Just one of the pitfalls of using implicit relative paths. I recommend
switching to explicit paths defined as arguments or in a config file.
Otherwise, have your test script cd into the appropriate directory
before it runs the data processing script that it's testing.

It appears that you want to dynamically plan your number of tests based
on a condition. If this is the case check out the 'plan' function from
Test::More. Instead of:
use Test::More tests => $Num_Tests;
You can do:
use Test::More qw(no_plan);
# and later...
plan tests => $Num_Tests if $cond;
