Logging

Logging

Each PEST run results in a run ID and logs for the harness process and each process launched by the harness. A run directory is created to contain the logs, named after the run ID. Each process results in three logs: 'processid'.log, 'processid'.meta, 'processid'.pid.

  • 'runid'/harness.log - Generated by the harness process, this shows the log location and individual process results.
  • 'runid'/'000003.235'.log - Generated by streaming a process's standard out and standard error. This is thread 3, testid 235.
  • 'runid'/'000003.235'.meta - Generated by the harness to capture a process's metadata, including its exit code, and start/stop times.
  • 'runid'/'000003.235'.pid - Generated by the harness to capture a process's process ID.

Configuration Files

PEST requires four configuration files. Each of them is copied to the run directory under the cfg directory to allow reproduction.

  • 'runid'/cfg/pest.yaml - This is a harness configuration file of no interest to the user.
  • 'runid'/cfg/'run'.yaml - This is the Test Run configuration file provided by the '-c' argument to pest.pl.
  • 'runid'/cfg/'testbed'.yaml - This is the Testbed configuration file provided by the '-t' argument to pest.pl.
  • 'runid'/cfg/'batch'.yaml - This is the Test Batch configuration file provided by the '-s' argument to pest.pl.
