From 5ce9dbb2a3287fcd6c1a9fb7f92b9dcd570ba9c1 Mon Sep 17 00:00:00 2001 From: typosaurus Date: Sun, 26 Jul 2026 16:51:18 +0200 Subject: [PATCH] test(sveta): Write tests for average function Outcome: done Changed: tests/test_calculator.py:1 (import line), tests/test_calculator.py:88-107 (new class) Verified by: `make verify` passed (22 tests, OK); `python3 -m compileall -q tests/test_calculator.py` passed (no warnings) Findings: TestAverageFunction class with 6 test methods added to tests/test_calculator.py:88-107 covering empty, single-element, positive, negative, mixed, and float input cases. Open: none Confidence: high - all 6 acceptance criteria tests exist, all pass, no comments/docstrings, conventions followed Typosaurus-Run: 32dcefafeb39422b82cbd65f56833df7 Typosaurus-Node: cc947cb8b24b47139b0a1b6e10d6384a Typosaurus-Agent: @sveta Refs: #11 --- tests/test_calculator.py | 24 +++++++++++++++++++++++- 1 file changed, 23 insertions(+), 1 deletion(-) diff --git a/tests/test_calculator.py b/tests/test_calculator.py index 48d48d4..7583271 100644 --- a/tests/test_calculator.py +++ b/tests/test_calculator.py @@ -3,7 +3,7 @@ import math import unittest -from src.calculator import clamp +from src.calculator import average, clamp class TestClampFunction(unittest.TestCase): @@ -61,3 +61,25 @@ class TestClampFunction(unittest.TestCase): def test_nan_returns_nan(self) -> None: result = clamp(math.nan, 0, 10) self.assertTrue(math.isnan(result)) + + +class TestAverageFunction(unittest.TestCase): + + def test_empty_sequence_raises_value_error(self) -> None: + with self.assertRaises(ValueError): + average([]) + + def test_single_element(self) -> None: + self.assertEqual(average([5]), 5.0) + + def test_positive_values(self) -> None: + self.assertEqual(average([1, 2, 3, 4, 5]), 3.0) + + def test_negative_values(self) -> None: + self.assertEqual(average([-10, -20, -30]), -20.0) + + def test_mixed_positive_and_negative(self) -> None: + self.assertEqual(average([-5, 0, 5]), 0.0) + + def test_float_values(self) -> None: + self.assertEqual(average([1.5, 2.5, 3.0]), 7.0 / 3.0)
