Question

我有一个服务，我为我正在进行的项目编写，我正在尝试为它编写单元测试。以下是服务的代码

angular.module('services').factory('Authorization', ['$q', 'Refs', function($q, Refs) {

  function isAuthorized() {
    var deferred = $q.defer();

    var authData = Refs.rootRef.getAuth();
    var adminRef;

    if(authData.google) {
      adminRef = Refs.rootRef.child('admins').child(authData.uid);
    } else {
      adminRef = Refs.rootRef.child('admins').child(authData.auth.uid);
    }

    adminRef.on('value', function(adminSnap) {
      deferred.resolve(adminSnap.val());
    });
    return deferred.promise;
  }

  return {
    isAuthorized: isAuthorized
  };
}]);

我已经为它编写了一个单元测试，但是无论何时我运行测试，我都会收到此错误消息＆＃39;错误：超时 - 在jasmine.DEFAULT_TIMEOUT_INTERVAL指定的超时时间内未调用异步回调。＆＃39;

以下是我为该服务编写的单元测试的代码：

'use strict';

describe('Authorization Service', function() {

  var Refs, $q, Authorization, authData, scope, deferred;

  beforeEach(angular.mock.module('Sidetime'));

  beforeEach(inject(function(_Refs_, $rootScope, _$q_, _Authorization_) {
    Refs = _Refs_;
    $q = _$q_;
    Authorization = _Authorization_;
  }));

  iit('return admin object', function(done) {
    var result;

    Authorization.isAuthorized = function() {
      deferred = $q.defer();
      authData = {google: 'uid:112222'};

      if(authData.google) {
        deferred.resolve(authData);
      }

      return deferred.promise;
    };

    Authorization.isAuthorized().then(function(result) { 
      console.log('result', result);
      expect(result).toEqual(authData);
      //done();
    });
  });
});

我不确定我是否正确编写单元测试。如果有人能够更好地为这项服务编写单元测试，我将不胜感激。感谢您的预期帮助。

这是一个工作的plunker，略有修改，因为我没有所有依赖项的代码：

 angular.module('services', []).factory('Authorization', ['$q', function($q) {

  function isAuthorized() {
    var deferred = $q.defer();

    deferred.resolve({authData: {google: 'uid: 1122222'}});
    return deferred.promise;
  }

  return {
    isAuthorized: isAuthorized
  };
}]);


describe('Authorization Service', function() {

  var  $q, Authorization, scope, deferred;

  beforeEach(angular.mock.module('services'));

  beforeEach(inject(function($rootScope, _$q_, _Authorization_) {
    $q = _$q_;
    scope = $rootScope.$new();
    Authorization = _Authorization_;

    Authorization.isAuthorized = function() {
      deferred = $q.defer();
      authData = {google: 'uid:112222'};

      if(authData.google) {
        deferred.resolve(authData);
      }

      return deferred.promise;
    };
  }));

  it('return admin object', function(done) {
    var result;

    var promise = Authorization.isAuthorized();

    promise.then(function(result) {
      expect(result).toEqual(authData);
      expect(result.google).toEqual('uid:112222e');
    });

    deferred.resolve(result);
    scope.$digest();


  });
});



(function() {
  var jasmineEnv = jasmine.getEnv();
  jasmineEnv.updateInterval = 250;

  /**
   Create the `HTMLReporter`, which Jasmine calls to provide results of each spec and each suite. The Reporter is responsible for presenting results to the user.
   */
  var htmlReporter = new jasmine.HtmlReporter();
  jasmineEnv.addReporter(htmlReporter);

  /**
   Delegate filtering of specs to the reporter. Allows for clicking on single suites or specs in the results to only run a subset of the suite.
   */
  jasmineEnv.specFilter = function(spec) {
    return htmlReporter.specFilter(spec);
  };

  /**
   Run all of the tests when the page finishes loading - and make sure to run any previous `onload` handler

   ### Test Results

   Scroll down to see the results of all of these specs.
   */
  var currentWindowOnload = window.onload;
  window.onload = function() {
    if (currentWindowOnload) {
      currentWindowOnload();
    }

    //document.querySelector('.version').innerHTML = jasmineEnv.versionString();
    execJasmine();
  };

  function execJasmine() {
    jasmineEnv.execute();
  }
})();

请查看spies in jasmine以获得更深入的介绍

我采用了Cognitroics plunkr并以我通常编写测试的方式对其进行了修改。在这里查看http://plnkr.co/edit/W5pP82CKj7tc6IO3Wj9S?p=preview

但基本上你应该做的就是利用茉莉花中间谍的精彩。

这是它的样子。

describe('My aweomse test suite', function(){
    beforeEach(function(){
        module('Awesome');
        inject(function($injector){
           this.MyService = $injector.get('MyService');
           this.$q = $injector.get('$q');
           this.$scope = $injector.get('$rootScope').$new();

           spyOn(this.MyService, 'someMethod').andCallFake(function(){
              var defer = this.$q.defer();
              defer.resolve();
              return defer.promise;
           });
        });

        it('should do seomthing', function(){
            // given
            var result;

            // when
            this.MyServcie.someMethod().then(function(){
                result = 'as promised';
            });

            this.$scope.$digest();

            // then
            expect(result).toEqual('as promised');
        });
    });
});

承诺服务的单元测试
