Animation And Testing In Angular JS
2. Slide 2 www.edureka.co/angular-jsSlide 2
Objectives
At the end of this module, you will be able to understand:
Two Way Data Binding
AngularUI for User Interface
ngAnimate for Animation
Testing in AngularJS
3. Slide 3 www.edureka.co/angular-jsSlide 3
Controllers in AngularJS define the workflow presentation logic
A JavaScript object
Created by a standard JavaScript object constructor
Attached to the view with ng-controller
Controllers can be defined in the application as shown
<div ng-controller=“MyController">
<body ng-controller=“MyController">
Controllers
Defining Controller
Using Controller in application
var myApp = angular.module('myApp',[]);
myApp.controller(‘MyController'.......
4. Slide 4 www.edureka.co/angular-jsSlide 4
Injected as an argument to the controller function
Holds the model data required by the view
Binds data to the view using AngularJS two way data binding
Represented by $scope in the controller function and links the controller to the view
Figure shown is representation of scope
app.controller(‘MyController', ['$scope',
function($scope) {
…………………..
]};
}]);

MODEL
AngularJS is a model driven application
A Model encapsulates the application data
Any change in the state, provides appropriate notifications to the controller and views
On notification views updates the output display of the application
Updating of view happens automatically with data bindings
TEMPLATE
Represents the model in the view and user interactions with application
Model and Template

AngularUI for User Interface
In normal jQuery application, we will be including bootstrap js files to access the bootstrap functionalities like modal,
accordion, datepicker, etc.,
We will be doing dom traversing to bind the event with dom element in jQuery.
Instead of doing DOM traversing, we will be creating custom directives in AngularJS to bind the events.
Angular UI will be having special set of directives to achieve bootstrap functionalities in angularJS app.
10. Slide 10 www.edureka.co/angular-js
How to use AngularUI
Download required javascript, css files and include those in main html.
In angular module declare a ui.bootstrap as a dependency to your angular App.
e.g : - angular.module( ‘demo’ , ['ui.bootstrap'] );
ui.bootstrap module will be having all bootstrap functionalities as directives and services. Once it is injected into our
application, we can access all the bootstrap modules.
11. Slide 11 www.edureka.co/angular-js
ngAnimate for Animation
The ngAnimate module provides support for CSS-based animations as well as JavaScript-based animations.
Animations are not available unless you include the ngAnimate module as a dependency within your
application.
ngAnimate can be used with various directives like ngRepeat, ngView, ngInclude, ngIf, ngMessage etc.
12. Slide 12 www.edureka.co/angular-js
How to use ngAnimate
Download and include ng-animate js file to main html.
Add ngAnimate as a dependency to angular application.
e.g : angular.module( ‘demo’ , ['ngAnimate'] );
13. Slide 13 www.edureka.co/angular-js
How it works
Once ngAnimate injected we can use animations by using CSS or JavaScript.
For both CSS and JS animations the sole requirement is to have a matching CSS class that exists both in the
registered animation and within the HTML element that the animation will be triggered on.
ngAnimate is supported in following modules : ngRepeat, ngShow, ngHide, ngIf, ng-view etc.
CSS based animation :
CSS-based animations require no JavaScript code. By using a CSS class that we reference between our HTML
and CSS code we can create an animation that will be picked up by Angular when an the underlying directive
performs an operation.
JavaScript based animation :
ngAnimate also allows for animations to be consumed by JavaScript code. By making use of the
module.animation() module function we can register the animation.

Manual Testing
Traditionally developers manually test their application
Manual testing is less efficient
Very difficult to track the test result
Very difficult to test all the pieces of code
Very difficult to test the integration of two ore more functions
Differs from one developer to another developer
