Steps to incorporate the controller directive specified within a closure into the testing specification

I followed the recommendation in option 2 of the accepted answer to a question on stackoverflow about unit testing directive controllers in Angular without making the controller global. You can find the original post here.

Here is a snippet of my code:

(function () {

    function myCtrl($scope) {
        //All my controller code.
    };

    myAppModule.directive('myDirective', function($compile, $timeout) {

        return {

            restrict: 'E',

            replace: true,

            controller: myCtrl,

            compile: function(tElement, tAttrs, transclude) {

                return {
                post: function(scope, element, attrs) {
                    //more code and stuff.
                }
            }
        }
    });
})();

I have a simple question; since the controller is not defined within the scope of the module, how can I load it in my test file?

Answer №1

To properly organize the code snippet above, it should be divided into three separate files:

  • Start with all code before function myCtrl($scope) {
  • Controller code section
  • End with the remaining code in a separate file

When developing your application, combine these three files into one to use as the final code.

During testing, include only the controller code file. This prevents global namespace conflicts in tests but is avoided in the productive code using closures.
