with Software Testing and Regression Testing Techniques

Where the creation, understanding, and assessment of software testing and regression testing techniques are concerned, controlled experimentation is an indispens-able research methodology. Obtaining the infrastructure necessary to support such experimentation, however, is difficult and expensive. As a result, progress in exper-imentation with testing techniques has been slow, and empirical data on the costs and effectiveness of tech-niques remains relatively scarce. To help address this problem, we have been designing and constructing in-frastructure to support controlled experimentation with testing and regression testing techniques. This paper reports on the challenges faced by researchers experi-menting with testing techniques, including those that in
