1-3: Proper import structure established.The imports are correctly structured, with testing utilities from 'vitest' and the function under test from a relative path.
4-10: Well-structured test suite with comprehensive basic test cases.The test suite is organized using proper describe and it blocks, with clear Korean descriptions of what's being tested. The basic functionality tests cover multiple positive number combinations.
12-16: Good boundary testing approach.Testing the boundary values (0 and 100) is a good practice to ensure the function works correctly at the edges of its acceptable range.
24-28: Proper error handling validation for values exceeding maximum.The tests correctly verify that the function throws an appropriate error when 'a' exceeds 100.
30-35: Good validation of second parameter flexibility.The tests verify that parameter 'b' can accept any value, including negative numbers and zero, which confirms the function's flexibility as intended.
18-22:β Verification successful
Proper error handling validation for negative inputs.
The tests correctly verify that the function throws an appropriate error when given negative values for parameter 'a'.

#!/bin/bash # Check if the sum.ts file implements the error handling as expected rg -A 10 "function sum" ./src/sum.tsLength of output: 176
Review Approved: Negative Input Error Handling Is Validated
The test in
src/sum.test.tscorrectly verifies that thesumfunction throws the expected error message when the first parameter is negative. The implementation insrc/sum.tsconfirms this by checking fora < 0(as well asa > 100) and throwing the error"0~100 μ¬μ΄μ κ°μ μ λ ₯ν΄μ£ΌμΈμ."accordingly.
37-41:β Verification successful
Verify the floating-point handling behavior.
Line 39 suggests that the
sumfunction might be implicitly rounding or truncating the result (10.5 + 20.5 = 31 instead of 31.0). Line 40 correctly usestoBeCloseTofor floating-point comparison to handle precision issues.Confirm whether this rounding behavior is intentional in the implementation.

#!/bin/bash # Check how the sum function handles floating point numbers rg -A 15 "function sum" ./src/sum.tsLength of output: 176
Floating-Point Behavior Verified in
sumFunctionAfter reviewing the implementation in
src/sum.ts, thesumfunction simply returnsa + bwithout any rounding or truncation. This means:
- For inputs like
10.5and20.5: JavaScript accurately computes the sum as31(an exact integer), which validates the test expectation usingtoBe(31).- For cases with inherent floating-point imprecision (e.g.,
0.1and0.2): The use oftoBeCloseTo(0.3)is appropriate to handle the minor precision error.There is no unexpected rounding behavior in the implementation, so the current tests correctly reflect JavaScript's arithmetic handling.
