I don't know _anything_ about the composition of a perl module or how to develop tests therefore, but perhaps you can use this:

Ever tried redirecting a child stdin or stdout with open()?

open( HANDLE, "ls -l |" ) or die "Unable to exec 'ls'\n";
while( <HANDLE> ) {
#Process each line of output '$_'
}
close( HANDLE );

I do this all the time when I want to execute a child process and evaluate it's output.

HTH,
James
