The Ohce kata, a short and simple exercise to practice outside-in TDD using test doubles

I created this short and simple kata to practice outside-in TDD using test doubles for the mentoring Álvaro and I are doing in Magento Barcelona:

ohce is a console application that echoes the reverse of what you input through the console.

Even though it seems a silly application, ohce knows a thing or two.

1. When you start ohce, it greets you differently depending on the current time, but only in Spanish:
   • Between 20 and 6 hours, ohce will greet you saying: ¡Buenas noches < your name >!
   • Between 6 and 12 hours, ohce will greet you saying: ¡Buenos días < your name >!
   • Between 12 and 20 hours, ohce will greet you saying: ¡Buenas tardes < your name >!
2. When you introduce a palindrome, ohce likes it and after reverse-echoing it, it adds ¡Bonita palabra!
3. ohce knows when to stop, you just have to write Stop! and it'll answer Adios < your name > and end.

This is an example of using ohce during the morning:

$ ohce Pedro
> ¡Buenos días Pedro!
$ hola
> aloh
$ oto
> oto
> ¡Bonita palabra!
$ stop
> pots
$ Stop!
> Adios Pedro
