谷歌测试没有找到任何测试答案

【问题描述】：

所以我正在努力创建我的第一个单元测试。我正在使用 Google Test，这是目前内置于 Visual Studio 2017 中的版本。这是对概念验证的尝试，非常简单。

我在解决方案中有一个项目为测试代码：test.cpp

#include "pch.h"
#include "../ConsoleApplication1/ConsoleApplication1.cpp"

TEST(SumTest, FirstTest) {
  EXPECT_EQ(6, sum(2, 4));
}

TEST(SumTest, SecondTest) {
    EXPECT_EQ(1, 1);
    EXPECT_TRUE(true);
}

而且我有一个简单的方法可以在 ConsoleApplication1.cpp 中进行测试

// ConsoleApplication1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

int sum(int a, int b);

int main()
{
    int x = sum(2, 4);
    printf("The answer is: %d \n", x);

}

int sum(int a, int b) {
    return a + b;
}

一切编译正常，但是当我从测试资源管理器菜单中单击“全部运行”时，我得到以下输出：

它似乎没有发现我编写的任何一个测试，我不知道为什么。

【问题讨论】：

看来您应该将RUN_ALL_TESTS 添加到您的main 中。查看示例github.com/google/googletest/blob/master/googletest/docs/…
您不应包含 *.cpp 文件，如：#include "../ConsoleApplication1/ConsoleApplication1.cpp。其次，为了能够使用gtest，您需要包含它（它是否包含在“pch.h”中？）。第三，gtest 有一种特殊的初始化和执行方式。查看文档
@NuPagadi 这就是我所需要的！
@Amadeus 看起来这只是我缺少的初始化。 Gtest 包含在 pch.h 为什么包含 #.cpp 是一种不好的做法？
@NeilRuggiero 我就不赘述了，你可以看这里，例如：stackoverflow.com/questions/1686204/… 对了，为什么gtest.h会埋在pch.h中？

【解决方案1】：

普通情况下的GoogleTest框架requiresRUN_ALL_TESTSmain中的宏：

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

然后您可以将您的测试添加到不同的cpp 文件中，后台的魔法将启动所有测试并显示漂亮的报告。

不过，即使没有此宏，您也可以使用 Google 测试。看到这个answer。

【讨论】：

非常感谢，这解决了我的问题。接受你的回答。
那个链接失效了
我也有同样的问题。应该在哪里添加 RUN_ALL_TESTS？在 test.cpp 还是 ConsoleApplication1.cpp 中？
@Hamid，在 test.cpp 中。库中没有主函数，如果你要测试它。
@NuPagadi 我有同样的问题。但是，如果我在测试项目中添加 main 函数，它会抱怨 main 已经定义了两次。这显然是这种情况，因为我的 main.cpp（实际项目的一部分）中已经有一个 main 函数。在该项目中不包含测试框架（因此我无权访问标题以将其包含在其中）请帮助？

【解决方案2】：

@NuPagadi 有权使用他的answer。如果您之后仍然有问题，请使用正确的 google test nuget。我有相同的代码，我只是从dyn.rt-dyn 切换到static.rt-dyn 和测试资源管理器找到所有测试。
