Inside the framework package you declare $date as a lexical variable. This means that the variable is only visible inside the framework.pl file.

Inside your main package, you try to access a package variable called $framework::date. This is a completely separate variable to the lexical that you declared previously. This is why updating it has no effect on the output from testcase1 - you're updating the wrong variable.

Easiest solution is to replace the lexical variable declaration with a package variable declaration in framework.pl like this:

use vars '$date';

(or our $date if you're using Perl 5.6.x)
