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_*()). Mentored-by: Christian Couder Helped-by: René Scharfe Helped-by: Phillip Wood Helped-by: Taylor Blau Signed-off-by: Achu Luma --- The change between version 4 and version 5 is: - Added tests to handle EOF. Thanks to Phillip for noticing the missing tests.. Here is a diff between v4 and v5: + if (!check(!func(EOF))) \ + test_msg(" i: 0x%02x (EOF)", EOF); \ Thanks also to René, Phillip, Junio and Taylor who helped with previous versions.
