These four supported configuration macros were never actually compiled anywhere in the test matrix: - JSON_NO_IO and the JSON_THROW_USER/JSON_TRY_USER/JSON_CATCH_USER trio are exercised together in a new tests/src/unit-no_io_and_user_exceptions.cpp, which is automatically picked up by the existing unit-*.cpp test glob and thus built across the whole standard test matrix. - JSON_SKIP_LIBRARY_VERSION_CHECK is exercised by a new, dedicated tests/src/skip_library_version_check.cpp, compiled directly by the new ci_test_skiplibraryversioncheck target in cmake/ci.cmake: the scenario it simulates (mixing two differently-versioned inclusions of the library) unavoidably triggers the compiler's own "macro redefined" warning, which would fail under the library's own -Weverything/-Werror unit test matrix for a reason unrelated to the macro under test. - JSON_DisableEnumSerialization already had #if-guarded tests in several unit-*.cpp files (from #4384), but no CMake target ever actually set the JSON_DisableEnumSerialization CMake option, so that guarded code was never compiled. Add ci_test_disableenumserialization, mirroring the existing ci_test_noimplicitconversions/ci_test_noglobaludls targets. Building the full test suite with this option on surfaced one real, narrow gap: get<T>() on std::vector<std::byte> (used by unit-regression2.cpp's custom BinaryType tests) relies on std::byte being handled via enum serialization, so add the same #if-guard convention to the two affected SECTIONs there. Both new CI targets are added to the ci_cmake_options matrix in .github/workflows/ubuntu.yml, alongside the existing ci_test_* targets. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
