最近看了重構(gòu):改善現(xiàn)有代碼...里面的JAVA人寫了一個測試用例,吹噓用到了JAVA反射等"高級功能",我也寫一些測試代碼看看.首先是代表性能數(shù)據(jù)的類:classCapabilityCount{public:staticvoidOut();char*m_clue;CapabilityCount*m_pre;DWORDm_fr

最近看了重構(gòu):改善現(xiàn)有代碼...里面的JAVA人寫了一個測試用例,吹噓用到了JAVA反射等"高級功能",我也寫一些測試代碼看看.

首先是代表性能數(shù)據(jù)的類:

classCapabilityCount

{

public:

staticvoidOut();

char*m_clue;

CapabilityCount*m_pre;

DWORDm_frequency;

DWORDm_times;

staticCapabilityCount*head;

CapabilityCount(char*clue);

};

CapabilityCount*CapabilityCount::head=0;

CapabilityCount::CapabilityCount(char*clue)

{

m_pre=head;

head=this;

m_clue=clue;//連成一片,接受一個字符串作輸出標識.

}

voidCapabilityCount::Out()//輸出到文本文件

{

std::fstreamout;

CTimetime;

out.open("d:\\testcount.txt",std::ios_base::ate|std::ios_base::out);

ASSERT(out.is_open());

time=CTime::GetCurrentTime();

out"isbeginwritein"time.GetDay()":"

time.GetHour()":"

time.GetMinute()"\n";

CapabilityCount*psearch=head;

while(psearch)

{

out"type:"psearch-m_clue"alltime(milliseconds):"psearch-m_times

"becallfrequency:"psearch-m_frequency

"averagetime(milliseconds):"

psearch-m_times/psearch-m_frequency"\n\n";

psearch=psearch-m_pre;

}

}

然后是一個"改動者",負責(zé)更新CapabilityCount類

classCapabilityCountHelper

{

DWORDm_begintime;

CapabilityCountm_supervised;

public:

CapabilityCountHelper(CapabilityCountin);

~CapabilityCountHelper();

};

CapabilityCountHelper::CapabilityCountHelper(CapabilityCountin):

m_supervised(in)

{

m_begintime=GetTickCount();

++m_supervised.m_frequency;//被調(diào)用的次數(shù)

}

CapabilityCountHelper::~CapabilityCountHelper()

{

DWORDspend=GetTickCount()-m_begintime;

m_supervised.m_times+=spend;//花掉的總時間

}

知道怎么用吧?

在要測試的函數(shù)前加上

staticCapabilityCount//一定要有static哦

CapabilityCountInstance("functionnameorelse");

CapabilityCountHelperCapabilityCountHelperInstance(CapabilityCountInstance);

嫌麻煩?

#defineKILL_BILL__KILL_BILL__KILL_BILL(clue)staticCapabilityCount\

CapabilityCountInstance(clue);\

CapabilityCountHelperCapabilityCountHelperInstance(CapabilityCountInstance)\

最近想看殺死比爾,雖然殺的不是我想的:(

你可以用更精確的時間函數(shù)來測試.不過這不關(guān)我事;

你也可以在內(nèi)聯(lián)函數(shù)中
