The Ohce kata, a short and simple exercise to practice outside-in TDD using test doubles
Published by Manuel Rivero on 25/05/2016
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.
- When you start oche, 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 >!
- When you introduce a palindrome, ohce likes it and after reverse-echoing it, it adds ¡Bonita palabra!
- 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
I hope you enjoy doing it.
