Class ViewTreeAssert

java.lang.Object

<any>

com.facebook.litho.testing.viewtree.ViewTreeAssert

public final class ViewTreeAssert
extends <any>

Assertions which require checking an entire view tree

NOTE: Assertions looking for visible attributes are limited to checking the visibility of the nodes, but do not check actual layout. So a visible view might have 0 pixels available for it in actual app code and still pass the checks done here
