b. Checks the final product against the specification.
c. Usually carried out by the test team.
d. Checks whether an artifact produced in a phase conforms to the corresponding artifact produced in a previous phase.

c. After a test methodology has been used to detect bugs, it becomes ineffective for detecting the remaining bugs

Answer 1

1. c

2.d

3.d

4.d

5.a

6.c

7.d

8.d

Answer 2

1. C is the correct option that is every failure is caused by a fault.

2. D is the correct option about verification that is checks whether an artifact produced in a phase conforms to the corresponding artifact produced in a previous phase.

3. C is the correct answer for the pesticide paradox that is after a test methodology has been used to detect bugs.

4. D is the correct answer that is users are considered as entity classes.

5. CRC cards are usually not much useful in performing method identification. Therefore, option A is the correct one.

6. The tester can easily reproduce any failures(c) which are not true of monkey testing.

7. The test team conducts acceptance testing which is option (b).

8. Among the given examples of negative test case option d is the correct answer that is a test case with values outside the valid range of values.
