incremental testing
subject			fact

incremental testing	has definition A integration testing strategy in which you test subsystems in isolation, and then continue testing as you integrate more and more subsystems
	is a subtopic of 10.9 - Strategies for Testing Large Systems
	is a kind of integration testing
integration testing	has advantage when you find a problem, you can find the defect more easily because you have a better idea in which subsystem to look
	is better than big bang testing for large systems
testing	can find defects whose consequences are obvious but which are buried in complex code, and thus will be hard to detect when inspecting
	involves thinking of what could go wrong without actually studying the software
	requires attention to detail
process	see also process^2
