From 4d00d948ff5796ba5a8a253eb73da5ea36a72657 Mon Sep 17 00:00:00 2001 From: Ghanshyam Thakkar Date: Mon, 20 May 2024 02:14:42 +0530 Subject: t/: port helper/test-strcmp-offset.c to unit-tests/t-strcmp-offset.c In the recent codebase update (8bf6fbd (Merge branch 'js/doc-unit-tests', 2023-12-09)), a new unit testing framework was merged, providing a standardized approach for testing C code. Prior to this update, some unit tests relied on the test helper mechanism, lacking a dedicated unit testing framework. It's more natural to perform these unit tests using the new unit test framework. Let's migrate the unit tests for strcmp-offset functionality from the legacy approach using the test-tool command `test-tool strcmp-offset` in helper/test-strcmp-offset.c to the new unit testing framework (t/unit-tests/test-lib.h). The migration involves refactoring the tests to utilize the testing macros provided by the framework (TEST() and check_*()).
