As businesses strive to keep pace with the rapid evolution of web technologies, their efforts to maintain automated regression testing strategies are being hindered. Technological migration of a web application can lead to test scripts becoming incapable of validating the migrated application due to differences in the testing platform. Regression tests that are still applicable to the application would therefore have to be re-written to be compatible with the new technologies. In this paper, we apply a model-driven approach to the development of automated testing scripts for validating web applications from the client-side. We define a meta-model using UML 2.0 profiles, and describe the model transformations needed to automatically port regression tests to various platforms. A prototype of the test implementation for an e-commerce application is presented to demonstrate the feasibility of the approach.
