Get instance of directive controller with Angular/Jasmine - angularjs

Question

When unit testing angular directives, how can I grab an instance of the directive controller and assert certain data bindings on the controller?
function myDirective() {
return {
restrict: 'E',
replace: true,
templateUrl: 'tpl.html',
scope: { },
controller: function($scope) {
$scope.text = 'Some text';
}
};
}
angular
.module('example')
.directive('myDirective', [
myDirective
]);
unit test
describe('<my-directive>', function() {
var element;
var $compile;
var $scope;
beforeEach(module('example'));
beforeEach(function() {
inject(function(_$compile_, _$rootScope_) {
$compile = _$compile_;
$scope = _$rootScope_.$new();
});
});
describe('basic functionality', function() {
beforeEach(function() {
element = $compile('<my-directive></my-directive')($scope);
$scope.$digest();
});
it('should bind the correct text', function() {
//?
});
});
});

Answer 1

element = $compile('<my-directive></my-directive')($scope);
$scope.$digest();
ctrl = element.controller('myDirective');

Answer 2

Call element.controller with $scope like element.controller($scope). Some proof of concept bellow.
angular
.module('example', [])
.directive('myDirective', [
function myDirective() {
return {
restrict: 'E',
replace: true,
//template: ['<div>{{ text }}</div>'].join(''),
scope: {},
controller: function($scope) {
$scope.text = 'Some text';
}
};
}
]);
describe('<my-directive>', function() {
var element;
var $compile;
var $scope;
beforeEach(module('example'));
beforeEach(function() {
inject(function(_$compile_, _$rootScope_) {
$compile = _$compile_;
$scope = _$rootScope_.$new();
});
});
describe('basic functionality', function() {
beforeEach(function() {
element = $compile('<my-directive></my-directive')($scope);
$scope.$digest();
});
it('should bind the correct text', function() {
expect(element.controller($scope).scope().$$childTail.text).toEqual('Some text')
});
});
});
