Description: With ever-increasing pressure to reduce software development costs, there is increasing focus on reuse. A component-based systems architecture (CBSA) utilises components that already exist, together with glue or adaptor elements that enable the reused components to work together. This leads to a need to verify that component behaviour will be as expected when it is reused in a new context and as component evolve.

Model differencing techniques have previously been used to study the evolution of a component. However, they can also be used in regression testing to demonstrate the behaviour of a reused component is as expected. The CHARMY framework is used to model a CBSA, specifying the topology and state-based behaviour, and to select and run test cases.

Using SYNTHESIS together with CHARMY, a system can be automatically assembled at run time from already implemented and verified components, and glue code that is correct by construction can be created automatically. This means that a system can evolve to take account of changed or replacement components without the need for costly redevelopment or retesting.

Conclusions: The CHARMY and SYNTHESIS combined framework, which includes tools from the CADP toolbox, provides both architectural analysis and code synthesis. Component selection and creation of the required glue code for a system can be completely automated, reducing development and testing time. A system that is assembled at run time can evolve automatically to take advantage of improvements in components.
