CMake创建CTest工程

在CMake工程顶层目录内的CMakeLists.txt文件中添加最后一行，使得目录结构中包含test目录，并且编译完成时会在build目录下产生test_bin目录。

cmake_minimum_required(VERSION 2.8)
project (your_project_name)
add_subdirectory(src bin)
add_subdirectory(test test_bin)

step2

在test目录下的CMakeLists.txt文件中就像src目录下的一样配置，你需要什么库，就加在里面。不过需要一点下面的设置

include(CheckFunctionExists)
include(CheckCXXSourceCompiles)
include(CheckLibraryExists)
include(CPack)
enable_testing()

step3

test目录下创建一个main函数，里面编写测试代码，我尝试着使用boost的test框架，暂时还没有成功，因此使用了一个宏（来源于CppCMS的作者Artyom）

#ifndef CPPCMS_TEST_H
#define CPPCMS_TEST_H


#include <stdexcept>
#include <sstream>


#define TEST(X) 								\
	do {									\
		if(X) break;							\
		std::ostringstream oss;						\
		oss << "Error " << __FILE__ << ":"<<__LINE__ << " "<<#X;	\
		throw std::runtime_error(oss.str());				\
	}while(0)	


#endif

使用这个宏很简单，比如：

TEST(result >= 66);

step4
进入build目录编译,编译成功后，进入test_bin目录运行ctest,屏幕上会看到一些简要的结果信息：

Test project /home/chenshu/work/CommonService/trunk/c++/PipeLine2/build/test_bin
    Start 1: similarity_test
1/1 Test #1: similarity_test ..................***Failed    0.31 sec

0% tests passed, 1 tests failed out of 1

Total Test time (real) =   0.89 sec

The following tests FAILED:
	  1 - similarity_test (Failed)
Errors while running CTest

并且会产生Testing/Temporary/目录，该目录下包含了几个文件，CTestCostData.txt LastTest.log LastTestsFailed.log，详细测试信息都在其中。
