Simple Javascript Testing
=========================

Simple javascript testing for rails templates with phantomjs.

This library adds the method call_template_with_js to your tests, if you include SimpleJavascriptTesting.
This method builds the template you specify (ie users/index) and runs the javascript test file (test/javascript/users/index.js) against it. It stubs out any AJAX calls.

example ruby test test/phantomjs/template_test.rb:
``ruby

require 'test_helper'
require 'simple_javascript_testing'

class TemplateTest < ActiveSupport::TestCase
include SimpleJavascriptTesting

def test_users_index
call_template_with_js "users/index"
end

def test_dwarves_show
civilization = Civilization.find_or_create_by :id => 100
dwarf = civilization.dwarves.find_or_create_by :id => 10
call_template_with_js "dwarves/show" do |data|
data.set_instance_variable "dwarf", dwarf
end
end
end
`

and example js test file test/javascript/users/index.js:
`js
var simple = require('simple_javascript_testing')

simple.runTest("test file", function(page) {
var checked = page.evaluate(function() {
triggerRequest("/df/artery/user.json", {Id: 1, Name: "Hey", Thoughts: "hey"})
triggerRequest("/df/artery/user/get_unit_labors.json", [{Labor: 1}])
assertAllRequestsRun()
return document.querySelector('#labor_1').checked
})
this.assert_equal(true, checked)
})

`
triggerRequest will manually trigger the callback for an AJAX request with the response you specify.
page is the phantomjs object
