StringCalculator Kata at Xpug

Category: agile,bddgiordano scalzo @ 2:18 pm

Last evening the wonderful Xpug Milano hosted a Kata Meeting: three people, three language, one problem, one pomodoro each!

After the launch of http://katacasts.com/, this kind of practice has begun to spread around the world.

As far as I know, that was one of the firsts meeting held in Italy and it has been exciting (and a little scaring) to be one of the performer.

The simple problem to solve was the StringCalculator kata, proposed by Roy Osherove as simple exercise to repeat to assimilate Tdd.

Luca Marrocco performed the kata in Ruby, Raffaele Salmaso a Python version, the benevolent dictator of Xpug Milano a backup kata in Erlang, and yours truly a Scala version.

Below the live recording of my session, with errors, mistakes and pauses made during the execution:

Any kind of suggestion about the solution, the process, the way I performed are absolutely welcome.
