// common functionality
angular.module('app').controller('CommonCtrl', ['$scope', 'appConfig',
  function ($scope, appConfig) {
    $scope.$back = function() {
    window.history.back();
  };

  $scope.Currencies = appConfig.currencies;

  // todo: decide where this should go (appConfig?)
  $scope.ctPaginationLabel = {
    text: 'Einträge pro Seite:',
    of: 'von'
  }
}]);

这就是我的测试类的外观：

describe 'CommonCtrl', ->
  $controller = null    

  beforeEach ->
    module 'app'
    inject (_$controller_) ->
      $controller = _$controller_

  it 'error flag if scope is missing', ->
    $scope = null
    appConfig = null
    controller = $controller 'CommonCtrl', { $scope: $scope, appConfig: appConfig }
    controller.error.should.be.ok

但我得到了以下错误：

我在karma.conf.js中嵌入了所有依赖项。我的测试类中的错误在哪里？

您在哪里定义了“应用”模块？angular.module（'app'，[]）？并可能使用类似-module（函数（$provide）{$provide.value（'appConfig'，null）；//重写注入的依赖项}）; 在“it”块中。应在此处定义“app”模块：我在

it

块中插入了

module（$provide）->$provide.value“appConfig”，返回null

，但它不能解决问题
