What kind of "integration testing" do you mean ?

Is Ember.js community tight to QUnit ? For instance, is there much better integration with Ember.js + QUnit ? Because I personally think Jasmine's syntax is superior to QUnit - that's just my personal experience and I don't wanna force anybody to use any framework, but it sounds lame to "recommend" QUnit, so I'd prefer to at least mention "or any other testing framework you like".
