Test Batch Script

The test-batch script is designed to test the processing controller logic concerning processing block dependencies.

The sequence of actions carried out by the script is:

  • Claims processing block

  • Reads value of duration parameter (type: float, units: seconds) from processing block

  • Sets processing block status to 'WAITING'

  • Waits for resources_available to be True

    • This is the signal from the processing controller that the script can start

  • Sets processing block status to 'RUNNING'

  • Does some “processing” (i.e. sleeps) for the requested duration

  • Sets processing block status to 'FINISHED'

The script makes no deployments.

Full description of processing block parameters of this script can be found at the bottom of this page.
