done for python.

That would be great, but they would also need to build their own parser/engine.

It was nice to be able to re-use code from Decode Morse Code basic. Thanks!

It's because you're printing the result, not returning it.

Added custom error messages to all tests where it may not obvious (e.g. from test.it header) what's being tested.

Did you figure it out?

@FArekkusu: Well... all this would have been constructive in beta phase but now it demands too much time for one only man (except, maybe you:-) and 29 languages.

From point of view, it IS cheating.

Most of the time you need to find the algorithm to fill the pre-calculated table unless there are very few tests or you have the patience to attempt the series of random tests one by one...

Unfortunately, I don't have the resources to refactor solutions in so many languages

Neither do I.

The random tests are not really random, and can be easily bypassed by table of pre-calculated values.

Until now a table of pre-calculated values has never been considered as cheating.
I will be happy if you feel like adding such tests:-)

this allows important bugs like checking after the iteration inside the cycle to slip through

I am sorry but I don't understand what you mean. Maybe you could be more explicit?

Looks good, but I'm not 4k honor either.
BTW, I don't really understand how your random_tests etc functions call themselves. lol.
