How to install google test windows

Настройка рабочей среды

Установка библиотеки GTest в Ubuntu Linux

Для установки GTest в Ubuntu достаточно выполнить команду

sudo apt install libgtest-dev

Установка библиотеки GTest в Windows 10

Для установки библиотеки GTest в Windows 10 скачаем ее исходный код, скомпилируем с помощью CMake и подключим собранную библиотеку и заголовочные файлы к MinGW.

Убедитесь в том, что в системе установлены MinGW и CMake.

Скачайте zip архив со страницы релиза (версия 1.11.0 на момент написания текста). Ссылка находится в самом низу страницы.

gtest-download

Распакуйте архив и перейдите в директорию, содержащую файл CMakeLists.txt. Выполняем сборку с помощью следующих команд (используйте интерфейс PowerShell):

> mkdir build;                   # создаем директорию для сборки
> cd build;                      # переходим в директорию build
> cmake -G "MinGW Makefiles" ..  # генерируем файлы для сборки
> cmake --build .                # запускаем сборку

Подключаем библиотеку к MinGW:

  1. Скопируйте директорию googletest/include/gtest, в директорию MinGW, которая у автора этого текста выглядит так mingw32/lib/gcc/i686-w64-mingw32/8.1.0/include/.
  2. Скопируйте содержимое директории build/lib (четыре файла с расширением .a) в директорию MinGW mingw32/lib/.

Готово. Теперь Вы можете подключать библиотеку GTest к своим проектам.

A: convenient and fast installation GoogleTest

1. Open items that you need to test, right -click the project

2. Select Manage Nuget Packages

3. In the manager interface, select Browse to search for Google Test, and click Install after finding it

B: Configure the LIB path and generate command line

LIB path:$(SolutionDir)\packages\googletest.1.8.3\build\native\lib\$(PlatformTarget)\v141\$(Configuration)\
There is a macro inside, theoretically, everyone will be universal, and you can modify it according to your current situation

B: Use the command line, copy different directory, the corresponding version of the DLL to the working directory, and delete the DLL of the previous version difference
Working directory is default$(ProjectDir)

Generate an event

del "$(ProjectDir)googletest_v141.dll"

Post -generated event

xcopy /y /d "$(SolutionDir)packages\googletest.redist.1.8.3\build\native\bin\$(PlatformTarget)\v141\$(Configuration)\googletest_v141.dll" "$(ProjectDir)"

There is a macro inside, theoretically, everyone will be universal, and you can modify it according to your current situation

GTest Doc: https://google.github.io/googletest/



Example // Configure according to the above, this code can run directly (C ++ 20)

#include <iostream>

#define GTEST_LANG_CXX11 1

#pragma comment(lib, "googletest_v141.lib")

#include "gtest/gtest.h"

auto Add(auto a, auto b) -> decltype(a + b)
{
    return a + b;
}

TEST(AddTest, Float)
{
    EXPECT_EQ(Add(1.f, 2.f), 3.f);
    EXPECT_EQ(Add(3.f, 2.f), 5.f);
}

TEST(AddTest, Int)
{
    EXPECT_EQ(Add(1, 2), 3);
    EXPECT_EQ(Add(3, 2), 5);
}

int main(int argc, char** argv)
{
    testing::InitGoogleTest(&argc, argv);

    std::cout << "Hello,World!" << std::endl;

    return RUN_ALL_TESTS();
}

D: The problem that may be encountered

Nuget manager cannot find Google Test


Reason: NUGET Bag Source has only local directory
Solution: Options-> Nuget bag manager-> Baoyuan-> Add->https://api.nuget.org/v3/index.jsonorhttps://nuget.cdn.azure.cn/v3/index.json
It can be added at the same time

After the settings are completed, reopen the Nuget Manager and adjust the source

Google Test file failure


Reason: Google Test only supports abstract detection for the C ++ standard of the compiler, and there is a chance to determine whether the current compiler supports C ++ 11
Solution: #include «GTEST.H» before adding#define GTEST_LANG_CXX11 1

Application error-cannot start normally, click «OK» to close the application


Reason: Unsuccessful cleaning, copy the corresponding version DLL
Solution: Re -generate or manually delete GoogleTest_v141.dll

Congratulations! You have successfully compiled googletest on Windows using MinGW with MSYS.

Method 3: Integrating googletest with Your Project

Step 1: Download and Install MinGW with MSYS

First, you need to download and install MinGW with MSYS. You can download it from the MinGW website.

Step 2: Download and Build googletest

  1. Download the latest release of googletest from the googletest GitHub repository.
  2. Extract the downloaded file to a directory of your choice.
  3. Open MSYS and navigate to the directory where you extracted googletest.
  4. Run the following commands to build googletest:
cd googletest-master
mkdir build
cd build
cmake ..
make

Step 3: Integrate googletest with Your Project

  1. Add the include directory from the googletest source directory to your project’s include directories.
  2. Add the lib directory from the googletest build directory to your project’s library directories.
  3. Link your project with the gtest and gtest_main libraries.

Here is an example CMakeLists.txt file:

cmake_minimum_required(VERSION 3.0)

project(MyProject)

include_directories(${CMAKE_SOURCE_DIR}/googletest-master/googletest/include)

link_directories(${CMAKE_SOURCE_DIR}/googletest-master/build/lib)

add_executable(MyProject main.cpp)

target_link_libraries(MyProject gtest gtest_main)

Here is an example test file:

#include 

TEST(MyTest, Test1)
{
    EXPECT_EQ(1, 1);
}

int main(int argc, char **argv)
{
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

In this example, we have a test case named MyTest with a single test named Test1. The test expects 1 to be equal to 1. The main function initializes googletest and runs all the tests.
