This issue is also fixed, now it uses appropriate information.

Length of multiline solutions is correctly identified as too large, but not presented correctly in failure messages:
Maximum length of characters
Current characters length 19 should be less or equal than 75

• JavaScript tests should use Chai assertions instead of obsolete CW framework [Finished OK]
• Inputs presented with failure messages would be really helpful [Finished OK]

The above are implemented OK now and entire solution is more compatible with other nodejs versions as well.
Also: works with chai assert and there are more informative messages on most cases.

Good to know that lo_ can now be used, was considering to use for similar purpose.

Changed to chai expects, asserts > compatible with v10/12 but randomizations need to be re-customized to support as such, be patient as I am currently fixing this. If there is anything easy to use for random tests on chai please suggest.

NOTE: also fixed the message mentioned.

Well noted, will fix.

Well noted, will fix.

Re-added kata with improvements/checks.

The current kata is already in js language. I will try and make this available also in PHP.

NOTE: This is a mac address converter - canonical to token ring format, if you need the program to just change a mac address in any way, this should be a separate Kata.

Will try and figure out what is wrong with these test scenarios.
Note: I added some other special cases where parsing generated /* */ causes erroneous behaviour, that might be the issue with some random tests.

This is also outlined in the description but since you have pointed out another case, I will be adjusting it accordingly if necessary.

If you have something else in mind, please feel free to point it out.

Thanks for the info, should be useful in other golf-kata.

What would you suggest for characters checking, in case you need to do golfing?

Note: This is a first attempt in cg so it could have some issues at some point.

Changed the kata description to include more details for error in input.

Some phrasing and grammar errors fixed, more detail added to explain the bits diagram.
