How to check the properties set in the controller. $ OnInit method in angular js

Question

I have a scenario in which I initialize some of the variables in the controller. Method $ onInit. How to check if these properties are set correctly?

controller

 ctrl.$onInit = function () {
    ctrl.devices = _.cloneDeep(ctrl.formDevices);
};

Unit test

it('should expose device related properties to view', function () {
        expect(controller.devices).toBeDefined();
};

Output

Unit test output

it('should expose device related properties to view', function () {
    controller.$onInit();
    expect(controller.devices).toBeDefined();
};
