karma-jasmine-jquery

Jasmine-jquery plugin for Jasmine in Karma.

It karma adapter for

Installation

Install the plugin from npm:

$ npm install karma-jasmine-jquery

Attention

karma-jasmine-jquery has a dependency on jasmine, so you should use karma-jasmine as well before karma-jasmine-jquery. Please note the followings.

This plugin will only work for version karma-jasmine 2.0 and above.

Usage

karma will autoload all plugins, whose name start with karma-, you can import karma-jasmine-jquery plugins manually. Please refer to http://karma-runner.github.io/0.12/config/plugins.htmt for more details.

// karma.conf.js
module.exports = function(config) {
  config.set({

      frameworks: ['jasmine-jquery','jasmine']
      //...
   })
}

The order(‘jasmine-jquery’,‘jasmine’) is important since it affects the order in which the files will be included to karma. Right order - reverse as karma works on the principle of LIFO stack.

Information

This plugin already includes jquery version 2.1.1, it is used for the plugin. However, in the project, you can use a version of jquery (it can be both below and above) and they will not interfere with each other. When writing tests using jquery $ for the project, and to use jquery 2.1.1, use a global variable $j (it makes sense when you want to use when writing test jquery 2 opportunities that are not available in the current version of jquery used in your project, as I). Example of use:

// karma.conf.js
module.exports = function(config) {
  config.set({

      frameworks: ['jquery-1.3.2', 'jasmine-jquery', 'jasmine'],
      //...
   })
}

// Jasmine test example

it('test1', function() {
    $().destroyWin('window'); // jquery 1.3.2
    expect($j('#window')).not.toBeInDOM(); // $j = jquery 2.1.1
  });
