Achu LumaIn the recent codebase update (8bf6fbd00d (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.
This commit migrates the unit tests for C character classification functions (isdigit(), isspace(), etc) from the legacy approach using the test-tool command `test-tool ctype` in t/helper/test-ctype.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_*()).
