c++ - Setup Google test in CLion

Question

I have been sitting online for hours already trying to setup Google test on Clion in Linux but have not been able to find anything.

Can someone guide me with setting this up please?

Answer 1

Create new Project

1. Create a repository in my ClionProjects folder
   • cd ~/ClionProjects
   • mkdir .repo
   • cd .repo
2. Clone the DownloadProject from github
   • git clone https://github.com/Crascit/DownloadProject.git
3. Create a C++ project with a src and test directory

Add following files:

CMakeLists.txt

cmake_minimum_required(VERSION 3.3)

project(MyProjectName)

add_subdirectory(src)
add_subdirectory(test)

src/CMakeLists.txt

#set(core_SRCS ADD ALL SOURCE FILES HERE)

add_library(core ${core_SRCS})
add_executable(exe main.cpp)
target_link_libraries(exe core)

[We compile a library so we can include it inside the Test project]

test/CMakeLists.txt

cmake_minimum_required(VERSION 3.3)

set(REPO ~/ClionProjects/.repo)

project(Test)

project(Example)

include(CTest)
enable_testing()

#set(gtest_disable_pthreads on) #needed in MinGW
include(${REPO}/DownloadProject/DownloadProject.cmake)
download_project(
        PROJ                googletest
        GIT_REPOSITORY      https://github.com/google/googletest.git
        GIT_TAG             master
        UPDATE_DISCONNECTED 1
        )

add_subdirectory(${googletest_SOURCE_DIR} ${googletest_BINARY_DIR} EXCLUDE_FROM_ALL)

#set(test_SRCS ADD ALL TEST SOURCE FILES HERE)
add_executable(runUnitTests gtest.cpp ${test_SRCS})
target_link_libraries(runUnitTests gtest gmock core)
#add_test(runUnitTests runUnitTests) #included in all tutorials but I don't know what it actually does.

test/gtest.cpp

#include "gtest/gtest.h"

int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

Note: if you work yourself on a git Project it is better to include the DownloadProject.cmake and DownloadProjects.CmakeLists.cmake.in files inside the project.
