Q181.
What is the definition of "error" in the context of software testing?

a.

A human action that produces a correct result

b.

A human action that produces an incorrect result

c.

The manifestation of a human action in the form of a fault

d.

The consequence of a software containing a fault

Discuss
Answer: (b).A human action that produces an incorrect result Explanation:An error is defined as a human action that produces an incorrect result.
Q182.
What is the relationship between errors and faults in software testing?

a.

There is a one-to-one relationship between errors and faults

b.

There is no relationship between errors and faults

c.

The relationship between errors and faults is not always one-to-one

d.

There is a one-to-many relationship between errors and faults

Discuss
Answer: (c).The relationship between errors and faults is not always one-to-one Explanation:The relationship between errors and faults need not be one-to-one. A failure may be caused by more than one fault, and a fault may cause different failures.
Q183.
What is the goal of software testing?

a.

To find errors in the software

b.

To expose faults in the software

c.

To find failures in the software

d.

To find faults in the software and expose failures

Discuss
Answer: (d).To find faults in the software and expose failures Explanation:The goal of software testing is to find faults in the software and expose failures. Tests are intended to expose failures, which are caused by faults, which are in turn the result of human errors.
Q184.
What is the difference between "verification" and "validation" in software testing?

a.

Verification determines if the software satisfies specified requirements while validation determines if the system has been built right

b.

Verification determines if the system has been built right while validation determines if the software satisfies specified requirements

c.

Verification and validation are the same thing

d.

There is no difference between verification and validation

Discuss
Answer: (b).Verification determines if the system has been built right while validation determines if the software satisfies specified requirements Explanation:Verification evaluates a system or component to determine if the products of a given development phase satisfy the conditions imposed at the start of that phase, trying to answer the question "Have we built the system right?" Validation, on the other hand, evaluates a system or component during or at the end of the development process to determine if it satisfies specified requirements, trying to answer the question "Have we built the right system?"
Q185.
What is a program considered if it consistently produces the right output?

a.

Faulty

b.

Incorrect

c.

Correct

d.

Latent fault

Discuss
Answer: (c).Correct Explanation:Generally, a program is considered correct if it consistently produces the right output.
Q186.
What is a latent fault in a program?

a.

An error that is consistently producing the right output

b.

An error that is not manifesting itself

c.

An error that is revealed by test cases

d.

An error that is subsumed by a previous entry

Discuss
Answer: (b).An error that is not manifesting itself Explanation:A latent fault in a program is an error that is not manifesting itself, even though the programmer's intention is not properly reflected in the program.
Q187.
How is the expected output of a program determined during the test process?

a.

By comparing the output with the previous program

b.

By using an oracle

c.

By exhaustive testing

d.

By the selection of a subset of the input domain

Discuss
Answer: (b).By using an oracle Explanation:The expected output of a program during the test process is determined by an oracle, something outside the test activity.
Q188.
What is the most crucial step in the testing process?

a.

Deriving the test cases

b.

Comparing the expected output with the corresponding output

c.

Selecting the subset of the input domain

d.

Deciding upon the oracle

Discuss
Answer: (c).Selecting the subset of the input domain Explanation:The most crucial step in the testing process is the selection of the subset of the input domain which will serve as the test set.
Q189.
What is the main objective of the test techniques used in testing?

a.

Fault detection

b.

Failure-free behavior

c.

Fault prevention

d.

Both a and c

Discuss
Answer: (a).Fault detection Explanation:The main objective of the test techniques is fault detection. The test cases are meant to provoke failures.
Q190.
What is the main objective of test techniques?

a.

Fault prevention

b.

Fault detection

c.

Increasing confidence in failure-free behavior

d.

All of the above

Discuss
Answer: (b).Fault detection Explanation:The main objective of test techniques is to provoke failures and detect faults.
