I can pass the simple test but when I try to pass off I get: After applying rank of -8 the resulting user rank was expected to be -8, but was actually <bound method User.rank of <__main__.User object at 0x7eff798e9ac8>>: <bound method User.rank of <__main__.User object at 0x7eff798e9ac8>> should equal -8 and I don't know what that means/how to fix. Any ideas?

Why/how is test.assert_equals(solution(rng, -1, 'a'), 3) a valid test? If the index is out of range it should return the default value, which is 'a'.

If you look at the example I try to show what I mean. Say you have an image:

A B C
F G H 
K L M
N O P

G and L are the only pixels with 8 neighbors present but each pixel still needs 8 for the filter to work. A only has 3, so the other 5 have to come from somewhere else; for this algorithm you should use the edges/corners own values. So with A the other neighbors in relation to the whole image (besides B, F, and G) will look like:

A A B
A A B C
F F G H
  K L M
  N O P

They both expect int values. Why do you think one or the other expects float values?

I copied the suggested fix to the solution, and just barely to the Test Cases

I have modified/fixed the tests so this no longer works

I added a clarifying bullet point, does this help or is more needed?

There are some random tests, do you mean with random input as well as length?

The example test case of justify('123 45 6', 7) expects 123 45\n6 but the rules say: '\n' is not included in the length of a line. How is 123 45 of length 7 (it looks like length 6 to me)? Shouldn't it be 123__45 (I can't seem to show two spaces in this so I'm using underscore_ but the point remains)?

Can you remove Please rank and upvote kata. Thanks. because it isn't part of the description. If users like it they will upvote it.

fixed

Can you add some more example test cases and then some more test cases? Maybe have a randomly filled array.
