1. A computing system comprising: a processing device; and memory having program code stored thereon that, when executed by the processing device, causes the computing system to: build a pseudo-random dynamic instruction stream that comprises instructions configured to perform a transaction execution; test the transaction execution in a multi-processing system based on the instruction stream; output a status of the test to one or more output devices; and establish a plurality of shared locations in a cache to serve as a basis for determining whether the transaction execution is successful; wherein a first processor of the multi-processing system is configured to write to each of the plurality of shared locations with first random, same data when within the transaction execution; wherein a second processor of the multi-processing system is configured to write to each of the plurality of shared locations with second random, same data when within the transaction execution, after the first processor writes to the shared locations; wherein a third processor of the multi-processing system is configured to read from the shared locations; wherein the third processor is configured to determine that the transaction execution is unsuccessful when a first of the shared locations includes the first random, same data and a second of the shared locations includes the second random, same data.
