Frequently I notice in test suites that authors aren't always checking that their functions have been exported correctly to their namespace. Having a function exported accidentally can wreak havoc if you redefine a function. Below shows one way of testing this, though you will need to customize it to your situation.

use Test::More 'no_plan';
                                                                      
+          
use_ok('CGI');
ok(! defined *::param{CODE}, '&param is not exported to our namespace'
+);

# in another test file, verifying that you can import:
# (though in this example you can run these in one test file)
use_ok('CGI', ':standard') or die;
can_ok(__PACKAGE__, 'param');
                                                                      
+          
# or, if you prefer symmetry with the "not exported" test:
                                                                      
+          
ok(defined *::param{CODE}, '&param is exported to namespace');
