// Creates a dummy Page, LocalFrame, and LocalFrameView whose clients are all

//
// This class can be used when you write unit tests for components which do not
// work correctly without layoutObjects.  To make sure the layoutObjects are
// created, you need to call |frameView().layout()| after you add nodes into
// |document()|.
//
// Since DummyPageHolder stores empty clients in it, it must outlive the Page,
// LocalFrame, LocalFrameView and any other objects created by it.
// DummyPageHolder's destructor ensures this condition by checking remaining
// references to the LocalFrame.
