Class VisibilityEventsHelper

java.lang.Object

com.facebook.litho.testing.helper.VisibilityEventsHelper

public class VisibilityEventsHelper
extends java.lang.Object

Allows calling visibility events manually which is useful in automated tests

Since this requires a bunch of private APIs, and we haven't reached a conclusion of whether they should be public we are making aggressive use of reflection through Whitebox to call them
