Selecting relevant tests to quickly assess code stability

摘要

A data processing system obtains a delta between a first version of a target program and a second version of the target program, wherein the target program has been tested by a plurality of test routines. The data processing system obtains test coverage data that has been generated for the plurality of test routines, the test coverage data for a test routine identifying lines of code of the target program that have been previously tested by said test routine. The data processing system ranks the plurality of test routines based on the test coverage data and based on the delta. The data processing system selects one of the plurality of test routines based on the ranking and executes the selected test routine on the second version of the target program to determine code stability of the second version of the target program.
