{{Short description|Software engineering concept}}
'''Feature interaction''' is a [[software engineering]] concept. It occurs when the integration of two features would modify the behavior of one or both features.
Line 4 ⟶ 5:
This definition of ''feature interaction'' allows one to focus on certain behavior of the interacting features such as how their response time may be changed given the integration. Many researchers in the field consider problems that arise due to change in the execution ''behavior'' of the interacting features. Under that context, the ''behavior'' of a feature is defined by its execution flow and output for a given input. In other words, the interaction changes the execution flow and output of the interacting features for a given input.
==Example==
Line 13:
In this situation, it is possible that the system’s decision will be made in a [[Nondeterministic algorithm|non-deterministic]] fashion due to [[Concurrency (computer science)|race conditions]] and other design factors. The consequences of feature interactions can range from minor irritations to life-threatening software failures, and therefore there is ongoing research that aims to find ways of ''detecting'' as well as ''resolving'' feature interactions.
