Re-raised as an issue.
No random tests.

When i submit at first,i find that my code must note the uppercase and lowercase letters.
In my opinion it could be nice to add a test with a randomly generated cipher code in order to avoid solutions with a hard-coded code.
Gotcha, thanks for the feedback. I wanted to take a shot at creating a simple one to try it out, I'll see if I can make the changes you mentioned.
Fairly straightforward exercise. To make it a little more interesting, you could add randomly-generated tests.
The description could use some work, too. You should explicitly explain what is expected, such as using the superSecretChars array to know which characters to convert into which characters.
