Q321.
What is the result of transforming requirements specifications into a graph model?

a.

A graph model of program code

b.

A graph model of elementary requirements and relations between them

c.

A set of test cases based on control-flow coverage criteria

d.

A partition of the program domain into a small number of equivalence classes

Discuss
Answer: (b).A graph model of elementary requirements and relations between them Explanation:The result of transforming requirements specifications into a graph model is a graph model of elementary requirements and relations between them, which allows for the use of control-flow coverage criteria to assess the adequacy of test cases.
Q322.
What is the format used in rewording a use case in requirements specifications?

a.

The format from (Cockburn, 2001)

b.

The format from (Bach, 1999)

c.

The format from (Myers, 1979)

d.

The format from (Kaner, 2002)

Discuss
Answer: (a).The format from (Cockburn, 2001) Explanation:The format used in rewording a use case in requirements specifications is the format from (Cockburn, 2001).
Q323.
What is the weak point in the procedure of determining a set of test cases using control-flow coverage criteria?

a.

The underlying assumption that the program behaves equivalently on all data from a given class

b.

The use of control-flow coverage criteria to assess the adequacy of test cases

c.

The assumption that any test of some node or branch is as good as any other such test

d.

The transformation of requirements specifications into a graph model

Discuss
Answer: (a).The underlying assumption that the program behaves equivalently on all data from a given class Explanation:The weak point in the procedure of determining a set of test cases using control-flow coverage criteria is the underlying assumption that the program behaves equivalently on all data from a given class, which may not hold in general.
Q324.
What is the main idea behind fault-based test techniques?

a.

To consider the structure of the problem or solution being tested

b.

To assess the test adequacy by taking into account the test set

c.

To find a test set with a high ability to detect faults

d.

To estimate the number of faults in the program by seeding them artificially

Discuss
Answer: (c).To find a test set with a high ability to detect faults Explanation:In fault-based testing strategies, the main focus is not on the structure of the problem or solution being tested, but rather on finding a test set with a high ability to detect faults.
Q325.
What is the error seeding technique in fault-based testing strategies?

a.

A technique to estimate the number of pikes in a lake

b.

A technique to artificially seed a number of faults in the program

c.

A technique to determine which faults to seed in the program by hand

d.

A technique to assume that real and seeded faults have the same distribution

Discuss
Answer: (b).A technique to artificially seed a number of faults in the program Explanation:Error seeding is a technique in fault-based testing strategies where a number of faults are artificially seeded into the program, and the test set is used to detect these faults and estimate the total number of faults present in the program.
Q326.
What is the main goal of fault-based testing techniques?

a.

To consider the structure of the problem or its solution

b.

To find a test set with a high ability to detect faults

c.

To estimate the number of faults in a program by seeding them

d.

To construct faults by hand

Discuss
Answer: (b).To find a test set with a high ability to detect faults Explanation:The main goal of fault-based testing techniques is to find a test set with a high ability to detect faults. The test adequacy is not considered based on the structure of the problem or its solution.
Q327.
What is the main advantage of error seeding?

a.

It allows to estimate the number of faults in a program

b.

It provides a fair chance to discover both seeded faults and new faults

c.

It ensures that both real and seeded faults have the same distribution

d.

It provides realistic faults by constructing them by hand

Discuss
Answer: (a).It allows to estimate the number of faults in a program Explanation:The main advantage of error seeding is that it allows to estimate the number of faults in a program by comparing the ratio of seeded faults and the newly discovered faults.
Q328.
What is the purpose of marking the pikes in the example of error seeding in Lake Soft and Lake Seed?

a.

To throw the pikes into Lake Soft

b.

To estimate the number of pikes in Lake Soft

c.

To find the total number of faults in a program

d.

To have a fair chance of discovering both seeded faults and new faults

Discuss
Answer: (b).To estimate the number of pikes in Lake Soft Explanation:The purpose of marking the pikes in the example of error seeding is to estimate the number of pikes in Lake Soft by comparing the ratio of marked pikes and the newly caught pikes.
Q329.
What is the limitation of constructing faults by hand in error seeding?

a.

It provides realistic faults

b.

It ensures that both real and seeded faults have the same distribution

c.

It is unlikely to construct very realistic faults

d.

It allows to estimate the number of faults in a program

Discuss
Answer: (c).It is unlikely to construct very realistic faults Explanation:The limitation of constructing faults by hand in error seeding is that it is unlikely to construct very realistic faults. The faults thought up by one person may have already been thought up by the person who wrote the software.
Q330.
What is error seeding?

a.

A technique for estimating the number of faults in a program

b.

A technique for independently testing a program

c.

A technique for finding the number of pikes in a lake

d.

A technique for constructing faults in a program

Discuss
Answer: (a).A technique for estimating the number of faults in a program Explanation:Error seeding is a fault-based testing technique used to estimate the number of faults in a program by artificially seeding a number of faults in the program and testing it.
