Field help (ADSTST) 

The Test folder signifies that this folder is designed to receive a copy of the standard processes present in a patch, if this must be installed in the folder. If this flag is not set, the patch processes will only be integrated at the supervisor folder level. The fact of having this flag set makes it possible to carryout integration tests for patches in a folder. Once the patches in question have been fully integrated in this environment, it is advisable to "clean up" by deleting previously installed processes (if not, the next patch or version installation will not be taken into account by these processes, which risks the appearance of malfunctioning). A production folder must not have this flag set.
