    A source library xPack with Google Test

    This project provides the Google Test source libraries as an xPack dependency.

    The project is hosted on GitHub as xpack-3rd-party/googletest-xpack.

    Maintainer info

    This page is addressed to developers who plan to include this package into their own projects.

    For maintainer infos, please see the README-MAINTAINER file.


    As a source library xPacks, the easiest way to add it to a project is via xpm, but it can also be used as any Git project, for example as a submodule.


    A recent xpm, which is a portable Node.js command line application.

    For details please follow the instructions in the install page.


    This package is available from as @xpack-3rd-party/googletest from the registry:

    cd my-project
    xpm init # Unless a package.json is already present
    xpm install @xpack-3rd-party/googletest@latest

    Git submodule

    If, for any reason, xpm is not available, the next recommended solution is to link it as a Git submodule below an xpacks folder.

    cd my-project
    git init # Unless already a Git project
    mkdir -p xpacks
    git submodule add \


    There are three active branches:

    • master, follows the original Arm master
    • xpack, with the latest stable version (default)
    • xpack-develop, with the current development version

    All development is done in the xpack-develop branch, and contributions via Pull Requests should be directed to this branch. (Only contributions related to the xPack integration are accepted, functional contributions should be addressed to the upstream project.)

    When new releases are published, the xpack-develop branch is merged into xpack.

    Developer info


    This package provides the full Google Test & Mock code, and the configuration files required to integrate it into CMake and meson projects, by building a static library.

    Build & integration info

    The project is written in C++, and is quite large. It can be built on top of an Arm semihosting environment, but it takes about 400-500KB of code space.

    Include folders

    The following folders should be used during the build:

    • googletest/include
    • googlemock/include

    The header files can then be included in user projects with statements like:

    #include "gtest/gtest.h"
    #include "gmock/gmock.h"

    Source folders

    • googletest
    • googlemock

    The source file to be added to user projects are:

    • googletest/src/
    • googlemock/src/

    Preprocessor definitions

    There are several proprocessor definitions used to configure the build.

    For embedded platfroms, use:

    • -D_POSIX_C_SOURCE=200809L

    This will disable treading support in GTest and enable POSIX support in newlib.

    Compiler options

    • -std=c++17 or higher for C++ sources
    • -std=c11 for C sources

    C++ Namespaces

    • testing

    C++ Classes

    The project includes many classes; see the documentation for details.


    To integrate the Google Test source library into a CMake application, add this folder to the build:


    The result is a static library that can be added as an application dependency with:

    target_link_libraries(your-target PRIVATE


    To integrate the Google Test source library into a meson application, add this folder to the build:


    The result is a static library and a dependency object that can be added as an application dependency with:

    exe = executable(
      c_args: xpack_3rd_party_googletest_dependency_c_args,
      cpp_args: xpack_3rd_party_googletest_dependency_cpp_args,
      dependencies: [
      link_with: [


    A simple example showing how to use the Google Test framework is presented below and is also available in tests/src/sample-test.cpp.

    #include "gtest/gtest.h"
    static int
    compute_one (void)
      return 1;
    static const char*
    compute_aaa (void)
      return "aaa";
    TEST(Suite, Case1) {
      EXPECT_EQ(1, compute_one());
      EXPECT_STREQ("aaa", compute_aaa());
    main ([[maybe_unused]] int argc, [[maybe_unused]] char* argv[])
      printf("Running main() from %s\n", __FILE__);
      testing::InitGoogleTest(&argc, argv);
      return RUN_ALL_TESTS();

    Known problems

    • none


    The project is fully tested via GitHub Actions on each push. The test platforms are GNU/Linux, macOS and Windows, the tests are compiled with GCC, clang and arm-none-eabi-gcc and run natively or via QEMU.

    There are two set of tests, one that runs on every push, with a limited number of tests, and a set that is triggered manually, usually before releases, and runs all tests on all supported platforms.

    The full set can be run manually with the following commands:

    cd ~Work/micro-test-plus-xpack.git
    xpm run install-all
    xpm run test-all

    Live at Head

    GoogleTest now follows the Abseil Live at Head philosophy. We recommend using the latest commit in the main branch in your projects.

    Documentation Updates

    Our documentation is now live on GitHub Pages at We recommend browsing the documentation on GitHub Pages rather than directly in the repository.

    Release 1.11.0

    Release 1.11.0 is now available.

    Coming Soon

    • We are planning to take a dependency on Abseil.
    • More documentation improvements are planned.

    Welcome to GoogleTest, Google's C++ test framework!

    This repository is a merger of the formerly separate GoogleTest and GoogleMock projects. These were so closely related that it makes sense to maintain and release them together.

    Getting Started

    See the GoogleTest User's Guide for documentation. We recommend starting with the GoogleTest Primer.

    More information about building GoogleTest can be found at googletest/


    • An xUnit test framework.
    • Test discovery.
    • A rich set of assertions.
    • User-defined assertions.
    • Death tests.
    • Fatal and non-fatal failures.
    • Value-parameterized tests.
    • Type-parameterized tests.
    • Various options for running the tests.
    • XML test report generation.
