Javascript Unit Testing

The following posts will use QUnit functions for testing. There is no explicit marking of QUnit functoins. So, when in doubt search in QUnit API.

Testing if a button was clicked

The following code shows you how to unit test weather a button was clicked in javascript. I found need for this while trying to test the following scenario: When user presses enter while an input box has focus then fire a click event on the button next to the input box.

test(“button clicked”, function(){
 $(“#button”).on(‘click’, function(event){
  $(this).data(‘clicked’, true);
});

$(“#button”).click();
        ok($(“#button”).data(‘clicked’), “button clicked”)
});

As you can see the sky is the limit to what can be tested with such a technique.
