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).
