Scalable COncolic testing for REliable Software (SCORE)

Scalable COncolic testing for REliable Software (SCORE)


By utilizing distributed computing nodes, SCORE automatically generates a large number of test cases very fast, each of which explores a unique execution path of a target C program.  The SCORE framework employs a distributed concolic testing algorithm that can utilize a large number of computing nodes in a scalable manner to achieve (1) a linear increase in the speed of test case generation as a number of distributed nodes increases and (2) low communication overhead among distributed nodes.

SCORE overview


For example, the following graph illustrates the speed-up of test case generation for 6 SIR benchmark programs achieved by SCORE as a number of clients increases. For example, SCORE with 256 client nodes generates test cases for vim 245 times faster than SCORE with 1 client on Amazon EC2.

SCORE speed-up graph

Details of SCORE and related empirical study on the SIR benchmark programs can be found from a paper A Scalable Distributed Concolic Testing Approach: An Empirical Evaluation (ICST 2012).
