Q341.
What is the main difference between strong mutation testing and weak mutation testing?

a.

In strong mutation testing, tests are required to produce different results for program P and its mutant P0, while in weak mutation testing, tests are only required to produce different results for component T and its mutant T0.

b.

In strong mutation testing, tests are only required to produce different results for component T and its mutant T0, while in weak mutation testing, tests are required to produce different results for program P and its mutant P0.

c.

In strong mutation testing, tests are required to produce same results for program P and its mutant P0, while in weak mutation testing, tests are only required to produce same results for component T and its mutant T0.

d.

In strong mutation testing, tests are only required to produce same results for component T and its mutant T0, while in weak mutation testing, tests are required to produce same results for program P and its mutant P0.

Discuss
Answer: (a).In strong mutation testing, tests are required to produce different results for program P and its mutant P0, while in weak mutation testing, tests are only required to produce different results for component T and its mutant T0. Explanation:In strong mutation testing, tests are required to produce different results for program P and its mutant P0, while in weak mutation testing, tests are only required to produce different results for component T and its mutant T0.
Q342.
What is the Competent Programmer Hypothesis in mutation testing?

a.

Competent programmers write programs that are ‘close’ to being incorrect.

b.

Competent programmers write programs that are ‘close’ to being correct.

c.

Competent programmers write programs that are completely incorrect.

d.

Competent programmers write programs that are completely correct.

Discuss
Answer: (b).Competent programmers write programs that are ‘close’ to being correct. Explanation:The Competent Programmer Hypothesis in mutation testing states that competent programmers write programs that are ‘close’ to being correct.
Q343.
What is the Coupling Effect Hypothesis in mutation testing?

a.

Tests that can reveal simple faults can also reveal complex faults

b.

Competent programmers write programs that are far from being correct

c.

Competent programmers write programs that are perfect

d.

Competent programmers write programs that are close to being correct

Discuss
Answer: (a).Tests that can reveal simple faults can also reveal complex faults Explanation:The Coupling Effect Hypothesis states that tests that can reveal simple faults can also reveal complex faults.
Q344.
What is the purpose of error-based testing techniques?

a.

To focus on error prone points in the program

b.

To test the logic of the requirement

c.

To use an input from each subdomain

d.

To achieve path coverage for the program

Discuss
Answer: (a).To focus on error prone points in the program Explanation:Error-based testing focuses on error prone points in the program, which are often found near the borders of subdomains.
Q345.
How does the program logic relate to test adequacy for the requirement in error-based testing techniques?

a.

Test adequacy equals path coverage for the program

b.

Test adequacy is independent of the program logic

c.

Test adequacy depends on the subdomains used as input

d.

Test adequacy is not related to the program logic

Discuss
Answer: (b).Test adequacy is independent of the program logic Explanation:In error-based testing, the focus is on error prone points, not necessarily the program logic. The program logic may relate to test adequacy in other testing techniques, but not in error-based testing.
Q346.
What is an ON point in error-based testing?

a.

A point just inside a border of a subdomain.

b.

A point just outside a border of a subdomain.

c.

A point on the border of a subdomain.

d.

A point not near any border of a subdomain.

Discuss
Answer: (c).A point on the border of a subdomain. Explanation:An ON point is defined as a point on the border of a subdomain.
Q347.
What is an OFF point in error-based testing?

a.

A point just inside a border of a subdomain.

b.

A point just outside a border of a subdomain.

c.

A point on the border of a subdomain.

d.

A point not near any border of a subdomain.

Discuss
Answer: (a).A point just inside a border of a subdomain. Explanation:An OFF point is defined as a point just inside a border if the subdomain is open with respect to the border, and a point just outside the border if the subdomain is closed with respect to the border.
Q348.
What is error-based testing mainly focused on?

a.

Path coverage.

b.

Error prone points.

c.

Test coverage.

d.

Test adequacy.

Discuss
Answer: (b).Error prone points. Explanation:Error-based testing focuses on error prone points, which are often found near the borders of subdomains.
Q349.
What is the nature of most test techniques?

a.

Sound and Theoretical

b.

Heuristic

c.

Based on assumptions

d.

None of the above

Discuss
Answer: (b).Heuristic Explanation:The most test techniques are heuristic in nature and lack a sound theoretical basis.
Q350.
What is the quality of manual test techniques?

a.

They are strong

b.

They rely on the qualities of the participants

c.

They are based on assumptions

d.

None of the above

Discuss
Answer: (b).They rely on the qualities of the participants Explanation:Manual test techniques rely heavily on the qualities of the participants in the test process.
