使用Karma（Jasmine）测试AngularJS工厂

angularjs

我正在努力使用Karma + Jasmine测试AngularJS工厂。

我无法将工厂注入OfficerValidationService变量。

我究竟做错了什么？

注意：文件已正确加载

厂：

'use strict';

angular.module('darthvader').factory('OfficerValidationService', [function(){

  var OfficerValidationService = {};

  OfficerValidationService.something = function() {
    return true;
  };

  return OfficerValidationService;

}]);

码：

'use strict';

(function() {
  describe('OfficerValidationService Spec', function() {

    var OfficerValidationService;

    beforeEach(function() {
      angular.module('darthvader');
    });

    beforeEach(module('darthvader', function($provide) {
      $provide.value('OfficerValidationService', OfficerValidationService);
    }));

    it('is very true', inject(function(OfficerValidationService){
      alert('=====' + OfficerValidationService + '=====');
      var output = OfficerValidationService.something();
      expect(output).toBeTruthy();
    }));

  });
}());

输出：

您需要致电angular.injector：

'use strict';

(function() {
  describe('OfficerValidationService Spec', function() {

    var OfficerValidationService;

    beforeEach(function() {
      angular.module('darthvader');
    });

    beforeEach(inject(function() {
      var $injector = angular.injector(['darthvader']);
      OfficerValidationService = $injector.get('OfficerValidationService');
    }));

    it('is very true', function(){
      var output = OfficerValidationService.something();
      expect(output).toBeTruthy();
    });

  });
}());
