在VS2010 C ++中使用CppUnit进行单元测试多类

问题描述

大家好，

我在VS 2010上用C ++编写了一个程序，现在我准备使用CppUnit编写UnitTest(UT).我想将每个类的UT分别编写为类，并在主函数中调用UT.
例如:我有班:A(具有功能:A1，A2，A3，A4)，
B(具有功能:B1，B2，B3)，
C(具有功能:C1，C2，C3，C4)
因此，我将有3个UT类，并且将在主函数中调用3UT类.

我知道，如果只在一个类中编写UT，那很容易，而且我可以做到.但我的要求要有3个班级.所以我遇到了困难.

希望我能得到您的帮助.

在此先感谢

Hi all,

I wrote a program by C++ on VS 2010, and now I prepare to write UnitTest(UT) using CppUnit. I want to UT of each class is written to separately classes and that UTs is called in a main function.
EX: i have classes : A(with function: A1,A2,A3,A4),
B(with function: B1,B2,B3),
C(with function: C1,C2,C3,C4)
So I will have 3 UT class and 3UT class will be called in a main function.

I know that if I write UTs in a only class, it is easy and I can do it. But my requirement want to have 3 class. So I am meeting difficult with this.

I hope that I will receive your help.

Thanks in advance

推荐答案

#define ASSERT_THAT(expr) \
    if(!(expr)) error_to_console( #expr, __FILE__, __LINE__ );

其中，error_to_console实现为:

void error_to_console(  const std::string &error_message,
			const std::string &file_name,
			long  line_no )
{
	std::cerr << file_name << "(" << line_no << ") : error : "
			  << error_message << std::endl;
}

然后您可以编写如下测试:

Then you can write tests like:

void require_string_to_implement_equality()
{
    ASSERT_THAT( std::string( "ABC" ) == std::string( "ABC" ) );
}

在我看来，这比搞CppUnit测试用例，测试和固定装置要容易得多.

值得探索其他单元测试框架. CppUnit的原始作者Michael Feathers开发了一个较小的，较简单的框架，称为 CppUnitLite [ ^ ].坦率地说，这可能会完成您想开始的所有事情，而没有任何实际的文档.但是该代码很容易阅读，并且网络上有很多示例.

which to my mind is a lot easier than messing about with CppUnit test cases, tests and fixtures.

It''s worth searching out other unit testing frameworks. Michael Feathers, the original author of CppUnit, developed a smaller, less complicated framework called CppUnitLite[^]. This probably does everything you want to start out, admittedly without any real documentation. However the code''s easy enough to read AND there are plenty of examples on the web.
