Question

我正在尝试将服务注入到Angular单元测试用例中，但是会出现此错误，

[$ injector：unpr] http://errors.angularjs.org/1.4.7/ $ injector / unpr？p0 = FactsSvcProvider％20％3C-％20FactsSvc

我理解错误，我无法弄明白为什么它无法解决依赖？

以下是代码片段

app.js

    angular.module('numberApp', ['ngAnimate', 'ngResource', 'ui.router', 'ngMock'])
    .config(function($stateProvider, $urlRouterProvider, $httpProvider) {
//config code...
})

事实-controller.spec.js

describe('Test Controller', function () {
  var scope, controller, FactsSvc, $q;

  beforeEach(function() {
    angular.module('numberApp', ['ngAnimate', 'ngResource', 'ui.router', 'ngMock']);
  });

  beforeEach(inject(function (_$rootScope_, $controller, _$q_, _factsSvc_) {
    scope = _$rootScope_.$new();
    $q = _$q_;
    FactsSvc = _factsSvc_;
    controller = $controller('factsCtrl', {
      $scope: scope,
      FactsSvc: FactsSvc
    });
  }));

  it('should call the generateMathFacts method in facts service to' +
      ' retrieve the facts',
    function() {
      var num = 20,
        response = {
          text: 'This is a fact'
        },
      dfd = $q.defer(),
      promise = dfd.promise();

      dfd.resolve(response);
      spyOn(FactsSvc, 'getMathFacts').andReturns(promise);

      scope.generateMathFact(num);
      expect(FactsSvc.getMathFacts).toHaveBeenCalled();
    });
});

我收到此错误

控制器代码

"use strict"

angular.module('numberApp')
.controller('factsCtrl', function($scope, factsSvc, message, $rootScope) {
//logic...
})

服务代码

"use strict"

angular.module('numberApp')
.service('factsSvc', function($resource, resourceAPI) {
//logic...
}

请任何帮助将不胜感激。

在使用jasmine进行单元测试期间将服务注入控制器时，会出现未知的提供程序错误
