Abstract
Techniques for isolating software regressions are provided. In one approach, QTrace is used to generate DTrace scripts to gather timing information of one or more portions of source code during a test of particular version of a program. Based on results of one or more tests of multiple versions of a program, a regression is identified with respect to a particular portion of source code. It is determined that the particular portion of source code was changed during an intermediate version of the program (i.e., between two tests). The intermediate version and/or the particular portion of source code are identified as being a potential source of the regression.
