Test Pipelines
Use 
                  
                  RUN_PIPELINE_ONCE to run a
            pipeline once on-demand without creating a scheduled job.
                  RUN_PIPELINE_ONCE is useful for testing a pipeline before you start the
            pipeline. After you run a pipeline once to test the pipeline and check that it is
            working as expected, use RESET_PIPELINE to reset the pipeline's state
            (to the state before you ran RUN_PIPELINE_ONCE).
