We demonstrate the soundness of these findings in several ways. We fur-ther stressed our algorithms and mechanisms by applying them recursively towards gaining a self-healing property for the repair service itself. Although our experience was done in the Jade context, using the Fractal component model, we believe our findings to be general to architecture-based management systems using reflective component models.
Figure 5. AMRM models in different levels of abstraction Figure 5 shows the outline of the procedure we followed for the component integration and communication refinement. The first step is to integrate and link them with abstract associations in a conceptual model. We implement the concrete mess We implement the concrete message passing semantics and do communication refinement.
Figure 6 shows the UML class diagrams and the block diagrams for the component integration and the communication refinements. Line 10 instantiates a test bench that aggregates a configurable stimuli list. Line 13 to 15 are procedure calls that set the associations between the components for communication.
The process is to re-implement these procedures, as the abstract associations are refined. Bertolino, F. Corradini, P. Inverardi, H.

The SA describes a system in terms of its components and connections, therefore the derived test plans address the integration testing phase. ALTSs oer specic views of the SA dynamics by concentrating on relevant features and abstracting away from uninteresting ones. Intuitively deriving an adequate set of functional test classes means deriving a set of paths appropriately covering the ALTS. In the paper we describe our approach in the scope of a Mobile agents, programs that move within a system performing a set of tasks, are an active field of research.
The focus of current research, however, is on the development of execution platforms and applications for mobile agents and not on methodologies for building agents. Creating mobile agents c Abstract - Cited by 24 3 self - Add to MetaCart Mobile agents, programs that move within a system performing a set of tasks, are an active field of research.
Creating mobile agents can be tedious and susceptible to errors. We propose a framework where the agent is composed using a welldefined set of categories of software components.
Building systems from software components has already proven useful in the context of large software systems, increasing the productivity of the development process and the reliability of the resulting system by reusing proven components.
We claim that the same holds true for the construction of mobile agents for network and systems management as well as for other domains. We have designed and implemented an agent construction toolkit the AgentBean Development Kit—ADK to demonstrate the usability and flexibility of this approach.
