cd googletest
makedir build && cd build
cmake -DCMAKE_CXX_STANDARD=17 ..
make
sudo make install


######test
mkdir gtestDemo
vi CMakeList.txt

echo “export CPLUS_INCLUDE_PATH=/usr/local/include" >> ~/.zshrc  

echo "export LIBRARY_PATH=/usr/local/lib" >> ~/.zshrc  
source ~/.zshrc #tell terminal there are new variables  

#CMakeList.txt
cmake_minimum_required(VERSION 3.0)
set(CMAKE_CXX_STANDARD 17)
project(demo)
find_package(GTEST REQUIRED)
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} ${GTEST_LIBRARIES})

#main.cpp
#include <iostream>
#include <gtest/gtest.h>
int add(int a, int b) {
    return a + b;
}
int sub(int a, int b) {
    return a - b;
}
// case1
TEST(test, c1) {
    EXPECT_EQ(3, add(1, 2));
    EXPECT_EQ(12, add(2, 6));
}
// case2
TEST(test, c2) {
    EXPECT_EQ(-1, sub(1, 2));
}
GTEST_API_ int main(int argc, char ** argv) {
    testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

cmake .
make
./demo

#you can also use the g++ command
g++ -std=c++11 -stdlib=libc++ main.cpp -o main

Xcode 中的使用
