BUG CONTAMINATION PROBABILITY CALCULATION PROGRAM AND BUG CONTAMINATION PROBABILITY CALCULATION METHOD

摘要

PROBLEM TO BE SOLVED: To make it possible to calculate a bug contamination probability of a module, with effects of a code clone taken into consideration.SOLUTION: A bug contamination probability calculation program causes a bug module prediction device 10 to function as: an extraction unit for extracting static metrics information and code clone metrics information for each of the modules constituting a program, from the pre-revision program source code and the post-revision program source code; a prediction model deriving unit 13 for deriving a prediction model based on static metrics information and code clone metrics information for each of the pre-revision modules and presence or absence of bugs for each of the pre-revision modules; and a predictive value calculation unit 14 for inputting static metrics information and code clone metrics information for each of the post-revision modules into the prediction model to calculate the predictive value of a bug contamination probability for each module.SELECTED DRAWING: Figure 3
