集成

CMake Head-Only

CMake FetchContent

Head-only引入的话，编译速度会慢。因此建议编译后链接。

include(FetchContent)  
FetchContent_Declare(
    doctest
    GIT_REPOSITORY https://github.com/doctest/doctest.git
    GIT_TAG v2.4.9         
    GIT_SHALLOW TRUE
)
FetchContent_MakeAvailable(doctest)  ​  

enable_testing()
add_executable(test main.cpp)
target_link_libraries(test PRIVATE doctest_with_main)

main.cpp

#include "doctest/doctest.h"

int factorial(int number) { return number <= 1 ? number : factorial(number - 1) * number; }

TEST_CASE("testing the factorial function") {
    CHECK(factorial(1) == 1);
    CHECK(factorial(2) == 2);
    CHECK(factorial(3) == 6);
    CHECK(factorial(10) == 3628800);
}
