for application P what might be the possible explanations for the

lack of coverage of method 9 by tests in T



?

5.29 In what ways does a call graph differ from the DDG based on

function trace ?

5.30 Let T be a set of non-obsolete tests for P. Let P



be obtained by

modifying P. Regression testing of P



is done using a subset T



of

tests in T. What is the advantage of applying coverage-based test

minimization procedure as in Section 5.8 to (a) T



and (b) T?

5.31 Let T be a test suite for testing P and T



a minimized test suite for

testing the modified version P



of P. Give reasons why the

fault-detection effectiveness of T



might be less than that of T.

Construct an example to show that indeed there exist cases where

a fault in P



is detected by a test case ...
