Hey man, I'm facing the same problem.. can you provide just for testing you backbone view code ?
does it looks like this one?
var Backbone = require("Backbone");
Template = require("templatePath"),
$ = require("jquery");
Backbone.$ = $;
module.exports = Backbone.View.extend({
//view
});
@renancarvalho Did you manage to hack it?

I have found the problem. Something that probably was escaping me was that jsdom creates a DOM instance (window and its friends). At this point, it needs to have the necessary scripts that you may need e.g. jquery. So I have to define
$within the DOM instance. Here is a solution that works:and boom!
The downside to this IMO is that I had to use a local copy in scripts directory in my test folder.
This is my setup because eventually I want to
browserifymy app.@todo: Look for a way to reference from the jquery
distdirectory so that whenever Inpm updatejquery my test suite does not fall behind if I forget to copy the new distro in the scripts folder which is highly likely.
