Review Summary

Approved because the implementation appears correct and the existing tests cover the core example behaviors and edge case. However, the tests are missing explicit assertions for the general properties required by the checklist (array type, correct length, integer elements, sum preservation, sorted order, and max−min ≤ 1). Strength: you correctly test key examples like splitInteger(6,2), (8,1), (17,4), and an edge case where value < numberOfParts. To strengthen the suite, please add property-based checks alongside the example assertions in src/splitInteger.test.js (around the existing result expectations) and consider including the missing example splitInteger(32, 6) → [5, 5, 5, 5, 6, 6]. Suggested assertions to add near those lines: Array.isArray(result), result.length === numberOfParts, result.every(Number.isInteger), sum equals value, sorted ascending, and Math.max(...result) - Math.min(...result) ≤ 1. Nice work overall—these additions will make your tests document the required behavior more robustly.

The test computes result for splitInteger(6, 2) — good. Consider adding explicit property assertions here (instead of relying only on exact array equality) to verify the checklist items: array type, correct length, integer elements, sum equals input, sortedness, and max-min <= 1. For example:

expect(Array.isArray(result)).toBe(true);
expect(result.length).toBe(2);
expect(result.every(Number.isInteger)).toBe(true);
expect(result.reduce((a,b)=>a+b,0)).toBe(6);
expect(Math.max(...result) - Math.min(...result)).toBeLessThanOrEqual(1);
expect(result).toEqual([...result].sort((a,b)=>a-b));

Adding these checks will ensure the test verifies the general properties from the task, not just one concrete output. (See checklist items 3.1–3.5.)

This expect(result).toEqual([3, 3]) is fine for the specific example, but it would be more robust to also assert the general properties (length, sum, integer-ness, sorted, max-min <= 1). That way tests document the required behavior rather than only one canonical output.

Good that you check a non-equal-parts example here. Also consider adding the additional example from the description splitInteger(32, 6) === [5, 5, 5, 5, 6, 6] to mirror the specification. More importantly, add a general-property assertion (array type, length, integers, sum, sorted, max-min <=1) either here or in a separate helper test so the checklist items are explicitly verified.

[mateacademy-ai-mentor]

The edge-case test for value < numberOfParts is present and asserts the expected array. Please also assert result.length === 5, that all elements are integers, the sum equals the original value (3), that the array is sorted, and Math.max(...result) - Math.min(...result) <= 1. These explicit checks ensure the function adheres to the task constraints for such edge cases (checklist items 3.1, 3.2, 3.3, 3.4, 3.5).
