Aspect-oriented software for testability

AOP is recently popular for effective technique in modularizing the crosscutting concerns such as exception handling, fault tolerance, error handling and reusability. Modularizing crosscutting concerns has a great impact on testability of software. Testability of software is the degree to facilitate testing in a given test context and ease reveling of faults. Controllability and observability are the important measures of testing non-functional requirements of software. To test software requires controlling the input and observing the output. Controllability provides a concept of probability to handle the software´s input (the internal state) while observability is to observe the output for certain input. This paper presents an overview of the use of aspect-oriented programming (AOP) for facilitating controllability to ease testability of object-oriented software, and simulation of well-mixed biochemical systems.
