Sets the checked attribute on the element, if the expression inside ngChecked is truthy.

Note that this directive should not be used together with ngModel, as this can lead to unexpected behavior.

A special directive is necessary because we cannot use interpolation inside the checked attribute. See the interpolation guide for more info.

it('should check both checkBoxes', function() {
