• b) the process of establishing confidence that a program does what it is supposed to do

• c) the process of executing a program to show it is working as per specifications

• c) Usually carried out by the test team

• d) Checks whether an artifact produced in a phase confirms to the corresponding artifacts produced in a previous phase

6. Why is it necessary to test a large program at three different levels: unit, integration, as well as system levels, rather than testing only at the system level?

• b) Different equivalence classes of a program contain similar bugs

• c) Different equivalence classes of a program contain dissimilar bugs

• d) Equivalence classes define the behaviorally similar components of a program
