一、gtest简介
gtest
是一个跨平台(Liunx、Mac OS X、Windows、Cygwin、Windows CE and Symbian)
的C++测试框架,有google公司发布。gtest测试框架是在不同平台上为编写C++测试而生成的。
gtest下载网站
https://github.com/google/googletest
二、gtest的编译
下载好gtest-1.7.0.zip之后解压
cd googletest
mkdir build
cmake -G Ninja ..
ninja
build/lib目录下生成libgtest.a和libgtest_main.a库
三、gtest使用
3.1、新建项目
(base) ➜ maingtest tree
.
├── CMakeLists.txt
└── main.cpp
3.2、将gtest资源放到项目中
将项目中的build/lib文件夹和googletest/include文件夹
(base) ➜ maingtest tree
.
├── CMakeLists.txt
├── include
│ └── gtest
│ ├── ...
│ ├── gtest.h
│ └── internal
│ ├── custom
│ │ ├── ...
│ │ └── gtest.h
│ ├── ...
│ └── gtest-type-util.h
├── lib
│ ├── libgtest.a
│ └── libgtest_main.a
└── main.cpp
首先修改CMakeLists.txt
cmake_minimum_required(VERSION 3.22)
project(maingtest)
set(CMAKE_CXX_STANDARD 14)
include_directories(include)
link_directories(lib)
add_executable(maingtest main.cpp)
target_link_libraries(
maingtest
libgtest.a
)
修改main.cpp
#include "gtest/gtest.h"
int add(int a,int b){
return a+b;
}
TEST(fun, add){
EXPECT_EQ(1, add(2,-1));
}
int main(int argc, char** argv){
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
在maingtest目录下
(base) ➜ maingtest mkdir build
(base) ➜ maingtest cd build
(base) ➜ build cmake -G Ninja ..
-- The C compiler identification is AppleClang 13.0.0.13000027
...
-- Build files have been written to: /Users/.../.../maingtest/build
(base) ➜ build ninja
[2/2] Linking CXX executable maingtest
(base) ➜ build ls
CMakeCache.txt CMakeFiles build.ninja cmake_install.cmake maingtest
(base) ➜ build ./maingtest
[==========] Running 1 test from 1 test suite.
[----------] Global test environment set-up.
[----------] 1 test from fun
[ RUN ] fun.add
[ OK ] fun.add (0 ms)
[----------] 1 test from fun (0 ms total)
[----------] Global test environment tear-down
[==========] 1 test from 1 test suite ran. (0 ms total)
[ PASSED ] 1 test.
可以看到成功的进行了测试并且通过了一个test单元测试。
