angularjs - testing controller - unit-testing

Question

I am just starting with angular and I wanted to write some simple unit tests for my controllers, here is what I got.
app.js:
'use strict';
// Declare app level module which depends on filters, and services
angular.module('Prototype', ['setsAndCollectionsService']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/dashboard', {templateUrl: 'partials/dashboard.html', controller: 'DashboardController'});
$routeProvider.when('/setsAndCollections', {templateUrl: 'partials/setsAndCollections.html', controller: SetsAndCollectionsController});
$routeProvider.when('/repetition', {templateUrl: 'partials/repetition.html', controller: RepetitionController});
$routeProvider.otherwise({redirectTo: '/dashboard'});
}]);
and controllers.js
'use strict';
/* Controllers */
var myApp = angular.module('Prototype');
myApp.controller('DashboardController', ['$scope', function (scope) {
scope.repeats = 6;
}]);
/*function DashboardController($scope) {
$scope.repeats = 5;
};*/
function SetsAndCollectionsController($scope, $location, collectionsService, repetitionService) {
$scope.id = 3;
$scope.collections = collectionsService.getCollections();
$scope.selectedCollection;
$scope.repetitionService = repetitionService;
$scope.switchCollection = function (collection) {
$scope.selectedCollection = collection;
};
$scope.addCollection = function () {
$scope.collections.push({
name: "collection" + $scope.id,
sets: []
});
++($scope.id);
};
$scope.addSet = function () {
$scope.selectedCollection.sets.push({
name: "set" + $scope.id,
questions: []
});
++($scope.id);
};
$scope.modifyRepetition = function (set) {
if (set.isSelected) {
$scope.repetitionService.removeSet(set);
} else {
$scope.repetitionService.addSet(set);
}
set.isSelected = !set.isSelected;
};
$scope.selectAllSets = function () {
var selectedCollectionSets = $scope.selectedCollection.sets;
for (var set in selectedCollectionSets) {
if (selectedCollectionSets[set].isSelected == false) {
$scope.repetitionService.addSet(set);
}
selectedCollectionSets[set].isSelected = true;
}
};
$scope.deselectAllSets = function () {
var selectedCollectionSets = $scope.selectedCollection.sets;
for (var set in selectedCollectionSets) {
if (selectedCollectionSets[set].isSelected) {
$scope.repetitionService.removeSet(set);
}
selectedCollectionSets[set].isSelected = false;
}
};
$scope.startRepetition = function () {
$location.path("/repetition");
};
}
function RepetitionController($scope, $location, repetitionService) {
$scope.sets = repetitionService.getSets();
$scope.questionsLeft = $scope.sets.length;
$scope.questionsAnswered = 0;
$scope.percentageLeft = ($scope.questionsLeft == 0 ? 100 : 0);
$scope.endRepetition = function () {
$location.path("/setsAndCollections");
};
}
now I am in process of converting global function controllers to ones defined by angular API as you can see by example of DashboardController.
Now in my test:
describe("DashboardController", function () {
var ctrl, scope;
beforeEach(inject(function ($rootScope, $controller) {
scope = $rootScope.$new();
ctrl = $controller('DashboardController', {$scope: scope});
}));
it("has repeats attribute set to 5", function () {
expect(scope.repeats).toBe(5);
});
});
I am getting
Error: Argument 'DashboardController' is not a function, got undefined
I am wondering then, where is my mistake? If I understand this right, ctrl = $controller('DashboardController', {$scope: scope}); should inject my newly created scope to my DashboardController to populate it with attributes - in this case, repeats.

You need to set up your Prototype module first.
beforeEach(module('Prototype'));
Add that to your test, above the current beforeEach would work.
describe("DashboardController", function () {
var ctrl, scope;
beforeEach(module('Prototype'));
beforeEach(inject(function ($rootScope, $controller) {
scope = $rootScope.$new();
ctrl = $controller('DashboardController', {$scope: scope});
}));
it("has repeats attribute set to 5", function () {
expect(scope.repeats).toBe(5);
});
});
