c++ - 谷歌测试没有找到任何测试

Question

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，该版本目前内置于 Visual Studio 2017 中。这是对概念验证的一次尝试，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);
}

我在 ConsoleApplication1.cpp 中有一个简单的测试方法

// 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。

Answer 1

常见案例中的GoogleTest框架requires main 中的 RUN_ALL_TESTS 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，引擎盖下的魔法将启动所有这些并显示漂亮的报告。

不过，即使没有这个宏，您也可以使用 Google Tests。看这个answer .
