An update for this issue. This script works, but only if I
explicitly define
the array that I'm iterating over (][countryname, url]].each do,
rather than
@countries.each do).
Can someone help me understand why my array here (@countries) is not
recognized? I tried to instantiate it as a global variable
($countries) and
it still was not recognized. If I explicitly describe an array in
place of
the variable, the script works.
Is it an issue with my organization format, or something else?

Briefly, think of two passes over this file: the first 'parse' pass,
and the second 'execution' pass. The #before and #it blocks run during
the 'execution' pass, but the code in the #describe blocks runs in the
initial 'parse' pass. Because @countries is not created until the
before blocks run, there's no way for the 'parse' pass to know what
value it has.
That's the basic essence of your issue. I'd recommend paring this back
to a much simpler example, getting that working, then building up from
there.
I'm also not sure why you're using the SUT to generate the tests, but
that's for another thread...
cheers,
Matt
