Testingv1

Debugging and writing tests.
A few things:

1.  The migration name should be more specific.  What are you changing, exactly?  I can't tell by looking at this migration alone.  Name the migration something like `ChangeKitchenDescriptionToText`.
2.  You need both an `up` and `down` migration in this case because the `change_column` call alone doesn't contain enough information to undo itself — it doesn't know what the schema was like _before_ it was called.

    ```ruby
    def up
      change_column :kitchens, :description, :text, :null => false
    end

    def down
      change_column :kitchens, :description, :string, :null => false
    end
    ```
