The execution of the first instance of the injected error results in a first code path, of the program being tested, to be followed.

Abstract: Described is a probabilistic concurrency testing mechanism for testing a concurrent software program that provides a probabilistic guarantee of finding any concurrent software bug at or below a bug depth (that corresponds to a complexity level for finding the bug). A scheduler/algorithm inserts priority lowering points into the code and runs the highest priority thread based upon initially randomly distributed priorities. When that thread reaches a priority lowering point, its priority is lowered to a value associated (e.g., by random distribution) with that priority lowering point, whereby a different thread now has the currently highest priority. That thread is run until its priority is similarly lowered, and so on, whereby all schedules needed to find a concurrency bug are run.

Abstract: A novel and useful stress test generation mechanism that is operative to divide the task of generating test case programs (files) into a first randomization stage and a second randomization stage. The first randomization stage selects the scenario and the second randomization stage generates a test case in accordance with the chosen scenario.

In stage 2, a test is randomly generated for the chosen scenario. Thus, for each scenario-dimension, one or more values are generated randomly for the chosen value-category. Once the values for the value-categories are generated, an output test file for use by the logic verification is generated.
