Which testing approach is MOST appropriate to ensure that internal application interface errors are identified as soon as possible?
A. Bottom up
B. Sociability testing
C. Top-down
D. System test
Explanation:
The top-down approach to testing ensures that interface errors are detected early and that testing of major functions is conducted early. A bottom-up approach to testing begins with atomic units, such as programs and modules, and works upward until a complete system test has taken place. Sociability testing and system tests take place at a later stage in the development process.
