How do you test code that uses environment variables (PERL5LIB, PERL_LOCAL_LIB_ROOT)?

Testing code that relies on environment variables like PERL5LIB and PERL_LOCAL_LIB_ROOT can be crucial for ensuring that your Perl applications run as expected. Here’s how to approach testing with these environment variables effectively.

Example:

#!/usr/bin/env perl use strict; use warnings; # Set environment variables $ENV{'PERL5LIB'} = '/path/to/your/lib'; $ENV{'PERL_LOCAL_LIB_ROOT'} = '/path/to/local/lib'; # Your code logic here use lib $ENV{'PERL5LIB'}; use My::Module; my $obj = My::Module->new(); $obj->do_something();

In this example, we set the environment variables PERL5LIB and PERL_LOCAL_LIB_ROOT within the script. This ensures that any modules located in the specified directories are included when the script runs.
