使用 Karma (Jasmine) 测试 AngularJS 工厂

问题描述

我正在努力使用 Karma + Jasmine 测试 AngularJS 工厂.

I'm struggling with testing an AngularJS factory using Karma + Jasmine.

我无法将我的工厂注入到 OfficerValidationService 变量中.

I am unable to inject my factory to OfficerValidationService variable.

我做错了什么?

注意:文件加载正确

工厂:

'use strict';

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

  var OfficerValidationService = {};

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

  return OfficerValidationService;

}]);

代码:

'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:

推荐答案

需要调用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();
    });

  });
}());
