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 ...
