Thanks @daylerees! I'm going to leave this open for a bit, I might cherry-pick your daylerees@e7cc693 into a PR with a few tweaks and other alternatives.

[haacked]

A .NET implementation (in C#) is here: https://github.com/haacked/scientist.net

[joealcorn]

I'm working on a Python version as well https://github.com/joealcorn/laboratory

[jesseplusplus]

I was also alerted to a Node.js version that @Trello has created and used: https://github.com/trello/scientist

[MadcapJake]

Just finishing up a few remaining tests and I'll have a complete rewrite in Perl 6: https://github.com/MadcapJake/Test-Lab
Edit: This is now completed and is a really close copy of Scientist including a translation of all Scientist's tests.

[rawls238]

I'm starting to work on a Java version here: https://github.com/rawls238/Scientist4J

[tomiaijo]

I have a somewhat complete C++ port here: https://github.com/tomiaijo/scientist

@tomiaijo , @rawls238 , @MadcapJake, @jesseplusplus , @joealcorn , @haacked , thank you for porting, report and spread a idea of scientist over whole a world

[rawls238]

any reason not to merge this in + add the additional ports?

[tom-pang]

There's a clojure port that's been around a while: https://github.com/yeller/laboratory

[bugthesystem]

Node/js implementation (in ES6) is here: https://github.com/ziyasal/scientist.js

[lancew]

Adding to the list:
Perl 5 : https://github.com/lancew/Scientist
Perl 6 : https://github.com/lancew/ScientistP6 (Smaller less feature complete compared to @MadcapJake 's Test::Lab)
