Abstract

A system and method for synchronizing execution of multiple processes or threads executing to perform tests of one or more units under test. One or more synchronization steps may be included in a test executive sequence, in response to user input requesting inclusion of the synchronization steps. Each synchronization step may be configured to perform a synchronization operation, in response to user input specifying the synchronization operation. The test executive sequence may then be executed multiple times concurrently, e.g., by multiple threads or processes, and the one or more synchronization steps in the test executive sequence may coordinate the execution of the multiple threads or processes to test the unit(s) under test.
