Subject	have procedure	have disadvantage	has definition	find	is a kind of
vertical incremental testing				defects whose consequences are obvious but which are buried in complex code, and thus will be hard to detect when inspecting	incremental testing
top-down testing	test only the user interface, with the underlying functionality simulated by stubs work downwards, integrating lower and lower layers, each time creating stubs for the layers that remain un-integrated as you integrate each lower layer, test the system again	the cost of writing the stubs	An incremental testing strategy in which you start by testing only the user interface, with the underlying functionality simulated by stubs, then you work downwards, integrating lower and lower layers	defects in the layer that was most recently integrated	vertical incremental testing
