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). In a nutshell, the script goes to a static page,
collects the links, visits each linked page and verifies an item - it
has been significantly dumbed down for the purpose of this question
and I have tested this simplified version to make sure it gives the
same output.
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. Is it an issue with my
organization/format, or something else?
**** Again, if I explicitly describe an array in place of the
variable, the script works ****.

$LOAD_PATH.unshift File.join(File.dirname(__FILE__), '..') if $0 ==

include ExHelper
before(:all) do
setup
collect_global_countries
end
@countries.each do |name, link|
describe name do
it "should contain the word #{name} in the title" do
@browser.goto link
@browser.div(:id, /content-content/).text.should include(name)
end #it
end #desc

@browser.add_checker lambda {|b| b.text.should_not include('The

@countries.should be_empty
