From d30aca3eeffc18452e5cc5c4e59f1a4da2bd2f12 Mon Sep 17 00:00:00 2001 From: Ryota Sakamoto Date: Sun, 21 Dec 2025 13:35:16 +0000 Subject: lib/tests: convert test_min_heap module to KUnit Move lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it to use KUnit. This change switches the ad-hoc test code to standard KUnit test cases. The test data remains the same, but the verification logic is updated to use KUNIT_EXPECT_* macros. Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is no longer used. The new CONFIG_MIN_HEAP_KUNIT_TEST will be automatically enabled by CONFIG_KUNIT_ALL_TESTS. The reasons for converting to KUnit are: 1. Standardization: Switching from ad-hoc printk-based reporting to the standard KTAP format makes it easier for CI systems to parse and report test results 2. Better Diagnostics: Using KUNIT_EXPECT_* macros automatically provides detailed diagnostics on failure. 3. Tooling Integration: It allows the test to be managed and executed using standard KUnit tools.
