• Sinon
• Chai
• Sinon-Chai

for Karma

Requirements

This module currently requires the canary version of Karma:

$ npm install 'karma@canary' --save-dev

Note that the Karma configuration file format has changed since v0.8. Use karma init to generate a fresh config.

Grunt

When using grunt-karma to run Karma, you need to use a version >= 0.5.0 because earlier versions of grunt-karma use karma < 0.9 which does not support custom plugins. At the time of this writing, grunt-karma >= 0.5 is not yet available on npm, so you have to install it directly from the git repo, i.e.

npm install --save-dev git+https://github.com/karma-runner/grunt-karma.git

Installation

Install the module from Github:

$ npm install 'git+https://github.com/xdissent/karma-chai.git' --save-dev

Add chai to the frameworks key in your Karma configuration:

module.exports = (karma) ->
  karma.configure

    # frameworks to use
    frameworks: ['mocha', 'chai']

    # ...

Usage

Each of the different Chai assertion suites is available in the tests:

describe 'karma tests with chai', ->

  it 'should expose the Chai assert method', ->
    assert.ok('everything', 'everything is ok');

  it 'should expose the Chai expect method', ->
    expect('foo').to.not.equal 'bar'

  it 'should expose the Chai should property', ->
    1.should.not.equal 2
    should.exist 123

Sinon and Chai matchers for Sinon are also available:

describe 'karma tests with sinon', ->

  it 'can spy on objects', ->
    foo = bar: ->
    sinon.spy foo, 'bar'

    foo.bar 'baz'

    foo.bar.should.have.been.calledWith 'baz'
