Karma-Jasmine

This file includes installation guide for Kama and Jasmine for testing angular application Getting Started with Karma for Tesing AngularJs: Karma provides realtime tests results while Changing code, But we need to refresh browser everytime when you make changes.

Karma - Test Runner

Jasmine - Testing Framework

Installing Karma/Jasmine enviournment:

First step is to install Node.js (Open terminal -> go to working dir)

create package.json

 $ echo {} >> package.json

(as you install following things then package.json file will update automatically)

Install Karma Tool:

 $ sudo npm install karma --save-dev

Install Karma Command Line Interface(Helps to run Karma command globally)

 $ npm install -g karma-cli

Install karma plug-ins to enable us to use the Jasmine test framework and Google Chrome

 $ sudo npm install karma-jasmine karma-chrome-launcher --save-dev

Install Jasmine Core

 $ sudo npm install karma-jasmine jasmine-core --save-dev

Now at this step we need to create karma config file.

 $ karma init

Then it will ask you for configuration :

Example:

Which testing framework do you want to use ?
  Press tab to list possible options. Enter to move to the next question.
  select--jasmine 
 Do you want to use Require.js ?
  This will add Require.js plugin.
  Press tab to list possible options. Enter to move to the next question.
  Select---no 
Do you want to capture any browsers automatically ?
  Press tab to list possible options. Enter empty string to move to the next question.
  Select browser-Chrome  
 What is the location of your source and test files ?
  You can use glob patterns, eg. "js/*.js" or "test/**/*Spec.js".
  Enter empty string to move to the next question.
  --press enter 
 Should any of the files included by the previous patterns be excluded ?
  You can use glob patterns, eg. "**/*.swp".
  Enter empty string to move to the next question.
  ----enter path of test files and your code
  03 05 2016 21:47:11.921:WARN [init]: Failed to install "karma-chrome-launcher". No permissions to write in /usr/local/lib!
  Please install it manually. 
Do you want Karma to watch all the files and run the tests on change ?
  Press tab to list possible options.
  ----select --yes

Config file will be generated ( karma.cong.js )

NOTE: press tab to see available options and press enter to more next qiestions, we can also edit karma.conf.js file later on

We may need to download download the angular and angular mock libraries

type:

[curl -o dir/angular.min.js https://code.angularjs.org/1.4.0-rc.2/angular.min.js]

[curl -o dir/angular-mocks.js https://code.angularjs.org/1.4.0-rc.2/angular-mocks.js]

Include above dir in to karma.conf.js

files: [
	'lib/angular.min.js',
  	'lib/angular-mocks.js',
	'app/*.js',
      	'test/**/*.js'
    ],

Install browser launcher manually (any one)

 $ chrome  - npm install karma-jasmine karma-chrome-launcher --save-dev 
 $ firefox - npm install karma-jasmine karma-firefox-launcher --save-dev 
 $ safari  - npm install karma-jasmine karma-safari-launcher --save-dev  
 $ phantomJS - npm install --save-dev karma-phantomjs-launcher

Now put your teste caes into /tests/ folder and application into /app/ folder and run karma

RUN karma

 $ karma start karma.conf.js
