Abstract: A test suite is executed to test a computer program for a plurality of variables. A variable value is generated for each variable of the plurality of variables at a predetermined location of the computer program. Whether a test included in the test suite is successful is determined. If the test is successful, the variable value is recorded as part of a success value set. If the test is not successful, the variable value is recorded as part of a failure value set. A confidence metric is calculated for the variable value. A relevance metric for each variable of the plurality of variables is measured, based on a Jaccard distance between the success value set and the failure value set. The failure value set, the success value set, the confidence metric for the variable value, and the relevance metric for each variable of the plurality of variables are presented.

Abstract: A computer-implemented method includes generating static analysis data by performing static analysis on a program. A breakpoint is set in the program automatically, by a computer processor, based on the static analysis data. The breakpoint is hit during a runtime of the program. A program bug is automatically identified at a context location of the breakpoint when the breakpoint is hit during the runtime of the program. An interactive debugging session of the program is launched automatically at the context location of the breakpoint, based on the identifying the program bug.

Abstract: According to one or more embodiments a computer-implemented method includes detecting, by a processor, an instruction to capture runtime data of a set of instructions in a computer program, the instruction detected based on a hook associated with the set of instructions. The method further includes determining whether the hook is an active expiring hook. The method further includes in response to the hook being an active expiring hook, determining a time condition associated with the expiring hook. The method further includes in response to the time condition being met, capturing the runtime data of the set of instructions in the computer program.

Abstract: Embodiments include a technique for operating a storage profiler for a computer operating system. The technique includes analyzing statements of an application to identify instructions that are associated with obtaining storage and statements that alter storage values in the obtained storage upon entry to every compile unit in the application, and overlaying storage statement hooks on the identified instructions and the identified statements. The technique also includes responsive to overlaying the storage statement hooks, updating a storage data structure based on the storage statement hooks, displaying the storage usage data as a grid map based on the storage data structure, the grid map comprising blocks associated with a storage location for system memory, and selecting a data block of the grid map for the storage usage data.
