Karen is a collection of mock objects, for example window, document and node.
$ npm install karen --save-devThese are the main mock objects:
MockWindowMockDocumentMockElementMockNodeMockLocationMockNavigatorMockScreenMockDate
See code/tests for resp class on how to use.
As a simple example, let's say we want to add some syntactic sugar
around setTimeout, with the following API:
timer = Timer(window)
timer.delay 100, -> # do something
on 'event', ->
timer.stop()Here is the implementation of Timer:
Timer = (window) ->
delay: (ms, callback) ->
timeout = window.setTimeout(callback, ms)
stop: ->
window.clearTimeout(timeout)And a simple test using Mocha.js:
describe 'Timer', ->
it 'runs callback', (done) ->
mockWindow = new MockWindow
timer = Timer(mockWindow)
timer.delay(100, done)
mockWindow.tick(100)© 2014-2015 Burt AB, see LICENSE.txt (BSD 3-Clause).
