Yes it is part of the testing infrastructure. I think we use the test
category for that, cf. this file (RuntimeStatisticsParser.java) was
originally created by JIRA DERBY-2463 which is labelled with Category
Test. The tools category is reserved for the runnable tools like ij,
sysinfo, dblook and some utilities like install_jar, export and
import.
