Rspec, Poltergeist, Capybara not working with audio files

Question

Using rspec-rails-3.5.2, poltergeist-1.11.0, and capybara-2.10.1

I created an audio object:

Bart.pumpAudio = new Audio("assets/audio/bart/pump.mp3");

I have a button that plays a sound when pressed

<div id="pump-button" class="button">Pump</div>

$("#pump-button").click(function() {
    ...
    Bart.pumpAudio.play();
    ...
});

It works when I run on a browser, but I get errors when trying to perform tests through rspec:

Testing Code:

page.find("#pump-button").trigger('click')

Testing Error:

TypeError: 'undefined' is not a function (evaluating 'Bart.pumpAudio.play()')

Any ideas on how to solve this??

Answer 1

Adding this to the top of my js file seemed to solve my issue

var Audio = function() {
    return {
        load: function() {},
        play: function() {}
    }
}
