  • Publication number: 20230393968
    Abstract: Various examples are directed to systems and methods for testing software. A testing system may use test case data describing a first test case failed by a first build of the software application, the first build generated by a first commit operation of the plurality of commit operations to execute a fault localization operation, the fault localization operation to identify a first suspect program element of a first build. The testing system may use the first suspect program element and commit data to select a second commit operation from the plurality of commit operations. The testing system may determine an error-inducing commit operation from the plurality of commit operations and executing a corrective action.
