问题＃1

Question

我已经在网上阅读了一些相关的答案和一些文章以及官方的Google测试文档，但由于我缺乏这方面的经验，我对一些事情非常不安全并寻求指导。

我正在用c ++开始一个全新的宠物项目，我想在编写代码时编写适当的测试，遇到Google Test并决定尝试一下。

目前这是我的文件夹结构：

/
/bin
/main.cpp
/lib
/lib/db
/lib/external/googletest

我的想法是将测试和类文件放在自己的文件夹中，例如：

/lib/db/db.h
/lib/db/db.cpp
/lib/db/db.test

问题＃1

是否存在包含测试的文件的命名约定或期望？（上例中的/lib/db/db.test）

问题＃2

我运行了以下命令

cd lib / external / googletest / googletest
cmake。
使
make install
cp lib * .a / usr / local / lib
cp -r include / gtest / / usr / local / include /

看看它最终如何在/ usr / local / include / gtest中创建一系列.h文件，我希望能够#include <gtest/gtest.h>能够运行测试，我将其添加到我的主的.cpp：

TEST(Param1, Param2) {
    EXPECT_EQ(1, 1);
}

当出现以下错误时出现：

解决方案

感谢trojanfoe我修改了我的makefile看起来像这样：

CC=g++
target_folder=bin
all:
    $(CC) *.cpp -o $(target_folder)/prod
    ./bin/prod
test:
    $(CC) *.cpp -o $(target_folder)/test lib/external/googletest/googletest/libgtest.a lib/external/googletest/googletest/libgtest_main.a
    ./bin/test
clean:
    rm -f $(target_folder)/* *.o

现在它工作正常，请记住这是一个骨架项目，我需要构建测试文件和入口点，所以此时它只是编译一个基本测试。

您忘记了将google测试库与可执行文件链接在一起。

无法在OSX Yosemite上编译googletest
