Q331.

What is the assumption underlying the error seeding technique?

That both real and seeded faults have the same distribution

That the program will be independently tested by two groups

That the faults found by the first group will be considered seeded faults for the second group

That faults thought up by one person will not have been thought up by the person who wrote the software

Discuss

Answer: (a).That both real and seeded faults have the same distribution Explanation:One of the assumptions underlying the error seeding technique is that both real and seeded faults have the same distribution.

Q332.

What is a not very satisfactory technique for determining which faults to seed in the program?

Having the program independently tested by two groups

Constructing the faults by hand

Finding a strong linear relationship between the number of defects

Observing many seeded faults and relatively few others

Discuss

Answer: (b).Constructing the faults by hand Explanation:One technique for determining which faults to seed in the program is to construct them by hand, but this is considered to be not very satisfactory as it is unlikely that very realistic faults can be constructed in this way.

Q333.

What is a useful rule of thumb for the technique of having the program independently tested by two groups?

If many seeded faults and relatively few others are found, the result can be trusted

If during testing of a certain component, many faults are found, it is a positive sign

If a strong linear relationship is found between the number of defects, the result can be trusted

If the faults found by the first group are considered seeded faults for the second group, the result can be trusted

Discuss

Answer: (a).If many seeded faults and relatively few others are found, the result can be trusted Explanation:A useful rule of thumb for the technique of having the program independently tested by two groups is that if many seeded faults and relatively few others are found, the result can be trusted.

Q334.

What is the relationship between the number of defects discovered during early phases of development and the number of defects discovered later?

A positive relationship

A negative relationship

A strong linear relationship

No relationship

Discuss

Answer: (c).A strong linear relationship Explanation:A strong linear relationship has been observed between the number of defects discovered during early phases of development and the number of defects discovered later. This means that the number of defects found early on is directly proportional to the number of defects found later on.

Q335.

What is the purpose of mutation testing?

To find the correct results of a program

To generate variants of a program and test their results

To evaluate the quality of a test set

To determine the number of live mutants

Discuss

Answer: (c).To evaluate the quality of a test set Explanation:In mutation testing, a number of variants of a program are generated and tested using a given test set. The results of the test set are used to determine the quality of the test set by determining the number of live mutants, which is referred to as the mutation adequacy score.

Q336.

How are mutants generated in mutation testing?

By mechanically applying a set of simple transformations

By manually changing the program code

By using a specialized tool

By testing the program multiple times

Discuss

Answer: (a).By mechanically applying a set of simple transformations Explanation:In mutation testing, mutants are generated by mechanically applying a set of simple transformations called mutation operators. These mutations slightly differ from the original version of the program.

Q337.

What does a low quality test set indicate in mutation testing?

A high number of dead mutants

A high number of live mutants

A high number of equivalent mutants

A high number of total mutants

Discuss

Answer: (b).A high number of live mutants Explanation:In mutation testing, if a test set leaves many live mutants, then it is considered to be of low quality since it is not able to discriminate between all kinds of variants of a given program. The mutation adequacy score is calculated based on the number of dead mutants.

Q338.

What are the two major variants of mutation testing?

Strong mutation testing and average mutation testing

Weak mutation testing and average mutation testing

Strong mutation testing and weak mutation testing

Strong mutation testing and aggressive mutation testing

Discuss

Answer: (c).Strong mutation testing and weak mutation testing Explanation:There are two major variants of mutation testing, strong mutation testing and weak mutation testing.

Q339.

In strong mutation testing, what is required for the tests to produce?

Different results for program P and its mutant P0

Same results for program P and its mutant P0

Different results for component T and its mutant T0

Same results for component T and its mutant T0

Discuss

Answer: (a).Different results for program P and its mutant P0 Explanation:In strong mutation testing, tests are required to produce different results for program P and its mutant P0.

Q340.

In weak mutation testing, what is required for the tests to produce?

Different results for program P and its mutant P0

Same results for program P and its mutant P0

Different results for component T and its mutant T0

Same results for component T and its mutant T0

Discuss

Answer: (c).Different results for component T and its mutant T0 Explanation:In weak mutation testing, tests are only required to produce different results for component T and its mutant T0.
