integration testing
subject			fact

integration testing	has definition Testing a system in a phased approach - first testing individual subsystems, then testing the integrated system
	has definition Testing during or following the process of integrating a system
	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
	is a subtopic of 10.9 - Strategies for Testing Large Systems
	is a kind of testing performed by software engineers
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

Kinds of integration testing :

• big bang testing (5 facts) - An inappropriate approach to integration testing in which you take the entire integrated system and test it as a unit
• incremental testing (2 kinds, 3 facts) - A integration testing strategy in which you test subsystems in isolation, and then continue testing as you integrate more and more subsystems
