TestStand process models invoke model plug-ins by calling the following set of optional entry point sequences with a pre-defined set of parameters at specific points in the testing process.

  • Model Plugin – Configure Standard Options
  • Model Plugin – Configure Additional Options
  • Model Plugin – Initialize
  • Model Plugin – Begin
  • Model Plugin – Pre Batch
  • Model Plugin – Pre UUT
  • Model Plugin – Batch Start
  • Model Plugin – UUT Start
  • Model Plugin – OnTheFly Step Results
  • Model Plugin – UUT Done
  • Model Plugin – Batch Done
  • Model Plugin – Post UUT
  • Model Plugin – Post Batch
  • Model Plugin – End

To simplify the model plug-ins you create, implement only the entry points you need to perform specific tasks. The Configure Standard Options and the Configure Additional Options entry points provide functionality you invoke to allow end users to edit a model plug-in configuration. Process models invoke the remaining entry points at run time from the locations shown in bold text in the following tables.

Note The run-time order is the same for the Test UUTs and Single Pass entry points except that the Single Pass entry point does not loop on UUTs or batches.
