Impact analysis of weaving in aspect-oriented programming

An aspect-oriented (AO) program consists of aspects and a base program into which the aspects are woven. Base programs usually exist beforehand, and test cases have been made for them. It is useful for programmers to grasp the impact of weaving into the base program. The impact analysis is effective for problem determination of the defects inserted by the weaving, and for determination of the scope of the regression tests after weaving. This paper proposes an analysis method for the potential impacts on a base program by weaving.

Graphical representation and execution animation for Prolog programs

GRASP (graphical analysis system for Prolog) is a graphical environment for analyzing Prolog programs. A description is given of the ideas that enable GRASP to visualize the structure and control flow of Prolog programs. Two types of graphical representation for a Prolog program are proposed. They visualize program structure and the logical relations of predicates, and help the user to analyze a program statically. Execution animation on the graphical representations in proposed. It dynamically visualizes the control flow during execution of a program, and assists the user finding any unintended portions in the execution.<<ETX>>
