DYNAMIC TEST GENERATION FOR CONCURRENT PROGRAMS

摘要

A computer implemented method for dynamic test generation for concurrent programs, which uses a combination of concrete and symbolic execution of the program to systematically cover all the intra-thread program branches and inter-thread interleavings of shared accesses. In addition, a coverage summary based pruning technique, which is a general framework for soundly removing both redundant paths and redundant interleavings and is capable of speeding up dynamic testing exponentially. This pruning framework also allows flexible trade-offs between pruning power and computational overhead to be exploited using various approximations.
