A top-down development strategy affects which level of testing most?
A . Component testing
B . Integration testing
C . System testing
D . User acceptance testing

Answer: B

Explanation:

The development strategy will affect the component testing (option (A)), in so far as it cannot be tested unless it has been built. Options (C) and (D) require the system to have been delivered; at these points the development strategy followed is not important to the tester. Option (B) needs knowledge of the development strategy in order to determine the order in which components will be integrated and tested.
