From ad103e5b454a7e9ae2170d2cfdba5aa60979c9cd Mon Sep 17 00:00:00 2001 From: Florian Albrechtskirchinger Date: Thu, 24 Mar 2022 07:54:07 +0100 Subject: [PATCH] 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( MAIN
[CXX_STANDARDS ...] [FORCE]) Given a unit-foo.cpp, produces test-foo_cpp if C++ standard is supported by the compiler and thesource file contains JSON_HAS_CPP_. Use FORCE to create the test regardless of the file containing JSON_HAS_CPP_. Test targets are linked against
. CXX_STANDARDS defaults to "11". json_test_set_test_options( all| [CXX_STANDARDS all|...] [COMPILE_DEFINITIONS ...] [COMPILE_FEATURES ...] [COMPILE_OPTIONS ...] [LINK_LIBRARIES ...] [LINK_OPTIONS ...]) 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 --- .github/workflows/macos.yml | 2 +- CMakeLists.txt | 11 +- benchmarks/CMakeLists.txt | 2 +- cmake/ci.cmake | 703 +++++++++--------- cmake/test.cmake | 204 +++++ .../nlohmann/detail/conversions/from_json.hpp | 3 +- include/nlohmann/detail/macro_scope.hpp | 9 + include/nlohmann/detail/macro_unscope.hpp | 20 +- include/nlohmann/detail/meta/cpp_future.hpp | 8 +- single_include/nlohmann/json.hpp | 40 +- test/CMakeLists.txt | 232 +++--- test/src/unit-alt-string.cpp | 6 +- test/src/unit-cbor.cpp | 2 +- test/src/unit-class_parser.cpp | 28 +- test/src/unit-comparison.cpp | 6 +- test/src/unit-conversions.cpp | 7 - test/src/unit-items.cpp | 7 - test/src/unit-regression1.cpp | 4 - test/src/unit-regression2.cpp | 67 +- test/src/unit-ubjson.cpp | 4 +- 20 files changed, 757 insertions(+), 608 deletions(-) create mode 100644 cmake/test.cmake diff --git a/.github/workflows/macos.yml b/.github/workflows/macos.yml index 6a378f13f1..d01502bf5d 100644 --- a/.github/workflows/macos.yml +++ b/.github/workflows/macos.yml @@ -38,7 +38,7 @@ jobs: steps: - uses: actions/checkout@v2 - name: cmake - run: cmake -S . -B build -D CMAKE_BUILD_TYPE=Debug -DJSON_BuildTests=On -DCMAKE_CXX_STANDARD=${{ matrix.standard }} -DCMAKE_CXX_STANDARD_REQUIRED=ON + run: cmake -S . -B build -D CMAKE_BUILD_TYPE=Debug -DJSON_BuildTests=On -DJSON_TestStandards=${{ matrix.standard }} - name: build run: cmake --build build --parallel 10 - name: test diff --git a/CMakeLists.txt b/CMakeLists.txt index b93c6e47fa..68bba9cf43 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -19,6 +19,7 @@ endif() ## INCLUDE ## ## +set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake ${CMAKE_MODULE_PATH}) include(ExternalProject) ## @@ -30,7 +31,13 @@ if (POLICY CMP0077) cmake_policy(SET CMP0077 NEW) endif () -option(JSON_BuildTests "Build the unit tests when BUILD_TESTING is enabled." ${MAIN_PROJECT}) +# VERSION_GREATER_EQUAL is not available in CMake 3.1 +if(${MAIN_PROJECT} AND (${CMAKE_VERSION} VERSION_EQUAL 3.13 OR ${CMAKE_VERSION} VERSION_GREATER 3.13)) + set(JSON_BuildTests_INIT ON) +else() + set(JSON_BuildTests_INIT OFF) +endif() +option(JSON_BuildTests "Build the unit tests when BUILD_TESTING is enabled." ${JSON_BuildTests_INIT}) option(JSON_CI "Enable CI build targets."
