too easy for 4kyu

Python tests are still broken, random portion tests negative page indexs which should return -1 but tests expects different answer.

No test cases for negative numbers, also description should state that you are rounding up.

Details say cases with all be > 5, this is not true. Dictating behavior for case of size = 0 would be good as it doesn't specify in the details but it the first case when submiting solutions, which also does not provide feedback.

0000000000
.........0
00000000.0
0......0.0
0.0000.0.0
0.0..0.0.0
0.0....0.0
0.000000.0
0........0
0000000000

Is it still this? becuase this is correct, turning once more would put a 0 adjacent to 2 other 0's.

Consider more examples or more explicit definitions of what you want the functions to do, shouted and whispered are clear but I couldn't tell if spoken was meant to return the message unaltered or capitalize the first letter or ...

Weird, I don't see it anymore. Language was python. Must have been some local weirdness.

I guess I interperated it as asking to only display that behavior when two words are specifically seperated by a hyphen as that would be the most reasonable character to be seperating two objects in practical applications, I can see how I was mistaken but I would still suggest clarifying in the description, or maybe just add an example showing the punctuation other than hyphens should be preserved. Thanks for taking the time, nice kata.

Consider changing test cases, as the currest ones will validate code that simply reversed the input.

test cases should be
test.assert_equals(rot13("test"),"grfg")
test.assert_equals(rot13("Test"),"Grfg")

not

test.assert_equals(rot13("test","grfg"))
test.assert_equals(rot13("Test","Grfg"))

Base code already provides 90% of the solution, consider removing some?

Should mention in the description that punctuation should be preserved, I got error
"Input: the; : 'the' should equal 'the; '"

edit: maybe the tests are just bad because it also tells me balloon'doggy => b5n'd3y, and "Input: monolithic, is'sits'is: a; balloon-monolithic, : 'm8c is s2s is a b5n-m8c' should equal "m8c, is's2s'is: a; b5n-m8c," which from the description seems wrong.
