CLion에서 google test를 좋은 느낌으로 돌립니다.

동기

지금의 IDE라면 표준으로 갖추고 있는 테스트 코드 실행과 결과의 시각화를 CLion에서도 하고 싶다

CUI를 사용하여 ctest(googletest 평소 산출이 없기 때문에 잘 움직이지 않을 것이라고 생각했다)

$ ctest
Test project /Users/usadamasa/workspace/cpp/sandbox
    Start 1: awesome
1/1 Test #1: awesome ..........................***Failed    0.01 sec

0% tests passed, 1 tests failed out of 1

Label Time Summary:
awesome    =   0.01 sec (1 test)
lib        =   0.01 sec (1 test)

Total Test time (real) =   0.02 sec

The following tests FAILED:
      1 - awesome (Failed)
Errors while running CTest

그래서 런타임에 -V 옵션을 붙이면 좋다.

--output-on-failure 쪽이 보기 쉽다.

숙제

디버그 빌드와 릴리스 빌드로 바이너리의 출력처를 나누고 싶었다.
아래의 설정을 함으로써,

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY
    ${CMAKE_SOURCE_DIR}/bin/${CMAKE_BUILD_TYPE}
)

cmake -DCMAKE_BUILD_TYPE=Debug .

등으로하면 가능하지만 아무것도 지정하지 않으면 ${CMAKE_BUILD_TYPE}가 비어 있기 때문에${CMAKE_SOURCE_DIR}/bin 바로 아래에 출력되어 버려, 이마이치.
디폴트 값과 같은 것을 사용할 수 있으면 좋았지만 잘 되지 않았다…

추가

이것으로 갔다.

cmake/cxx_build.cmake

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG
    ${CMAKE_SOURCE_DIR}/bin/debug
)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE
    ${CMAKE_SOURCE_DIR}/bin/release
)
