Jasmine cannot read property of undefined
<p>I usually don't post the whole stack trace, but I've been having this problem with one individual unit test and it's driving me nuts.  I've rewritten it at least 10 different times and 20 different ways, and I keep getting the same error.</p>

<pre><code>TypeError: Cannot read property 'allAccountRangeFlag' of undefined

<p>I am unit testing an Angular directive.  The directive has a controller, which has functions, which use global variables.  <code>allAccountRangeFlag</code> is one of those variables.</p>

<p>This is a snippet of the directive that is being tested:</p>

<pre><code>app.directive('shuffleBox', function() {
    var controller = ['$scope', '$filter', function($scope, $filter) {
        $scope.disableAddButton = function() {
             if(!$scope.args.allAccountRangeFlag) {
                  // do stuff with filtered data and $filter
             }
         };
    }];

    return {
         ...,
         controller: controller,        
         ...
    };
});
</code></pre>

<p>And the test itself, in its simplest form:</p>

<pre><code>describe('shuffleBox directive', function() {
    var $compile,
        $rootScope,
        shuffleBoxargs = { 
             availableValues : [],
             key : 'id',
             selectedValues : [],
             searchText : '',
             allAccountRangeFlag : false
         };

    beforeEach(module('app'));
    beforeEach(module('path/to/shuffleBox.html'));

    beforeEach(inject(function(_$compile_, _$rootScope_) {
        $compile = _$compile_;
        $rootScope = _$rootScope_;
    }));

    it('should compile', function() {
        var element = $compile('&lt;div shuffle-box args="shuffleBoxargs"&gt;&lt;/div&gt;')($rootScope);
        $rootScope.$digest();
        expect(element.html()).not.toBeNull();
    });
});
</code></pre>

<p><strong>UPDATE</strong>: I wasn't injecting enough "stuff" in the <code>beforeEach</code> block:</p>

<pre><code>describe('shuffleBox', function() {      

    beforeEach(module('app'));
    beforeEach(module('scripts/components/directives/shuffleBox/shuffleBox.html'));

    //properties to hold shuffleBox selections
    var shuffleBoxargs = { 
        availableValues : [],
        key : 'id',
        selectedValues : [],
        searchText : '',
        allAccountRangeFlag : false
    };  

    beforeEach(inject(function($templateCache, _$compile_, _$rootScope_, _$filter_) {
        template = $templateCache.get('main/webapp/scripts/components/directives/shuffleBox/shuffleBox.html');
        $templateCache.put('main/webapp/scripts/components/directives/shuffleBox/shuffleBox.html', template);
        $compile = _$compile_;
        $rootScope = _$rootScope_;
        $filter = _$filter_;

        var sbElement = angular.element('&lt;div shuffle-box args="shuffleBoxargs" &gt;&lt;/div&gt;');
        var element = $compile(sbElement)($rootScope);
        scope = element.isolateScope() || element.scope();  
        scope.args = shuffleBoxargs;

        // Grab controller instance
        controller = element.controller("shuffleController");
        $rootScope.$digest();
    }));



    it('shuffle-box directive', function() {
        expect(scope.disableAddAllButton()).toBeDefined();    
    });    
});
</code></pre>

<p>However, now I am getting a new error:</p>
