rspec delegates ==() to the objects being compared. It's up to library providers and users to override ==() in a way that is sane in a given context. Assuming a single BigDecimal attr named amount, something like this: def ==(other) self.attributes.merge(:amount => BigDecimal.new(self.amount.to_s)) == other.attributes.merge(:amount => BigDecimal.new(other.amount.to_s)) end HTH, David _______________________________________________ rspec-users mailing list rspec-users@rubyforge.org http://rubyforge.org/mailman/listinfo/rspec-users
