I'm also in Ruby and passing the normal tests and then getting errors on the "random strings." The test says its expecting an empty string which doesn't make sense...... ("")

Same issue here lol. Should work for random string too - Expected: "", instead got: "jn11h2su3114vp5"

That's funny, I'm having a problem with the random tests in Ruby too, but whereas yours expected just a small part of the string, mine expected an empty string:

Should work for random string too - Expected: "", instead got: "1p1am2ge3we43v5gf6u37st8fi97w10fv11w412r6135j14an15is16ak17ki180s19"```

I have a solution which passes normal test cases but fails on random strings during submit. Here's the message I get:

Testing String citpr8cpqctev04hl12y80rij
Should work for random string too - Expected: "cj1", instead got: "cj1ii2tr3p04r858y6c27p18ql9ch10t411e012"

Is it me getting the kata in a wrong way, or is there a bug in tests? (Language used - ruby).
