Florian Albrechtskirchinger ad103e5b45 Improve unit testing (Part 1) (#3380) ... * Refactor unit test creation Add functions for creating tests and to supply test- and standard-specific build settings. Raises minimum CMake version to 3.13 in test directory. json_test_add_test_for( <file> MAIN <main> [CXX_STANDARDS <version_number>...] [FORCE]) Given a <file> unit-foo.cpp, produces test-foo_cpp<version_number> if C++ standard <version_number> is supported by the compiler and thesource file contains JSON_HAS_CPP_<version_number>. Use FORCE to create the test regardless of the file containing JSON_HAS_CPP_<version_number>. Test targets are linked against <main>. CXX_STANDARDS defaults to "11". json_test_set_test_options( all|<tests> [CXX_STANDARDS all|<args>...] [COMPILE_DEFINITIONS <args>...] [COMPILE_FEATURES <args>...] [COMPILE_OPTIONS <args>...] [LINK_LIBRARIES <args>...] [LINK_OPTIONS <args>...]) Supply test- and standard-specific build settings. Specify multiple tests using a list e.g., "test-foo;test-bar". Must be called BEFORE the test is created. * Use CMAKE_MODULE_PATH * Don't undef some macros if JSON_TEST_KEEP_MACROS is defined * Use JSON_TEST_KEEP_MACROS Incidentally enables the regression tests for #2546 and #3070. A CHECK_THROWS_WITH_AS in #3070 was disabled which is tracked in #3377 and a line in from_json(..., std_fs::path&) was marked with LCOV_EXCL_LINE. * Add three-way comparison feature test macro * Disable broken comparison if JSON_HAS_THREE_WAY_COMPARISON * Fix redefinition of inline constexpr statics Redelcaration of inline constexpr static data members in namespace scope was deprecated in C++17. Fixes -Werror=deprecated compilation failures. * Fix more test build failures due to missing noexcept * CI: update cmake_flags test to use CMake 3.13 in test directory Also change default for JSON_BuildTests option to depend on CMake version. * CI: turn *_CXXFLAGS into CMake lists * CI: use JSON_TestStandards to set CXX_STANDARD * CI: pass extra CXXFLAGS to standards tests		2022-03-24 07:54:07 +01:00
