Catch2

Try it in 3 steps

1. 1

   Pin Catch2 v3.16.0 with CMake FetchContent

   Declare the release tag in CMakeLists.txt, call FetchContent_MakeAvailable(Catch2), and link the test target to Catch2::Catch2WithMain.

   FetchContent_Declare(Catch2 GIT_REPOSITORY https://github.com/catchorg/Catch2.git GIT_TAG v3.16.0)Copy
2. 2

   Create a minimal TEST_CASE

   Save this as test.cpp to exercise a normal C++ boolean expression with REQUIRE.

   #include <catch2/catch_test_macros.hpp>\nTEST_CASE("addition") { REQUIRE(1 + 1 == 2); }Copy
3. 3

   Build and run through CTest

   Configure include(CTest), add Catch2's extras directory to CMAKE_MODULE_PATH, include Catch, and call catch_discover_tests(tests) first.

   cmake -S . -B build && cmake --build build && ctest --test-dir build --output-on-failureCopy
