• description should be language-agnostic (No need to mention min_repeating_character_difference(text) in description)
• fixed tests to be included in full tests suite.

The "difference between the indices of these symbols" as applied to the input string "aa" is not 0, but 1. The index of the first "a" is 0, and the index of the second "a" is 1. The difference between 1 and 0 is 1, not 0.

hello again, random tests have been added

hello, thanks for the note, this is my first kata and I don’t know how to do a random check yet, I did the check intuitively by looking at the code example

This is most likely a sock puppet account of the kata author, since they submitted an exact same solution as the kata author's solution, which is pretty much impossible to happen.

There are no random tests.

Unrelated, but test code is written in a interesting way:

    def do_test(input, expected):
        num = min_repeating_character_difference(input)
        if num == expected:
            test.assert_equals(num, expected)
        else:
            test.assert_equals(num, expected)

It's just test.assert_equals(num, expected), both branches contain the same code.

Good kata for its level, suitable for practicing topics such as string
