javascript – 如何在AngularJS 1.3.15中同步测试动画?

前端之家收集整理的这篇文章主要介绍了javascript – 如何在AngularJS 1.3.15中同步测试动画?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我想我有一个迁移问题与角度animate.js从版本1.2到1.3.
这是我的动画
'use strict';
angular.module('cookbook',['ngAnimate'])
    .animation('.slide-down',function() {
        var NG_HIDE_CLASS = 'ng-hide';

        return {
            beforeAddClass: function(element,className,done) {
                alert('before add');
                if(className === NG_HIDE_CLASS) {
                    element.slideUp(done);
                }
            },removeClass: function(element,done) {
                if(className === NG_HIDE_CLASS) {
                    element.hide().slideDown(done);
                }
            }
        };
    });

同步测试

'use strict';

describe('A Brief Look At Testing Animations(changed) - ',function() {
    var scope;
    var element;
    var $animate;
    var $rootElement;

    beforeEach(module('cookbook','ngAnimateMock'));

    describe('Synchronous testing of animations',function() {

        var animatedShow = false;
        var animatedHide = false;

        beforeEach(module(function($animateProvider) {
            $animateProvider.register('.slide-down',function() {
                return {
                    beforeAddClass: function(element,done) {
                        debugger;alert(1);
                        animatedHide = true;
                        done();
                    },done) {
                        animatedShow = true;
                        done();
                    }
                };
            });
        }));

        beforeEach(inject(function($injector) {
            scope = $injector.get('$rootScope').$new();
            $rootElement = $injector.get('$rootElement');
        }));

        beforeEach(inject(function($compile) {
            element = angular.element('<div class="slide-down" ng-show="hint"></div>');
            $compile(element)(scope);
            scope.$digest();
            $rootElement.append(element);
        }));

        it('should animate to show',function() {
            scope.hint = true;
            scope.$digest();
            expect(animatedShow).toBeTruthy();
        });

        it('should animate to hide',function() {
            scope.hint = true;
            scope.$digest();
            scope.hint = false;
            scope.$digest();
            expect(animatedHide).toBeTruthy();
        });

    });
});

和规格赛

当我使用角度动画1.2.28时,所有的测试都会通过,但是在切换到1.3.15测试失败之后.现在,我正在调查两个版本的角动画之间的区别.也许有人有这个麻烦.感谢大家的答案.

解决方法

在试图让测试工作时,我意识到我只能:

>从$animate使用addClass和removeClass来添加/删除ng-hide类;直接用“ng-show”没用.当使用这些方法时,我意识到从注册为动画的对象中的方法“removeClass”从未被调用,被调用方法是:“beforeAddClass”和“beforeRemoveClass”,所以我改变了这一点.当我谷歌关于它,我发现一个问题有点相关:$animate.removeClass() doesn’t work if addClass animation incomplete.
>使用rootScope而不是范围(我不明白为什么)

搜索一点以后,我发现这个comment在一个问题上;似乎有一些bug与动画;该评论建议使用角度和角度动画的不同版本,因为“流水线中有一些错误修正”.所以我尝试使用更新版本(v1.4.0-build.4010 sha.213c2a7),现在似乎工作更好…使用ng-show指令现在可以工作. (但是只有beforeAddClass和beforeRemoveClass才被调用,并且无法获取作用范围…).

我不是建议你升级(即使是因为v.1.4.0还没有发布),只是指出这个主题有问题和错误…)
这是代码(建议版本v1.4.0-build.4010):

describe('animate',function() {
  var scope,$animate,$rootElement,$compile,$rootscope;

  describe('Synchronous testing of animations',function() {

    var animatedShow = false;
    var animatedHide = false;

    beforeEach(module('cookbook',function( $animateProvider ) {
      animatedShow = false;
      animatedHide = false;

      $animateProvider.register('.slide-down',function() {
        return {
          beforeAddClass: function( element,done ) {
            animatedHide = true;
            done();
          },beforeRemoveClass: function( element,done ) {
            animatedShow = true;
            done();
          }
        };
      });
    }));
    beforeEach(inject(function( _$injector_,_$animate_,_$compile_ ) {
      $compile = _$compile_;
      $animate = _$animate_;
      $rootscope = _$injector_.get('$rootScope');
      scope = _$injector_.get('$rootScope').$new();
      $rootElement = _$injector_.get('$rootElement');
    }));
    it('should animate to hide',function() {
      $rootscope.hint = true;
      var el = $compile('<div class="slide-down" ng-show="hint"></div>')($rootscope);
      $rootElement.append(el);
      angular.element(document.body).append($rootElement);
      $rootscope.$digest();
      $rootscope.hint = false;
      $rootscope.$digest();
      expect(animatedHide).toBeTruthy();
    });
    it('should animate to show',function() {
      $rootscope.hint = false;
      var el = $compile('<div class="slide-down" ng-show="hint"></div>')($rootscope);
      $rootElement.append(el);
      angular.element(document.body).append($rootElement);
      $rootscope.$digest();
      $rootscope.hint = true;
      $rootscope.$digest();
      expect(animatedShow).toBeTruthy();
    });
  });
});

我也同意这个测试没有测试真正的动画代码;也许e2e测试应该更好.

这里是使用角度和角度动画v1.3.15的代码,直接使用addClass和removeClass:

//...the rest of code is identical

    it('should animate to hide',function() {
      var el = $compile('<div class="slide-down"></div>')($rootscope);
      $rootElement.append(el);
      angular.element(document.body).append($rootElement);
      $rootscope.$digest();
      $animate.addClass(el,'ng-hide');
      $rootscope.$digest();
      expect(animatedHide).toBeTruthy();
    });
    it('should animate to show',function() {
      var el = $compile('<div class="slide-down ng-hide"></div>')($rootscope);
      $rootElement.append(el);
      angular.element(document.body).append($rootElement);
      $rootscope.$digest();
      $animate.removeClass(el,'ng-hide');
      $rootscope.$digest();
      expect(animatedShow).toBeTruthy();
    });
    //...

我希望这有助于…谢谢.
