# app/config/initializers/extra_fakeweb.rb
module FakeWeb
class Registry
def unregister_uri(method, uri)
uri_map
[normalize_uri(uri)][method] = {}
end
end

def self.unregister_uri(*args)
case args.length
when 2
Registry.instance.unregister_uri(*args)
else
raise ArgumentError.new("wrong number of arguments (#{args.length} for 2)")
end
