Estimating the term…
The subject disclosure is directed towards a technology in which a first software version (e.g., build or check-in) that corresponds to a failure/regression is automatically identified. Software versions associated with a development order are automatically loaded and tested according to a search plan that narrows in on which version a failure condition first appears. For example, a binary search may be used that looks back to a previous version when a failure is detected on a tested version, or moves to a subsequent version when the failure is not detected. The search plan allows multiple test machines run tests in parallel on different versions, and adapts to the number of test machines available for testing.
A method performed at least in part on at least one processor, comprising, searching among software versions to determine a software version that corresponds to a failure condition, including loading a plurality of machines with different versions, in which different versions are based upon a search plan and a number of machines available, running a test on one or more of the loaded versions to detect whether the failure condition occurs on each tested machine, and if so, narrowing the search based upon the search plan until a version or range of versions is identified corresponding to where the failure condition first occurred.
A system comprising, a regression detection tool, the regression detection tool coupled to a plurality of test machines and configured with logic that when executed causes a plurality of different software versions to be loaded on the test machines, and wherein the logic is configured to search for a narrowed subset comprising at least one version that corresponds to a failure condition based upon results of running a test job on the different software versions.
One or more machine-readable storage media or logic having—executable instructions, which when executed perform steps, comprising:
