wrong task in the description... (even that...)

ok, I'll say it, sorry, but this is bullshit...

• class should be Seafood, not seafood
• constructor is not described
• no sample tests
• name of the property not tested while imposed in the description
• not enough tests (needs random ones, more fixed tests would not be useful)
• description formatting is really poor

please un-publish this...

• not enough tests (only 1!)
• no sample tests (for beginner katas, that's non sense!)
• excpected behavior not checked
• working answer available in the description.

As said by Voile before: you should learn how to create proper katas before publishing some. And you should delete those you published already (or at least, un-publish them so that you could make some changes.

Please learn how to write a good kata before your write your first kata.

In the meantime, you should consider unpublishing this kata.
