How to inject controller dependencies in Jasmine tests? - angularjs

Question

There is the following controller definition:
angular.module('app.controllers', []).controller('HomeController', [
'$scope', '$modal', 'Point', function($scope, $modal, Point) { //some action }
I want to test this controller:
describe('HomeController', function() {
beforeEach(module('app.controllers'));
var $controller;
beforeEach(inject(function(_$controller_){
// The injector unwraps the underscores (_) from around the parameter names when matching
$controller = _$controller_;
}));
describe('$scope.grade', function() {
it('sets the strength to "strong" if the password length is >8 chars', function() {
var $scope = {};
var controller = $controller('HomeController', { $scope: $scope });
$scope.label = '12345';
$scope.addNewPoint();
expect($scope.label).toEqual(null);
});
});
});
"Point" is my custom service, "$modal" is Angular Bootstrap module. How can I inject it in my tests? Thanks in advance!

The services should be automatically injected. If you wish to mock them or spy on them, inject them like so:
describe('HomeController', function() {
beforeEach(module('app'));
var $controller, $scope, $modal, Point;
beforeEach(inject(function(_$controller_, _$rootScope_, _$modal_, _Point_){
$scope = $rootScope.$new();
$modal = _$modal_;
Point = _Point_;
spyOn($modal, 'method');
spyOn(Point, 'method');
$controller = _$controller_('HomeController', { $scope: $scope, $modal: $modal, Point: Point });
}));
describe('$scope.grade', function() {
it('sets the strength to "strong" if the password length is >8 chars', function() {
$scope.label = '12345';
$scope.addNewPoint();
expect($scope.label).toEqual(null);
});
});
});
