Component based software technologies are viewed as essential for creating the software systems of the future. However, the use of externally-provided components has serious drawbacks for a wide range of software engineering activities, often because of a lack of information about the components. Previously (A. Orso et al., 2000), we proposed the use of component metacontents: additional data and methods provided with a component, to support software engineering tasks. The authors present two new metacontent based techniques that address the problem of regression test selection for component based applications: a code based approach and a specification based approach. First, we illustrate the two techniques. Then, we present a case study that applies the code based technique to a real component based system. On the system studied, on average, 26% of the overall testing effort was saved over seven releases, with a maximum savings of 99% for one version.
