C + + Unit Test Tool Cppunit use Introduction

Preparatory work:

1. Download the source code of Cppunit test framework to http://sourceforge.net/projects/cppunit/

2. Extract files, enter the SRC folder, open cppunitlibraries.dsw. Compile the two project separately, the output location is the Lib folder.

3. Set include path and Lib path in VC tools/options/directories/include files and library files.

4. Right key My Computer settings-> advanced-> environment variable-> system variable->path, set the Cppuint directory's LIB path to the system search path

To create a test project:

1. Open VC new Project based on MFC dialog box, add in StdAfx.h

#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.修改对话框初始化函数
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( );
};

In the CPP file

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);
}
