The entire kata should be rejected, as over time, several other very similar kata's got approved, making this one a net-0 addition to the database.

JS new test framework required.

Input validation requirements should be dropped, they add nothing to the task.

Additionally, negative shifts are perfectly valid (and so are shifts greater than 35, though other opinions may be available there). Certainly they make more sense than allowing consecutive dots.

Random tests now added

• The instructions say to include "any and all spaces" but you're right about leading dots and consecutive dot separators; I'll modify the descrption
• see first point
• good point, I'll stop discriminating against empty text

Thanks!

Needs random tests

• Leading spaces/dots are not specified anywhere
• Consecutive dot separaters are not specified anywhere either
• Why empty ciphertext should return null? Empty ciphertext has a one-to-one correspondence to empty text. I don't think you should discriminate empty text ;-)
