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. In previous work, we proposed the use of component metacontents---additional data and methods provided with a component, to support software engineering tasks. In this paper, we 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.
