In software development, feature interaction occurs when the behavior of a software system is affected by the combination of features or inputs. Feature interaction can cause unexpected and undesirable behavior in software systems, which can be challenging to detect and resolve. Feature interaction matrices are one of the techniques used to identify and analyze feature interaction in software systems. These metrics can help identify potential problems caused by feature interactions and guide software developers in designing better systems.
What Is a Feature Interaction Matrix?
A feature interaction matrix is a table that lists all possible combinations of features in a software system and identifies any interactions between them. Each row and column in the matrix represents a feature, and the cells represent the interactions between the features. The matrix is populated by testing the software system with different combinations of features to identify any interactions that may cause unexpected behavior.
