这是我对 AngularJS 指令的第一次测试,我可能遗漏了一些非常基本的东西。

运行我的测试套件时,在调用 $compile 函数后出现错误:当它试图评估urlIsSameOrigin是否:

TypeError:'undefined' 不是对象(评估 'parsed.protocol')

tableDirective.js 指令

https://gist.github.com/jdreimann/a5076363f1d8f3a605a0

tableDirective.js 测试

'use strict';

describe('Directive: TableDirective', function() {

  var $rootScope,
  $compile,
  elmBody;

  beforeEach(module('wdUiCoreApp'));

  beforeEach(inject(function (_$compile_ , _$rootScope_) {
    $compile = _$compile_;
    $rootScope = _$rootScope_;
    elmBody = angular.element(
      '<div ui-core-table><div class="panel__header"></div></div>'
    );

    $compile(elmBody)($rootScope);
    scope.$digest();
  }));    

  describe('elmBody', function () {
    it('should be an object', function() {
      expect(elmBody).toEqual(jasmine.any(Object));
    });
  });

问题是该指令通过返回元素属性uiCoreTable值的函数定义了它的模板 URL 。template

由于您的测试代码没有指定template属性,因此模板 URL 未定义,并且在 Angular 尝试从服务器请求模板 URL 时会引发错误。
更具体地说,$http服务的一项安全检查引发异常:检查protocolURL 的测试尝试访问parsed.protocol,但parsed未定义(因为templateUrl未定义)。


如果现在还不明显,为了使错误消失,您需要在template属性中指定模板 URL。例如:

elmBody = angular.element('<div ui-core-table template="/path/to/template.html">...</div>');

如果您不想向服务器发出实际请求,您可以$templateCache使用一些 HTML(在 key 下)预先填充,或者在请求目标时使用自定义响应/path/to/template.html训练模拟对象。 $httpBackend/path/to/template.html
