Interview Question : What is the difference between black box and white box testing?
Answer : Using both black and white box testing techniques, the tester (still usually the software developer) verifies that units work together when they are integrated into a larger code base. Just because the components work individually, that doesn�t mean that they all work together whenassembled or integrated. For example, data might get lost across an interface, messages might not get passed properly, or interfaces might not be implemented as specified. To plan these integration test cases, testers look at high- and low-level design documents.
