Analyse the following highly simplified procedure:
Ask:What type of ticket do you require, single or return?"
IF the customer wants 'return'
Ask:What rate, Standard or Cheap-day?"
IF the customer replies 'Cheap-day'
Say:That will be £11:20"
ELSE
Say:That will be £19:50"
ENDIF
ELSE
Say:That will be £9:75"
ENDIF
Now decide the minimum number of tests that are needed to ensure that all the
questions have been asked, all combinations have occurred and all replies given.
a)3
b)4
c)5
d)6 - Correct Answers -A

Which of the following is NOT true of test coverage criteria?
a)Test coverage criteria can be measured in terms of items exercised by a test suite.
b)A measure of test coverage criteria is the percentage of user requirements covered.
c)A measure of test coverage criteria is the percentage of faults found.
d)Test coverage criteria are often used when specifying test completion criteria. -
