Prove concept for testing apps

[shawninder]

This is about making a a working example exactly the way we want it, but it will involve adding features to this repo. Also see #3, which allows running the same test on live apps

Here is an example of testing language switching on the live ADM app:

'use strict'

var test = require('tape')
var Nightmare = require('nightmare')
require('nightmare-evaluate-async')(Nightmare)

function browse (url, fn, check) {
  return function (t) {
    var nm = Nightmare()
    nm.goto(url)
      .evaluateAsync(fn)
      .then((result) => {
        check(t, result)
        nm.end(function () {
          t.end()
        })
      })
  }
}

test('language', browse('http://tv.ae',
  function fn () {
    return new Promise(function (resolve, reject) {
      window.app.cases.$notloaded.once(function () {
        var originalValue = window.app.origin.discover.title.val
        window.app.origin.discover.title.once(function () {
          resolve(window.app.origin.discover.title.val !== originalValue)
        })
        window.app.api.language.set(window.app.origin.modals.languages.fields.arabic)
      })
    })
  },
  function check (t, result) {
    console.log('result', result)
    t.equal(result, true, 'language changed')
  }
))

This is not what we want in the end, just a first baby step.
