Overview
This is a description of the back end of the system tests. They consist of a perl module, several perl scripts and some root macros. The bulk of the original development was by Karl Young. You can find a copy of the documentation he wrote attached to this page (you'll notice that these pages bear some similarities to his work!)
...
The EMtests, GRtests and BTtests directories contain one directory for each test type used for the EngineeringModel, GlastRelease and BeamtestRelease packages respectively. The exec directory contains the perl scripts that run the tests. The output of the tests (root files and run log and summary) ends up in subdirectories of GlastRelease, EngMod or BeamtestRelease.

Running the system tests
The system tests are configured using a configuration file. An annotated example can be found in /nfs/farm/g/glast/u17/systests/src/exec/Config_example.txt.

Skipping the Gleam step (
...
MC generation, digi, recon, and merit)
If the full root mc, digi, recon, and merit trees already exist and are stored in the systests db and you wish to simply regenerate the histograms you can do:Wiki Markup
| Panel | ||
|---|---|---|
| ||
> cd $SYSTESTS/GlastRelease/<test_name> |
...
.sh Config_rootonly.txt |
This will access the database to find the locations of the files containing the root trees root files that were already produced by GLEAM and will regenerate the system test histograms. This is very convenient if for testing and updating the RootAnalysis macros have been altered..
