Improve this Doc View Source $componentController

  1. service in module ngMock

A service that can be used to create instances of component controllers. Useful for unit-testing.

Be aware that the controller will be instantiated and attached to the scope as specified in the component definition object. If you do not provide a $scope object in the locals param then the helper will create a new isolated scope as a child of $rootScope.

If you are using $element or $attrs in the controller, make sure to provide them as locals. The $element must be a jqLite-wrapped DOM element, and $attrs should be an object that has all properties / functions that you are using in the controller. If this is getting too complex, you should compile the component instead and access the component's controller via the controller function.

See also the section on unit-testing component controllers in the guide.
