Test.it blocks should be used in tests.

Description formatting is broken.

It allows you to pass a method in as a symbol instead of passing in a block to the method itself, which makes it automatically reflexive without any further work. Below would be the longer version of the above example for that part.

.map do |strings|
  strings.join
end

Yes, it is.

i used assert_equals instead, sorry this is my first kate, i did not know, thank you for pointing that out.

okay

Test.assert_equals(main("where over here we use ruby like vibranium",[1,2,3,4,5]), "xkgvj tzgu mith bi vvg wydb qmmh wldvfolwq")

This test case in the sample tests is wrong.

Your sample tests and fixed tests are using Test.expect (and in fact it's used in the wrong way), so any truthy value passes them.

Please fix them to be consistent with the random tests.

Isn't this just yet another Caesar cipher with a slight variation?

I just created the random test

i just updated it

Needs Random Tests.

just a little smaller but sill super cool

nice catch
