Angularjs and qunit testing - angularjs

Question

I have a angularjs web application and want to use qunit for unit testing in it. I have a controller:
function RootCtrl($scope, $rootScope, $window, $location) {
// logger is empty at the start
$scope.logger = '';
// we have no login error at the start
$scope.login_error = '';
//
// Get values array of object
//
$rootScope.values = function (obj) {
var vals = [];
for( var key in obj ) {
if(key !== '$$hashKey' && key !== 'checked')
vals.push(obj[key]);
}
return vals;
}
}
Now i want to write unit test for values function with qunit. I included all js files to the test/index.html and qunit.css. Now my test.js has following content:
var injector = angular.injector(['ng', 'myApp']);
var init = {
setup : function () {
this.$scope = injector.get('$rootScope').$new();
}
}
module('RootCtrl', init);
test('RootCtrl', function(){
var $controller = injector.get('$controller');
$controller('RootCtrl', {
$scope : this.$scope,
$location : this.$location
});
equal(['value'], $controller.values({'key' : 'value'}))
});
But i'm getting error: http://docs.angularjs.org/error/$injector/unpr?p0=$rootElementProvider%20%3C-%20$rootElement%20%3C-%20$location%20%3C-%20$route at:
$controller('RootCtrl', {
$scope : this.$scope,
$location : this.$location
});
How to inject correctly controller and use $scope, $rootScope, $location and another services from it?
Thank you.

Answer 1

Try this instead of your controller
$controller('RootCtrl',['$scope', '$rootScope', '$location','$route', function ($scope, $rootScope, $location, $route) {
$scope : this.$scope,
$location : this.$location
}]);

Had similar problem, so since no other answer here.
I ended up using:
client side code:
var myApp= angular.module('myApp', []);
myApp.controller('myCtrl', function ($scope) {
//angular client side code
$scope.canSubmit = function () {
//some logic
return true;
}
}
Qunit tests:
var ctrl, ctrlScope, injector;
module("Testing the controller", {
setup: function () {
angular.module('myApp');
injector = angular.injector(['ng', 'myApp']);
ctrlScope = injector.get('$rootScope').$new();
ctrl = injector.get('$controller')('myCtrl', { $scope: ctrlScope });
ctrlScope.model = {
//model object
};
},
teardown: function () {
}
});
test("Given something happened then allow submit", function () {
ok(ctrlScope.someFunction(...), "some functionality happened");
equal(true, ctrlScope.canSubmit());
});
This blog post was useful.
One can easily inject more into the controller under test.
