rfc_metric

Response For a Class (RFC) metric. The score is the number of distinct predicates in the response set: the locally defined (non-auxiliary) predicates plus all distinct predicates they directly call or update. Protocols are not scored as they cannot define predicates. The score is represented by a non-negative integer.

Remarks:

• Response set: The response set RS(E) for an entity E is the union of its locally defined (non-auxiliary) predicates and all predicates directly called or updated by those predicates.

• Score interpretation: Higher scores indicate entities with more potential execution paths in response to a message, which may increase testing effort.

• Aggregation: When computing scores for files, directories, and libraries, the individual entity scores are summed.
