Q161.
What is the impact of software failures on society?

a.

Software failures have no impact on society.

b.

Software failures lead to increased dependence on automation.

c.

Software failures pose a threat to society.

d.

Software failures have a positive impact on society.

Discuss
Answer: (c).Software failures pose a threat to society. Explanation:As society's dependence on automation increases, the quality of the systems delivered increasingly determines the quality of our existence. The role of automation in critical applications and the threats these applications pose should make us ponder. The ACM Software Engineering Notes runs a column "Risks to the public in computer systems" in which numerous near accidents caused by software failures are reported.
Q162.
What percentage of software errors are introduced during the design phase according to an early study by Boehm?

a.

40%

b.

60%

c.

70%

d.

80%

Discuss
Answer: (b).60% Explanation:An early study by Boehm showed that over 60% of the errors were introduced during the design phase.
Q163.
When is the best time to start testing activities for software development?

a.

After the design phase

b.

After the implementation stage

c.

As early as possible

d.

After the design specification

Discuss
Answer: (c).As early as possible Explanation:It is best to start testing activities as early as possible to reduce the number of errors. An extreme form of this is test-driven development, in which development starts with writing tests.
Q164.
What can be tested during the software development life cycle?

a.

Only the implementation stage

b.

Requirements specification, design, and design specification

c.

Only the design stage

d.

Only the design specification

Discuss
Answer: (b).Requirements specification, design, and design specification Explanation:The requirements specification, design, and design specification can also be tested during the software development life cycle. The rigor depends on the form in which these documents are expressed.
Q165.
What does testing software show?

a.

The absence of errors

b.

The presence of errors

c.

The exact number of errors

d.

The proper functioning of the software

Discuss
Answer: (b).The presence of errors Explanation:Testing software shows only the presence of errors, not their absence. It yields a negative result, indicating the number of errors found so far.
Q166.
How can we be certain about the proper functioning of software?

a.

By testing it exhaustively

b.

By testing it once

c.

By testing it for a limited number of outcomes

d.

By not testing it

Discuss
Answer: (a).By testing it exhaustively Explanation:Only when the software is tested exhaustively are we certain about its proper functioning. In practice, this seldom happens due to the large number of possible outcomes for even a simple program.
Q167.
What is the objective of coverage-based testing?

a.

To detect faults

b.

To prove the correctness of the software

c.

To execute all statements of the program at least once

d.

To focus on error-prone points

Discuss
Answer: (c).To execute all statements of the program at least once Explanation:Coverage-based testing focuses on executing all statements of the program at least once. The adequacy of the test set is measured in terms of the coverage of the product to be tested.
Q168.
What is the objective of fault-based testing?

a.

To execute all statements of the program at least once

b.

To prove the correctness of the software

c.

To detect faults

d.

To focus on error-prone points

Discuss
Answer: (c).To detect faults Explanation:Fault-based testing focuses on detecting faults. The fault detecting ability of the test set determines its adequacy.
Q169.
What is the objective of error-based testing?

a.

To execute all statements of the program at least once

b.

To prove the correctness of the software

c.

To detect faults

d.

To focus on error-prone points

Discuss
Answer: (d).To focus on error-prone points Explanation:Error-based testing focuses on error-prone points, based on knowledge of the typical errors that people make.
Q170.
What is the objective of black-box testing?

a.

To consider implementation details

b.

To focus on error-prone points

c.

To derive test cases from the specification of the software

d.

To consider the internal logical structure of the software

Discuss
Answer: (c).To derive test cases from the specification of the software Explanation:Black-box testing, also called functional or specification-based testing, focuses on deriving test cases from the specification of the software without considering implementation details.
