Question

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

a.

A high number of dead mutants

b.

A high number of live mutants

c.

A high number of equivalent mutants

d.

A high number of total mutants

Posted under Software Engineering

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.
