Q171.
What is the objective of white-box testing?

a.

To derive test cases from the specification of the software

b.

To focus on error-prone points

c.

To consider the internal logical structure of the software in the derivation of test cases

d.

To consider implementation details

Discuss
Answer: (c).To consider the internal logical structure of the software in the derivation of test cases Explanation:White-box testing, also called structural or program-based testing, focuses on considering the internal logical structure of the software in the derivation of test cases.
Q172.
What is the main objective of testing software?

a.

To find as many errors as possible

b.

To increase confidence in the proper functioning of the software

c.

To prove the correctness of the software

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:The objective of testing software can either be to find as many errors as possible, or to increase confidence in the proper functioning of the software. It depends on the objective set forth.
Q173.
What is the main drawback of proving the correctness of software?

a.

It only applies to formal requirements

b.

It becomes a tiresome activity

c.

It cannot determine the correctness of formal requirements

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Proving the correctness of software is a tiresome activity that only applies to circumstances where software requirements are stated formally. Furthermore, it cannot determine the correctness of formal requirements.
Q174.
What is the difference between black-box testing and white-box testing?

a.

Black-box testing is based on the specification, while white-box testing is based on the internal structure of the software

b.

White-box testing is based on the specification, while black-box testing is based on the internal structure of the software

c.

Black-box testing and white-box testing are the same thing

d.

None of the above

Discuss
Answer: (a).Black-box testing is based on the specification, while white-box testing is based on the internal structure of the software Explanation:Black-box testing, also called functional or specification-based testing, derives test cases from the specification of the software without considering implementation details. On the other hand, white-box testing, also called structural or program-based testing, considers the internal logical structure of the software in the derivation of test cases.
Q175.
What is the main goal of system level testing?

a.

Detecting faults

b.

Building trust

c.

Quantitatively assessing reliability

d.

Both b and c

Discuss
Answer: (d).Both b and c Explanation:The main goal of system level testing is to build trust and quantitatively assess reliability.
Q176.
What is an error?

a.

A human action that produces a correct result

b.

A software containing a fault

c.

A manifestation of a fault

d.

A failure

Discuss
Answer: (a).A human action that produces a correct result Explanation:An error is a human action that produces an incorrect result. The consequence of an error is software containing a fault.
Q177.
What is a fault?

a.

A human action that produces a correct result

b.

A software containing an error

c.

A manifestation of an error

d.

A failure

Discuss
Answer: (c).A manifestation of an error Explanation:A fault is the manifestation of an error. If encountered, a fault may result in a failure.
Q178.
What is the aim of testing in software?

a.

To find errors in the software

b.

To find faults in the software

c.

To find failures in the software

d.

To find none of the above

Discuss
Answer: (b).To find faults in the software Explanation:The aim of testing in software is to find faults in the software. Tests are then intended to expose failures.
Q179.
What is the relation between errors and faults?

a.

1-1

b.

1-Many

c.

Many-1

d.

None of the above

Discuss
Answer: (d).None of the above Explanation:The relation between errors and faults need not be 1-1. A failure may be caused by more than one fault, and a fault may cause different failures.
Q180.
What is the difference between verification and validation in software?

a.

Verification is to determine whether the software meets the specifications.

b.

Validation is to determine whether the software meets the specifications.

c.

Verification is to determine whether the software is built right.

d.

Validation is to determine whether the software is built right.

Discuss
Answer: (c).Verification is to determine whether the software is built right. Explanation:Verification is the process of evaluating a system to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase. Validation is the process of evaluating a system to determine whether it satisfies specified requirements.
