C++单元测试工具CppUnit利用简介[VC/C++编程]

预备工作:

1. 到 http://sourceforge.net/projects/cppunit/下载CppUnit测试框架的源代码

2. 解压文件,进入src文件夹,翻开CppUnitLibraries.dsw.辨别编译这两个project,输出位置均为lib文件夹.

3.在VC的tools/options/directories/include files和library files中设置include途径和lib途径.

4.右键我的电脑设定->高级->环境变量->系统变量->Path中,将Cppuint的目录的lib途径设置为系统搜索途径

成立测试工程:

1.翻开VC新建基于MFC对话框的Project,在stdafx.h中添

#include <cppunit/ui/mfc/TestRunner.h>
#include <cppunit/extensions/TestFactoryRegistry.h>
#include <cppunit/extensions/HelperMacros.h>
#ifdef _DEBUG
　　#pragma comment( lib, "testrunnerd.lib" )
　　#pragma comment( lib, "CppUnitd.lib" )
#else
　　#pragma comment( lib, "testrunner.lib" )
　　#pragma comment( lib, "CppUnit.lib" )
#endif
using namespace CppUnit;

2.改正对话框初始化函数
CUnitTestApp::InitInstance()
{
MfcUi::TestRunner runner;
runner.addTest( TestFactoryRegistry::getRegistry("SamepleUnitTest").makeTest() );
runner.run(); //show UI

/*
CUnitTestDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{......}
*/
}

3.将要测试的project加入到本project中,实现测试用例类
class CSamepleTestCase : public TestCase
{
public:
　CSamepleTestCase(void);
　virtual ~CSamepleTestCase(void);

　CPPUNIT_TEST_SUITE(CSamepleTestCase);
　CPPUNIT_TEST( TestAdd );
　CPPUNIT_TEST_SUITE_END();
　VOID TestAdd( );
};

在CPP文件中

CPPUNIT_TEST_SUITE_NAMED_REGISTRATION（ CSamepleTestCase,"SamepleUnitTest" ）;

#include <另一个工程中的头文件>
void CSamepleTestCase::TestAdd( void )
{
　//在这里写测试用例
　CPPUNIT_ASSERT_EQUAL( 1, 1);
}
