There can only be up to two '=' padding, and each 'block' is 24bits, so that should explain which it is refering to right?

Really enjoyed this kata, thanks :)

It was one of those cases where I thought it would be far more fiddly than it actually needed to be, was a nice A-HA moment in my head :)

Great kata, thanks for making me finally research how you'd go about decoding Base64! :)

I'm having the same (maybe?) issue, the output frame is red while all the tests say they passed (including the Expected Errors).
There is no indication which test is failing in the output at all.

edit: was going to paste the solution here but I dont know how to add the syntax highlighting on here :)
