How to configure clion to use googletest for testing on mac

1. Download googletest and compile

wget https://github.com/google/googletest/archive/release-1.8.0.tar.gz && \
tar zxf release-1.8.0.tar.gz && \
rm -f release-1.8.0.tar.gz && \
cd googletest-release-1.8.0 && \
cmake configure . && \
make && \
make install

Or 1. If you want to have googletest directly in the project, copy the downloaded googletest to our project directory

2. Create a new project using cloin

3. Modify CMakeList.txt

cmake_minimum_required(VERSION 3.9)
project(tennis_status)

set(CMAKE_CXX_STANDARD 17)

add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} gtest)

Or 3. When using googletest under your own project, modify CMakeLists.txt

cmake_minimum_required(VERSION 3.9)
project(tennis)

set(CMAKE_CXX_STANDARD 17)

add_subdirectory(./googletest)
set(LIBRARIES
        gtest
        pthread)

add_executable(tennis main.cpp)
target_link_libraries(tennis ${LIBRARIES})

4. Start trying to write your first unit test

#include <iostream>
#include <gtest/gtest.h>

int add(int a, int b) {
    return a + b;
}

TEST(test, c1) {
    EXPECT_EQ(3, add(1, 2));
}

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

After everything is configured, you should see an execute button in the cloin

5. Click the execute button to execute successfully
