isolateScope() returns undefined when using templateUrl

Question

I have a directive that I want to unittest, but I\'m running into the issue that I can\'t access my isolated scope. Here\'s the directive:

&l         


        

Answer 1

I had to mock and flush the $httpBackend before isolateScope() became defined. Note that $scope.$digest() made no difference.

Directive:

app.directive('deliverableList', function () {
    return {
        templateUrl: 'app/directives/deliverable-list-directive.tpl.html',
        controller: 'deliverableListDirectiveController',
        restrict = 'E',
        scope = {
            deliverables: '=',
            label: '@'
        }
    }
})

test:

it('should be defined', inject(function ($rootScope, $compile, $httpBackend) {
    var scope = $rootScope.$new();

    $httpBackend.expectGET('app/directives/deliverable-list-directive.tpl.html').respond();

    var $element = $compile('')(scope);

    $httpBackend.flush();
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();

    expect($element).toBeDefined();
    expect($element.controller).toBeDefined();

    scope = $element.isolateScope();
    expect(scope).toBeDefined();
    expect(scope.label).toEqual('test');
    expect(scope.deliverables instanceof Array).toEqual(true);
    expect(scope.deliverables.length).toEqual(1);
    expect(scope.deliverables[0]).toEqual({id: 123});
}));

I'm using Angular 1.3.
