Estimating software fault-proneness for tuning testing activities

The article investigates whether a correlation exists between the fault-proneness of software and the measurable attributes of the code (i.e. the static metrics) and of the testing (i.e. the dynamic metrics). The article also studies how to use such data for tuning the testing process. The goal is not to find a general solution to the problem (a solution may not even exist), but to investigate the scope of specific solutions, i.e., to what extent homogeneity of the development process, organization, environment and application domain allows data computed on past projects to be projected onto new projects. A suitable variety of case studies is selected to investigate a methodology applicable to classes of homogeneous products, rather than investigating if a specific solution exists for few cases
