Q153.
What is the purpose of testing in software engineering?

a.

To see whether a given input yields the correct output

b.

To locate and fix errors

c.

To plan and document carefully

d.

To trust the software

Discuss
Answer: (a).To see whether a given input yields the correct output Explanation:Testing in software engineering is done to see whether a given input yields the correct output.
Q154.
What is the role of automation in software engineering?

a.

To make our existence better

b.

To hide from responsibility

c.

To cause numerous accidents

d.

To increase the quality of systems

Discuss
Answer: (d).To increase the quality of systems Explanation:As our society's dependence on automation ever increases, the quality of the systems we deliver increasingly determines the quality of our existence.
Q155.
What are the difficulties in answering questions related to the trust in automated systems?

a.

The hardware of an airplane is as complex as the software for an automatic pilot

b.

Automated systems do not pose a threat

c.

It is easy to answer the questions in the affirmative

d.

Software reliability is not a concern

Discuss
Answer: (a).The hardware of an airplane is as complex as the software for an automatic pilot Explanation:The hardware of an airplane probably is as complex as the software for an automatic pilot, but most people board airplanes without second thoughts.
Q156.
What is the goal of software engineers?

a.

To locate and fix errors

b.

To attain the perfect solution

c.

To hide from responsibility

d.

To make software unreliable

Discuss
Answer: (b).To attain the perfect solution Explanation:Engineers aim for the perfect solution but know that it is generally unattainable.
Q157.
Is good testing as difficult as good design in software engineering?

a.

No, testing is easier than design

b.

It depends on the complexity of the software

c.

Yes, good testing is at least as difficult as good design

d.

Testing is not important in software engineering

Discuss
Answer: (c).Yes, good testing is at least as difficult as good design Explanation:Good testing is at least as difficult as good design, as it is a laborious affair to locate and fix errors through excessive testing and not all the errors are found.
Q158.
What is the significance of testing in software development projects?

a.

Testing is a routine activity that is often taken for granted.

b.

Testing is an important aspect of software development that cannot be ignored.

c.

Testing is a costly affair that is often postponed until the end of a project.

d.

Testing is not required for small and noncritical systems.

Discuss
Answer: (b).Testing is an important aspect of software development that cannot be ignored. Explanation:Testing is an important aspect of software development and cannot be ignored as it is critical to the quality of the systems delivered and determines the quality of our existence. Postponing test activities is considered to be a severe mistake and errors discovered later in the software development process incur higher costs compared to those discovered in the early stages.
Q159.
What is the cost of error correction for errors discovered after the software has become operational?

a.

1 to 5 times higher than the cost of errors discovered during the design phase.

b.

10 to 90 times higher than the cost of errors discovered during the design phase.

c.

Equal to the cost of errors discovered during the design phase.

d.

The cost cannot be determined as it depends on the size and criticality of the system.

Discuss
Answer: (b).10 to 90 times higher than the cost of errors discovered during the design phase. Explanation:According to the study by Boehm, the cost of error correction for errors discovered after the software has become operational is 10 to 90 times higher than the cost of errors discovered during the design phase. The ratio still holds for big and critical systems.
Q160.
How many errors are estimated to be present per 1000 lines of source code in software?

a.

0.5-3 errors per 1000 lines of code

b.

5-10 errors per 1000 lines of code

c.

15-30 errors per 1000 lines of code

d.

30-85 errors per 1000 lines of code

Discuss
Answer: (d).30-85 errors per 1000 lines of code Explanation:Different studies indicate that 30-85 errors per 1000 lines of source code are made in software. These figures seem to not improve over time.
