first demo for gtest

first demo for gtest

1.  首先给出第一个运用gtest的demo

#include  " stdafx.h "
#include  " gmock/gmock-actions.h "

using   namespace  testing;

class  Calculate
{
public:
    Calculate(){}
    long add(long a,long b){return a+b;}
} ;

class  CalculateMock: public  Calculate
{
public:
    CalculateMock():Calculate(){}
    MOCK_METHOD2(add,long(long a,long b));
} ;

long  testFun(Calculate &  cal)
{
    return cal.add(2,3);
}
TEST(testMock,testAdd)
{
    CalculateMock obj;
    long len = 10;
    ON_CALL(obj,add(2,3)).WillByDefault(Return(len)); 
    EXPECT_CALL(obj,add(2,3)).Times(1);
    //obj.add(2,3);
    EXPECT_EQ(10, obj.add(2,3));
}

int  _tmain( int  argc, _TCHAR *  argv[])
{
    testing::InitGoogleMock(&argc, argv);  
    RUN_ALL_TESTS();
    return 0;
}

做第一个demo需要注意的事项：
1. 将用到的gtest,gmock,和你自己运用的project用同样的code generation 的形式一致,将 project property->C++->Code Generation: 设置为：Multi-threaded Debug(/MTd)
2. 添加 using namespace testing, 否则会出现‘Return’Identifier not found.这样的错误

So excited to make it work after so much confusion, anxiety.
Fighting!!
