Typo? It should $URL.

User error :) Test parameters are not visible as perl variables in a
test.  They are different things.

But you can do something like

$MY::URL = 'http://www.yahoo.com';
$webtest->run_wtscript($file);

and in your tests use

url = "$MY::URL/purchase.cgi"

Note that I have to use fully qualified names as Perl code in wtscript
files is run from different scope and package then caller code. You
can replace package name MY with any other but it must be a fully
qualified name.

I'll consider adding a feature which would make passing Perl variables
to tests easier. Something like

$webtest->run_wtscript($file, { perl_vars =< {URL => $URL}});
