The present invention may be a method, a system, and/or a computer program product. An embodiment of the present invention provides a computer-implemented method for associating one or more test cases with one or more source code parts for a test target, or vice versa. The method comprises the followings: obtaining one or more historical data in which one or more modification histories made in one or more source codes are associated with one or more test operation histories made in the test target after the one or more modifications; for each of the historical data, determining whether the test operation history has one or more parts which are identical or similar with those in one or more test cases; and if the determination is positive, associating the one or more test cases with one or more source code parts in the one or more modification histories which have been associated with the test operation history, or vice versa.

Association between a test case and source code

One or more previous actual results are retrieved from a software test. The longest common subsequence of data of the one or more previous actual results is determined. The longest common subsequence of data is removed to create remaining common data. The remaining common data is classified resulting in a matched portion of data and an unmatched portion of data. Classification is done by dynamic programming. Matched portions of data are identical. Unmatched portions of data are different. If an existing class exists, unmatched portions of the remaining common data are applied to the existing class. A new class of data is created. The unmatched portions of the remaining common data not applied to an existing class is applied to the new class. An expected test result is created using the longest common subsequence of data, the matched portions of the common data, and the classified common data.
