Tool Support for Unit Testing of Aspect-Oriented Software

In this paper, we present a data ow based unit testing approa h and its tool support for aspe t-oriented software. Our approa h tests two types of units for an aspe t-oriented program, i.e., aspe ts that are modular units of ross utting implementation of the program, and those lasses whose behaviors may be a e ted by one or more aspe ts. We use the ontrol ow graph as a basis to ompute def-use p...

Data Flow Testing of Aspects

In this paper, we present a dataow based approa h to testing aspe ts. Our approa h onsiders three levels of testing for aspe ts, i.e., intra-module testing, inter-module testing, and intra-aspe t testing. For an individual module (i.e., a pie e of advi e, an introdu tion, or a method), or a publi module along with other modules it alls in an aspe t, we perform intra-module testing or inter-modu...

Composable Designs with UFA

ABSTRACT While aspe t{oriented approa hes draw their strength from improving modularity at the sour e ode level, their a eptan e for wide spread appli ation depends on a seamless embedding into the software life{ y le. When striving for an appropriate design notation for AOSD it is important to arefully balan e the abstra tion required by design with the pre ision required for implementing a gi...

A Bayesian Networks Approach to Reliability Analysis of a Launch Vehicle Liquid Propellant Engine

This paper presents an extension of Bayesian networks (BN) applied to reliability analysis of an open gas generator cycle Liquid propellant engine (OGLE) of launch vehicles. There are several methods for system reliability analysis such as RBD, FTA, FMEA, Markov Chains, and etc. But for complex systems such as LV, they are not all efficiently applicable due to failure dependencies between compo...
