c – 使用Visual Studio 2010的CATCH单元测试套件

导读：据我了解,我可以简单地将catch.hpp放入我的项目目录,将其添加到项目中,然后开始编写测试.一旦我尝试使用 tutorial中概述的一些宏,我就遇到了一些或者11个确切的链接器错误. #include "catch.hpp"unsigned int Factorial( unsigned int number ) { return num

据我了解,我可以简单地将catch.hpp放入我的项目目录,将其添加到项目中,然后开始编写测试.一旦我尝试使用
tutorial中概述的一些宏,我就遇到了一些或者11个确切的链接器错误.
#include "catch.hpp"
unsigned int Factorial( unsigned int number ) {
return number <= 1 ? number : Factorial(number-1)*number;
}
TEST_CASE( "Factorials are computed","[factorial]" ) {
REQUIRE( Factorial(1) == 1 );
REQUIRE( Factorial(2) == 2 );
REQUIRE( Factorial(3) == 6 );
REQUIRE( Factorial(10) == 3628800 );
}
我能够在第一个例子中创建一个文件并用g编译它,但是当我只是将相同的代码粘贴到我的VS2010项目中然后尝试运行它时,我遇到了链接器错误.不幸的是,我现在还不熟悉C来自己解码错误,在看了单个文件here之后,我无法辨别出这个问题.

只需扫描您提供的链接,我认为您可能需要在文件顶部添加此行.
#define CATCH_CONFIG_MAIN // This tells Catch to provide a main() - only do this in one cpp file 看起来您尝试链接的函数位于#if定义的CATCH_CONFIG_MAIN …. #endif预处理程序指令中. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
