Review Summary
I am requesting changes because there is a clear checklist violation that is treated as a core requirement, not just a style preference. Your tests correctly cover the required behaviors of split_integer (sum, equal parts, ordering, max–min difference, and behavior when value < number_of_parts), so functionally you’re in good shape. However, in app/test_split_integer.py, several tests (for example in test_parts_should_be_sorted_when_they_are_not_equal and test_should_add_zeros_when_value_is_less_than_number_of_parts) use the pattern result = split_integer(...); assert result == ..., which directly matches the “Bad example” from [CHECKLIST ITEM #1] about unnecessary variables in simple tests.
To fix this, remove the temporary result variables in the simple assertion cases and assert directly on the function call, such as:
assert split_integer(17, 4) == sorted(split_integer(17, 4))- or restructure so you compute derived values inline without first storing the raw result in a variable when it’s only used once. You can still introduce variables when they make the test clearer or avoid repeated complex expressions, but for these straightforward equality and ordering checks, the checklist expects direct assertions. Once you adjust those tests to comply with the checklist, the overall test suite will both meet the functional requirements and align with the required testing style. You’re very close—this is mainly a small but important style correction tied to the project’s explicit rules.

This matches the "Bad example" pattern from checklist item #1: result_of_testing_function = some_function_to_test(); assert result_of_testing_function == [10]. For these simple assertions on ordering and max-min difference, avoid introducing an intermediate result variable and assert directly on the function call or refactor to not mirror the bad example structure.

Same issue as above for the other calls in this test: assigning result = split_integer(...) and then immediately asserting on it violates checklist item #1's guidance against unnecessary variables in simple tests.

This test also uses the result = split_integer(...) pattern multiple times before simple assertions, which violates checklist item #1 about avoiding unnecessary variables for simple tests. Consider asserting directly based on split_integer(...) or restructuring to avoid this pattern.

Review Summary
Your solution is approved because the tests for split_integer now fully cover the required behaviors and follow the testing checklist. You verify that the sum of the returned parts equals the original value, that values are split as evenly as possible with max–min difference <= 1, and that the list is sorted in ascending order. You also correctly cover key examples like 8/1, 6/2, 17/4, and 32/6, as well as the case where value < number_of_parts, ensuring zeros are handled while all constraints still hold. The tests use plain pytest style assertions without unnecessary temporary variables, satisfying [CHECKLIST ITEM #1] and [CHECKLIST ITEM #2], and there are no leftover debug prints or helper code. Overall, the tests are clear, focused, and aligned with the task requirements and style expectations—nice work tightening them up.
