In serarching I see about three or four people asking for this task to be explained. I also feel this task is difficult to understand what you are supposed to do. It sort of seems like the purpose might be to get you to come up with good test cases that might actually test edge cases? It is unclear, there is no tutorial linked and although I have both 1) written unit tests before and 2) dveloped a test plan with specific test cases, it is not clear what is meant. It is also confusing that this is the first challenget that doens't say "write your code here".

Python 3

Pythonista! This is very good case to demonstrate your OOP skills. Make your test class valuable for real business case:

generate the list with randmo shift and length
shuffle the list
control number of duplicates
make random sampling reproducible (use randmo.seed())

from random import seed, sample, randint
seed(250)

class TestDataEmptyArray:
    static_array: list[int] = []
    
    @classmethod
    def get_array(cls) -> list[int]:
        return cls.static_array



class TestDataUniqueValues(TestDataEmptyArray):
    static_min_val = randint(0,1000)
    static_array_ordered: list[int] = [i for i in range(static_min_val, static_min_val*100)]
    static_array: list[int] = sample(static_array_ordered, len(static_array_ordered))
    
    @classmethod
    def get_expected_result(cls) -> int:
        return cls.static_array.index(cls.static_min_val)



class TestDataExactlyTwoDifferentMinimums(TestDataUniqueValues):
    static_min_val= randint(0,1000)
    static_array_ordered: list[int] = [i for i in range(static_min_val, static_min_val*100)] + [static_min_val]
    static_array: list[int] = sample(static_array_ordered, len(static_array_ordered))

Happy pythoning!

It's actually way more complicated than I could imagine. I understand that it's important for proper business workflow, but in my case, working with specialists turned out to be a less demanding option. I've read about Payment system integration from Process MIX, and working with these specialists provided me with the best solution for my business.
