1. A computer-implemented method comprising: utilizing a computer to perform: creating a test executive sequence, wherein the test executive sequence includes a first plurality of steps to be performed by a test executive engine to test a unit under test (UUT); and configuring the test executive sequence with a process model, wherein the process model includes a second plurality of steps to be performed by the test executive engine before and/or after executing the first plurality of steps, wherein the process model is configured to accept process model plug-ins to define the second plurality of steps, wherein said configuring the test executive sequence with the process model comprises selecting one or more process model plug-ins for the process model, wherein each process model plug-in includes two or more of the second plurality of steps; wherein the one or more process model plug-ins include a first process model plug-in configured to store and/or process test result data dispatched to the first process model plug-in in chunks, wherein chunk size is controllable by an auto-tuned threshold that is based on time measured for the dispatch and processing of prior results.
