Explanation / Answer

Sol: 15) Top down integration testing : Top-down integration testing is an integration testing technique used in order to simulate the behaviour of the lower-level modules that are not yet integrated. Stubs are the modules that act as temporary replacement for a called module and give the same output as that of the actual product.

Advantages of top down integration testing :

Isolation of interface errors becomes easier because of incremental nature of top down integration.

Test cases designed to test the integration of a module are reused during the regression tests performed after integrating other modules.

Advantageous if major flaws occur toward the top of the program.

It provides early working module of the program and so design defects can be found and corrected early.
