JS test gen does not obey given constraint:

Following this rule, each number tested begins with encoded text and ends with an encoded number.

After the text, there is a binary number.

Testing for '1051209811098120113115108121126110981198106105112122117981198116102108124981001000010010098114110120119108101121111114116'
It should work for random inputs too - Expected: 'et, 6, tmohuzj, 3, felvq, 3, pbhx, 9252, njtshauknp', instead got: 'et, 6, tmohuzj, 3, felvq, 3, pbhx, 9252'

expected answer ends in text, it should end in a number

Ruby as well:

expected: "opbkrfrpk, 542, toixqsrtx, 4, hfvzzgyiuy, 344, uvr, 7, krrk"
     got: nil

(compared using ==)

and Crystal:

Expected: "stxaifmr, 6, zqnigbynah, 6425, albief, 1098, etmf, 788, gxxbuyvc, 84, uksexpybwkyei"
     got: nil
