c++ - Visual C++ 测试开箱即用项目中的错误

转载作者：行者123 更新时间：2023-11-28 20:13:06

我正在尝试将单元测试添加到 native C++ MFC 应用程序，但遇到了一些问题。我想将我的测试添加到我的主应用程序所在的同一个项目(这是一个 EXE)。

为了找出我的问题，我尽量保持干净:

我的项目，如果你想一起玩:https://drive.google.com/open?id=1ru6VU8_dBwiDHUdH_838QxHH4-oQyneG

1) 全新安装 Visual Studio 2019。我为支持 MFC 的 C++ 桌面开发进行了设置。我没有安装 Google Test 或 Boost Test 适配器。

2) 创建一个新项目，选择MFC App(我的真实应用是)

一切都在 Debug/x86(32 位)中完成

3) 按照这些说明操作:https://learn.microsoft.com/en-us/visualstudio/test/how-to-use-microsoft-test-framework-for-cpp?view=vs-2019

4) 添加了包含目录:$(VCInstallDir)Auxiliary\VS\UnitTest\include

5) 添加库目录:$(VCInstallDir)Auxiliary\VS\UnitTest\lib

6) 向项目添加了新的 C++ 文件，使用的示例来自:https://learn.microsoft.com/en-us/visualstudio/test/microsoft-visualstudio-testtools-cppunittestframework-api-reference?view=vs-2019#Initialize_and_cleanup

#include "pch.h"
#include <CppUnitTest.h>

using namespace Microsoft::VisualStudio::CppUnitTestFramework;

BEGIN_TEST_MODULE_ATTRIBUTE()
TEST_MODULE_ATTRIBUTE(L"Date", L"2010/6/12")
END_TEST_MODULE_ATTRIBUTE()

TEST_MODULE_INITIALIZE(ModuleInitialize)
{
    Logger::WriteMessage(L"In Module Initialize");
}

TEST_MODULE_CLEANUP(ModuleCleanup)
{
    Logger::WriteMessage(L"In Module Cleanup");
}

TEST_CLASS(Class1)
{

public:

    Class1()
    {
        Logger::WriteMessage(L"In Class1");
    }

    ~Class1()
    {
        Logger::WriteMessage(L"In ~Class1");
    }

    TEST_CLASS_INITIALIZE(ClassInitialize)
    {
        Logger::WriteMessage(L"In Class Initialize");
    }

    TEST_CLASS_CLEANUP(ClassCleanup)
    {
        Logger::WriteMessage(L"In Class Cleanup");
    }

    BEGIN_TEST_METHOD_ATTRIBUTE(Method1)
        TEST_OWNER(L"OwnerName")
        TEST_PRIORITY(1)
        END_TEST_METHOD_ATTRIBUTE()

    TEST_METHOD(Method1)
    {
        Logger::WriteMessage(L"In Method1");
        Assert::AreEqual(0, 0);
    }

    TEST_METHOD(Method2)
    {
        Assert::Fail(L"Fail");
    }
};

7) 解决方案构建成功。

8) 测试资源管理器显示 2 个测试。我运行所有，都失败了。错误似乎在调用 Logger::WriteMessage 的 ModuleInitialize() 中

[7/23/2019 1:27:39 PM Error] Exception Code: C0000005
    at ModuleCleanup() in C:\Work\Testing\MSUnitTestTest\MSUnitTestTest\MyTests.cpp:line 17

有趣的是，这表明它在 ModuleCleanup 中，但单击红色圆圈/白色 X 时显示的错误消息是 ModuleInitialize。此外，如果我调试测试，调用堆栈在 ModuleInitialize 下。

9) 如果我进入 Tools > Options > Test > General 并将 Logging Level 更改为 Diagnostic，我将得到以下输出:

10) 由于崩溃似乎发生在 Logger::WriteMessage 中，因此我注释掉了对 Logger::WriteMessage 的所有调用并重试。仍然崩溃，这次是在调用 IsDebuggerAttached 的 TestClassImpl::CrtHandlersSetter 中。日志包含:

我在各种排列中花了很多时间。我真的更愿意将测试代码保留在主项目中，因为这是一个遗留应用程序，我遇到了 include/linker hell 试图在一个单独的测试项目中执行它。如果必须这样做，我会这样做，但微软表示他们支持将测试保留在 exe 的项目中。

我真的不关心使用 MSTest 还是 Google Test，我只想要一些有用的东西，这样我就可以开始实际的测试编写了。

帮助!

最佳答案

Microsoft 建议的解决方法是将项目从 exe 更改为 dll，此时测试有效。作为临时解决方法，这对我来说确实有效。

我已经使用#ifdef _WINDLL 宏来确定我们是在构建 exe 还是 dll，并适本地隐藏测试代码。

希望他们会在未来的 Visual Studio 更新中为 exe 修复此问题。
