You might want to enforce the use of regex because some people get around with .slice and equality operators (e.g <, >, <=, >=) to parse the numbers.

Alright, enough regex for today.

No random tests in Coffeescript

• the description isn't giving the info that the output should finish with a new line
• the tests are really bad:
  • my solution passes the tests without that last char
  • but the sample tests are specifically wanting it
  • there are close to no chances that the random tests catch that error
  • no fixed tests
  • the tested coordinates are ranom, but not the inputs
  • (why the hell not testing the full board string!??? xo )

I added tests that check for valid months and days.

You are only ever provided with a single dimension.
What does "checking the color of 8 X 3 field" mean when you are given a dimension of 8. It will be an 8 x 8 square.
How useful is this message, "Here you should have whitespace - Expected: 'white', instead got: 'black'"?

fixed;-)...

PHP translation kumitted. Please check and approve

• Needs example tests
• Which tile is whitespace, and which tile is #? The description only said the two tiles corresponds to them, but never said which one is which.

Hello! Nice kata.

My solution doesn't check for <= 31 for the date, but it still passed the tests.

Nice exercise, but the tests don't cover all possible "corner cases". As a result some solutions that don't follow the description are accepted.
Things the tests don't check:

• String with 2-digits Years should be accepted
• Strings where the Month or the Day is '00' should be rejected
• Strings where the last 4 characters contain something different from numbers should be rejected

Yeah I know it's just for testing :), now fixed and working, test cases seems works too. Thx for your effort.

Yes it's right your solution passes without new lines, and now I've changed that. But have you tried console.logging your string? It does not look like a chessboard. That's why it fails the 8x3 check.
