Google Test 未找到任何测试

问题描述 投票：0回答：4

所以我正在创建我的第一个单元测试。我正在使用 Google Test，该版本当前内置于 Visual Studio 2017 中。这是概念验证的尝试，非常简单。

我在测试代码的解决方案中有一个项目：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);
}

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;
}

一切都编译得很好，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，我不确定为什么。

常见情况下的 GoogleTest 框架 requires 

RUN_ALL_TESTS
中的宏 
main
:

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

然后您可以将测试添加到不同的

cpp
文件中，幕后的魔法将启动所有测试并显示漂亮的报告。

尽管如此，即使没有这个宏，您也可以使用 Google 测试。请参阅此答案。

我知道这个线程很旧，但我发现了导致此错误的另一个潜在原因。就我而言，测试 exe 文件无法加载 DLL，并且在未提供测试列表的情况下终止。我在项目设置中将测试单元的输出目录更改为与 DLL 相同，之后测试工作正常。

@NuPagadi 他的答案是对的。如果之后仍然有问题，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 并测试资源管理器找到所有测试。

RUN_ALL_TESTS()
中关于
main
的答案很接近，但不一定能准确指出预期的解决方案。
目前无需手动即可进行发现工作 
main()
。

首先，在 Tools -> Options -> Test Adapter for Google Test -> General -> Print Debug Info 下启用调试可能很有用。

在那里有一个条目

Found X test method symbols and 0 trait symbols in binary
。
一个实际的问题是在 Linker -> Additional Dependency 中包含通配符 *\*.obj （目的是避免手动添加每个 .obj），它意外地将 obj 与引用项目中的 main() 一起使用，这以某种方式阻止了 Google 测试的预期主要内容。
删除多余的 *.obj 解决了问题。
