note: some definitions local to cw:

• Issue: problem in the kata itself (description, wrong tests, wrong internal solution...)
• Suggestions: well, I guess that part is clear
• Question anything else that is related to you having a problem solving a kata -> that's you, currently.

cheers ;)

in your tests you do not have # after an uppercase to go back to lower case

what's this, then? "#44#33..." (edit: don't forget that the sample tests are just sample. That comes from the full test suite)

the test for "oen two three" is also wrong as theres a space?

from the description:

If you have 2 or more characters in a sequence that reside on the same button (refer to layout, bottom row), you have to wait before pressing the same button again. Waiting is represented by adding a space between 2 (or more) such characters. Example:
44 444 44 444 => 'hihi'

Seriously, read the specs again before beleiving that the tests are wrong. 99% of the time, that's the user that is wrong... ;)
