See here for example: http://www.johnpapa.net/angularjss-controller-as-and-the-vm-variable/
As the title suggests, I'm following along on this tutorial [http://tech.pro/tutorial/1473/getting-started-with-angularjs-unit-testing] to setup unit testing and all is fine EXCEPT for the fact I can't seem to access the vm variable as my $scope.
dashboard.js
var controllerId = 'dashboard';
angular.module('app')
.controller(controllerId, ['common', 'datacontext', dashboard]);
function dashboard(common, datacontext) {
var getLogFn = common.logger.getLogFn;
var log = getLogFn(controllerId);
var vm = this;
vm.title = 'Dashboard';
dashboard.Spec.js
describe("app module", function() {
beforeEach(module("app"));
describe("dashboard", function() {
var scope,
controller;
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new();
controller = $controller;
}));
it("should assign Dashboard as title", function() {
controller("dashboard", {
$scope: scope
});
expect(scope.title).toBe("Dashboard");
});
});
});
What I've tried: it works (the test passes) when I name '$scope' directly in the controllers dependencies and set the "title" property to it. However, I'd like to keep the pattern as is.
I've also tried passing in $scope directly in dependencies and naming the controller parameter as "vm"...
Karmas failing test message is: Expected undefined to be 'Dashboard'
appreciate any help!
Ah, obvious now...I can access the vm variable through making a reference to the controller that's created in the test:
it("should assign Dashboard as title", function () {
var vm = controller("dashboard", { $scope: scope });
expect(vm.title).toBe("Dashboard");
});
