My test was to generate a version header file with an unmodified version of genVersionHeader.pl and compare it with a header file generated with a version of genVersionHeader.pl which has $/=''; at the beginning and to check that the two files are identical.
I did something like this:
cd <some repo>
$EPICS_BASE/bin/$EPICS_HOST_ARCH/genVersionHeader.pl -t . v1.h
This generates a file 'v1.h'. Then I do the modification and generate a file v2.h and compare the two. I did this for several repositories of each type.
