gtest单元测试简单demo

https://github.com/google/googletest

下载gtest源码编译安装

mkdir build && cd build && cmake .. && make -j4 && make install

直接make install到系统指定的用户头文件和库所在路径，方便后面直接用

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

project(Aut)

add_executable(Aut
	Aut.cpp
	../src/A.cpp)

target_include_directories(Aut PUBLIC
	"../include"
    )

target_link_libraries(Aut PUBLIC gtest_main gtest pthread)

include/A.h

class A
{
public:
	int test(void);
};

src/A.cpp

#include "A.h"
#include <cstdio>

int A::test(void)
{
	printf("normal test");
	return 0;
}

main.cpp

#include <cstdio>
#include "A.h"

int main()
{
	A a;
	int ret = a.test();
	printf("ret = %d\n");
	return 0;
}

ut/Aut.cpp

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

#include "Aut.h"

TEST(footest, test)
{
		A a;
		EXPECT_EQ(a.test(), 0);
}

ut/Aut.h

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

#include "A.h"

class footest : public testing::Test
{
	
};

ut/CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

project(Aut)

add_executable(Aut
	Aut.cpp
	../src/A.cpp)

target_include_directories(Aut PUBLIC
	"../include"
    )

target_link_libraries(Aut PUBLIC gtest_main gtest pthread)

main可以直接在外面mkdir build && cd build && cmake .. && make -j4

ut可以直接进入到ut目录下mkdir build && cd build && cmake .. && make -j4

上面就是简单的使用gtest做单元测试demo。
