Quite an easy and simple kata.

C#: method name should be PascalCase (Please refer to implementation of backward compatibility here )

fixed

CoffeeScript: the range of random characters is 0 <= char code <= 1024 (but the description has 1023 as the upper bound).

CoffeeScript uses randint to generate random characters and randint includes the upper bound.

If more tweaks are required, we'll make another issue for those.

• That should be fixed, 1024 was included in random test generator, but is no longer the case.
• specific IT blocks added (with expected string) for small test cases with printable chars (narrow tests)

.

• for the "huge" strings, also the entire string in it? Maybe use "it" for all of the smaller test cases, but still group the larger ones in one "it" for the entire batch ...
• var removed from code everywhere

fixed

now that we'are at it...

• the solution setup shouldn't use var (neither the tests, but I don't see them, so...)
• can you add the expected string in it(`"${...}"`,... messages?

I updated the test order.

so I guess I have an infinite loop somewhere...

I think it's still possible to push the changes, right?

Once back up, I'll rearrange to have all batches with smaller strings before other tests.
