Adding BDD test with cucumber to demonstrate different way to use in OutsideIn TDD

[cuvaalex]

The idea it's to add Cucumber to demonstrate OutsideIn TDD way. It would most probably showed in the 23 Nov 2022 meetup.

Job to be done :

• describe the kata with *.feature
• implements different approach from: the present view, port and use case

@cuvaalex this is a great idea, looking forward to it.

Quick note: I've done structural updates to the project (converting into multi-module project) to make it proper hexagonal architecture... hence if you're working on this ticket, could you update your fork...
