1准备条件

1.1安装gcc

sudo apt-get update
sudo apt-get install g++

1.2 安装CMake

CMake必须高于3.13 ，否则会报CMake 3.13 or higher is required. You are running version 3.XX.X。

1）下载cmake-3.20.3-linux-x86_64.tar.gz

wget https://cmake.org/files/v3.20/cmake-3.20.3-linux-x86_64.tar.gz

2）解压

tar xvzf cmake-3.20.3-linux-x86_64.tar.gz

3）移动到/usr/local/cmake目录

sudo mv cmake-3.20.3-linux-x86_64 /usr/local/cmake

4）编辑环境变量文件

gedit /etc/profile

export PATH=/usr/local/cmake/bin:$PATH

source /etc/profile

5）进入cmake目录

cd /usr/local/cmake

6）查看cmake版本

cmake –version

2 建立google Test

1）到https://github.com/google/googletest获取最新版本的googletest

wget https://github.com/google/googletest/archive/refs/heads/main.zip

2）解压

unzip main.zip

3）进入googletest目录

cd /home/jerry/googletest-main/

4）在CMakeLists.txt 中加入内容

gedit CMakeLists.txt

加入

set(CMAKE_CXX_STANDARD 14)

5）运行

cmake CMakeLists.txt

生成Makefile文件

6）执行make命令

make命令，生成四个静态库：libgtest.a libgtest_main.a,libgmlck.a, libgmock_main.a

find . -name "*.a"

7)安装gmock和gtest到系统：

sudo make install
ls -l /usr/local/lib

7)执行自带测试文件

cd googletest/samples/
g++ ../src/gtest_main.cc sample1.cc sample1_unittest.cc -o test -lgtest -lgmock -lpthread -std=c++14

l../src/gtest_main.cc 主测试文件

lsample1.cc 被测试文件

lsample1_unittest.cc：测试文件

ltest 运行生成文件

lc++14中的14表示C++14标准

8) 运行测试用例

./test
Running main() from ../src/gtest_main.cc
