Roman Numerals Kata done using TDD. Practiced the same day on a Code Dojo in JavaScript and partially inspired by Roman Numerals Kata with Commentary by Corey Haines which we have watched at the end of the Dojo.
The only interesting file is RomanNumeralsKataTests/RomanNumeralsKataTests.m.
I have practiced this kata once more (result is in RomanNumeralsKataTests/RomanNumeralsKataTests2.m) and this time did commit after each successful test implementation, so in addition to the final result the progress can be replayed.
