How should I test Rails Enums? -

suppose have model called creditcard. due technical restrictions, it's best if card networks represented enum. code looks this:

class creditcard < activerecord::base    enum network: [:visa, :mastercard, :amex] end 

what should tested when using enums if anything?

if use array, need make sure order keeped:

class creditcard < activerecord::base   enum network: [:visa, :mastercard, :amex] end  describe creditcard, '#status'   let(:network) { [:visa, :mastercard, :amex] }    'has right index'     network.each_with_index |item, index|       expect(described_class.statuses[item]).to eq index     end   end end 

if use hash order not matter, value of each key, will. so, it's to make sure same number each key.
