xD nice!

To solve some kata. When you solved it, and then click Show Kata Test Cases, you will see the author's test code ;-)

How can I do that? It's my first Kata and I dont know very much about testing,
any place to grab some examples? I've looked at the codewars Docs
for the testing framework but didn't find anything about random test cases, any help would be helpfull :)

In case of input '0-d' closure should return false always,
sorry about the testcase it's my firts Kata, and dont now very well how it works, i will fix it

Input:

Input will be a string formated as follow:

• '0-9'
• 'a-z'
• 'A-Z'

is misleading and test message is contradicting itself.

/*
rangeIntBad = range('0-d')
  rangeIntBad(2) should be false
  rangeIntBad(2) expected false - Expected: true, instead got: false
*/

What is the expected behavior in this case ('0-d')?

Needs random test cases
