Abstract: In one embodiment, a method determines a plurality of test cases to test an application and a set of attributes assigned to each test case in the plurality of test cases. The method then calculates a test case risk score for each test case in the plurality of test cases based on the set of attributes associated with each respective test case. The test case risk score quantifies a risk in not executing each respective test case. A subset of the plurality of test cases is selected based on at least a portion of the calculated risk scores. The subset of plurality of test cases is output along with a test plan risk score that quantifies the risk in not executing test cases not included in the plurality of test cases.

Abstract: Embodiments improve efficiency of creating a risk-based Regression Testing Plan (RTP) for a new version of software, by considering historical pass/fail data of particular regression tests for earlier software versions. Factors taken into account in recommending a particular regression test may include: a number of previous RTPs for earlier versions; a number of those previous RTPs including the particular regression test; the existence of a previous failure of the particular regression test in an earlier version; a date of last failure of the particular regression test in an earlier version; the existence of a previous passage of the particular regression test in an earlier version; a date of last passage of the particular regression test in an earlier software version. Certain regression tests deemed particularly useful (e.g. by a testing authority and/or the software's owner), may be automatically included in the regression test suite and exempted from the recommendation process.
