Abstract
Techniques for efficiently isolating software regressions are provided. A system test tool determines that a particular regression is present in a particular build of a software system, but not in a baseline build. Using historical data, the tool determines, for each of a plurality of intermediate builds between these two builds, a likelihood that that intermediate build introduced the particular regression. A particular intermediate build can be identified as a build to be tested. Here, the particular intermediate build comprises a plurality of layered putbacks, each of which putbacks comprises one or more code changes in the software system. The tool determines, for each putback, a likelihood that that putback introduced the particular regression. A particular putback in the plurality of putbacks may be selected as a putback to be tested. In some embodiments, the particular putback is the putback that has the greatest likelihood of introducing the particular regression.
