cppUnit 讲解和例子

http://cppunit.sourceforge.net/doc/lastest/cppunit_cookbook.html

 

-------------------------------------UI格式 开始--------------------------------------------------------------------------------

测试代码框架：

.h

#include <cppunit/TestCase.h>
#include <CppUnit/extensions/HelperMacros.h>
#include <cppunit/extensions/TestFactoryRegistry.h>

class CPlusTestCase: public CppUnit::TestCase
{
 CPPUNIT_TEST_SUITE(CPlusTestCase);
 CPPUNIT_TEST(testAdd);
 CPPUNIT_TEST_SUITE_END();

public:
 CPlusTestCase();
 virtual ~CPlusTestCase();
 void testAdd();

 static CppUnit::Test* GetSuite();
};

 

.cpp:

#include "stdafx.h"
#include "UnitTest.h"
#include "PlusTestCase.h"
//#include <cppunit/TestAssert.h>
#include "CPlusTestSuit/Plus.h"
#include <cppunit/extensions/TestFactoryRegistry.h>

CPPUNIT_TEST_SUITE_NAMED_REGISTRATION(CPlusTestCase, "CPlusTestSuit");

CppUnit::Test* CPlusTestCase::GetSuite()
{
 CppUnit::TestFactoryRegistry& reg = CppUnit::TestFactoryRegistry::getRegistry("CPlusTestSuit");
 return reg.makeTest();
}

void CPlusTestCase::testAdd()
{
 CPlus plus;
 int nResult = plus.Add(10, 20); //执行Add操作
 CPPUNIT_ASSERT_EQUAL(30, nResult); //检查结果是否等于30
}

 

工程dll接口代码

 // Plus.h
 class AFX_EXT_CLASS CPlus
  {
 public:
  CPlus();
  virtual ~CPlus();

 public:
  int Add(int nNum1, int nNum2);
 };

 

运行测试：

 CppUnit::MfcUi::TestRunner  runner;
 runner.addTest(CPlusTestCase::GetSuite());//添加测试
 runner.run();
