一、工具简介

googletest 是 Google 公司开发一款跨平台（ Linux 、 Windows 、 Mac ）测试工具。

二、依赖说明

三、编译安装

# 下载googletest源码
cd /tmp
git clone https://github.com/google/googletest
# 进入/创建编译目录
cd googletest
mkdir build
cd build
# 编译 - cmake version<=2.8 可能出现错误,见下文
cmake ../
make -j 8
# 默认安装 
make install 
执行编译后会得到四个静态库文件：
libgtest.a
libgtest_main.a
libmock.a
libmock_main.a
必要的头文件：
googltest/include/gtest
googlemock/include/gmock
手动安装过程：
拷贝静态库到自定义文件夹
拷贝头文件到自定义文件夹
默认安装（make install）：
静态库文件会被拷贝到/usr/local/lib64/
头文件会被拷贝到/usr/local/include/
说明：根据操作系统安装路径可能不同。
说明：编译后不存在运行时环境（动态库），不需要使用ldconfig加载。
四、测试程序
/* file:test.cpp */
#include <stdio.h>
#include <gtest/gtest.h>
int add(int a, int b) {
    return a+b;
TEST(MyTest, AddTest) {
    EXPECT_EQ(add(1, 2), 3);
int main(int argc, char *argv[]) {
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
g++ -o test test.cpp -std=c++11 -lgtest -lgtest_main -lpthread
# ./test 
[==========] Running 1 test from 1 test suite.

[       OK ] MyTest.AddTest (0 ms)
[----------] 1 test from MyTest (0 ms total)
[----------] Global test environment tear-down
[==========] 1 test from 1 test suite ran. (1 ms total)
[  PASSED  ] 1 test.
五、一些可能的错误和说明
5.1.cmake版本过低
cmake版本小于2.8，可能会出现如下参数错误情况：
CMake Error at googletest/CMakeLists.txt:134 (target_include_directories):
  target_include_directories called with invalid arguments
CMake Error at googletest/CMakeLists.txt:137 (target_include_directories):
  target_include_directories called with invalid arguments
CMake Error at googlemock/CMakeLists.txt:110 (target_include_directories):
  target_include_directories called with invalid arguments
CMake Error at googlemock/CMakeLists.txt:113 (target_include_directories):
