Summary:PROBLEM TO BE SOLVED: To calculate a risk of each line of an analysis object program in such a manner that a risk of a line where a bug exists increases.SOLUTION: A test of an analysis object program is executed per test case according to test criteria given for each test case while recording a test result (success/failure) per test case and an execution frequency for each line of the analysis object program. A risk is calculated per combination of each line of the analysis object program and the execution frequency (per column of the figure) on the basis of the test result per test case and the execution frequency for each line of the analysis object program. In this manner, a risk of a combination of a line where a bug exists and an execution frequency at which a bug becomes obvious (the combination of the line of S5 and the execution frequency of 101 in the example in the figure) increases, which facilitates extraction of the bug.
