Method and apparatus to automatically identify specific code changes to probabilistically exclude from regression

摘要

Techniques for efficiently isolating software regressions are provided. In one embodiment, it is determined that a particular regression is present in a particular build of a software system. A set of candidate code components that may have caused the particular regression is identified. In accordance with an order established based on historical data for the software system, one or more intermediate builds each involving some subsets of the candidate code components may be tested to identify a set of suspect code components that caused the particular regression. For each candidate code component that is not in the set of suspect code component, a likelihood factor associated with that candidate code component is decremented.
