ng-mocks & ViewChild

[LukasMachetanz]

Hey!

I am curious how ng-mocks ensures the correct behavior in combination with ViewChild; e.g. using it like ViewChild(MyCompoment) having MyComponent mocked with MockComponent. This article describes the problem with the usual naive approach very well. Does ng-mocks use the described solution or is an alternative approach used?

Thanks. Greets,
Lukas

Hi there,

I think we could extend this documentation: https://ng-mocks.sudo.eu/guides/view-child

Feel free to let me know what is missing there.

Hey, the documentation is perfectly fine for using it. I am more interested in the actual implementation and the approach how this works behind the scenes. :)

There is nothing special. ng-mocks adds to providers info that a mock should be used when its real class is requested, the rest is done by angular.
