You're defining the @countries instance variable outside of any method.
You're making @countries an instance variable of whatever 'self' is in the
describe block (which appears to be a class or a module), which is not the
same thing that your methods are being called on (presumably an instance of
that class or a class including that module). If you want 'countries' to be
the same across all instances of the class, use a class variable. If you
want it to be the same throughout the program, use a global. If it should be
per-instance, use an instance variable defined in some method of the class
(#initialize, most likely).
