"abcccabab"       3

Why is the expected result 3?

If the index is zero-based, then 3 would be the second 'c' instead of the first 'c'.

Random tests always seem to expect Diamond?

Does not award the correct statuette: 'Crystal' should equal 'Diamond'
Does not award the correct statuette: 'Bronze' should equal 'Diamond'
Does not award the correct statuette: 'Crystal' should equal 'Diamond'
Does not award the correct statuette: 'Silver' should equal 'Diamond'
Does not award the correct statuette: 'Silver' should equal 'Diamond'
Does not award the correct statuette: None should equal 'Diamond'
Does not award the correct statuette: 'Crystal' should equal 'Diamond'
Does not award the correct statuette: 'Silver' should equal 'Diamond'
Does not award the correct statuette: 'Silver' should equal 'Diamond'
Does not award the correct statuette: 'Crystal' should equal 'Diamond'

I may need a bigger hint. LOL

What exactly was being tested here??

Test Failed
  Expected: True
  But was:  False

test.assert_equals(makeFraction(.523681), (428417670197443, 818088190672896))

Why isn't the answer (523681, 999999)? That would produce the desired repeating decimal.

n: 179164078, score: 41130371602715017, expected: 25080488090337936: 25080488090337935 should equal 2.5080488090337936e+16

Why is the reference solution using floating point math when an exact integer solution is possible?

Fix the random tests to invalidate this solution:

This issue was corrected for the fixed tests but random tests still aren't testing anything.

For this "solution":

def problem(area):
    return 1

I got this result:

Random tests

The tests aren't testing anything.

I made a mistake in this solution but still passed: https://www.codewars.com/kata/reviews/66bce4158fed1ddb86d680b7/groups/66bce9654a6f487c43156bc3

Some of the edge cases may need explanation.

When the cathetus is equal to the hypotenuse, that could mean that the "other side" of the right triangles is zero, so the four right triangles are all zero-area. Then the inner square is equal in area to hypotenuse ** 2.

But the edge case tests expect 0 for the result. Why?

Still see the following in the desc:

Ensure that both a and b are always non-negative numbers.

The question remains though. Which line or line segment do you mean by "cathetus"? It could be the shorter leg or the longer leg or maybe it doesn't matter. That is unclear.

Nothing in the diagram is marked.

So which length in the diagram is b?

As a concrete example, the reason why rounding to 2 decimal places is not a panacea is there is one test where one of the values is -5.055

Depending on the order in which you do the calculations, you may get -5.05499999 or -5.055000001, which round to different results in two decimal places.
