I'm trying to start unit testing (not using any testing frameworks) for my javascripts. Here's one example of it. var obj = {};obj.disableBtn = function ($btn, style) {  $btn.attr('disabled','disabled').addClass('disabled').removeClass(style);};The use case is as such:obj.disableBtn($('.submit'), 'btn-blue');What it does is simply add the disabled attribute, add the disabled class, and remove the btn-blue style.Please advise how would a typical test case look like in this case. I have a little knowledge on testing using assert(), but have no idea how to go about it when it involves verifying the result on HTML elements.
Advise how to write a simple test for this javascript snippet?

I appreciate that you do assert()'s. They're simple and powerful, and non-magical. You can test anything that is readable by code. Think if I can if this, then I can assert it. If you want to write a test for something that updates markup, then the question is 'how can I with code get the information I want to test?'. If you're using jQuery (it seems so) then have you test get the button with the selector $('.myButton'). How would you write and if to check the property of this button? I think you can do that. Then use the same code in your assert. You're closer than you think, you can do it!
