gtest的一个简单扩展（�q�行旉��试�Q�的实例

��夜 — Wed, 27 Aug 2008 15:34:00 GMT

上一��中对gtest�q�行了一个简单的扩展�Q�本文通过实例��试�q�介�l�这个扩展的用法�?/p>

首先实现两个Fibonacci函数�Q�然后对�q�两个函数进行测试：

Fibonacci_1�Q��用��@环实玎ͼ�

unsigned int Fibonacci_1(unsigned int n)
{
    unsigned int i;
    unsigned int f0 = 1, f1 = 1, f2;
    for (i = 1; i < n; i++)
    {
        f2 = f0 + f1;
        f0 = f1;
        f1 = f2;
    }
    return f1;
}

Fibonacci_2�Q��用递归实现�Q?/p>

unsigned int Fibonacci_2(unsigned int n)
{
    switch (n)
    {
        case 0:
            return 1;
        case 1:
            return 1;
        default:
            return Fibonacci_2(n - 1) + Fibonacci_2(n - 2);
    }
}

��试用例�Q?/p>

TEST_T(Fibonacci_Recursive, 30)
{
    Fibonacci_2(30);
    ASSERT_TIME(0.1);
}

TEST_T(Fibonacci_Loop, 30)
{
    Fibonacci_1(30);
    ASSERT_TIME(0.1);
}

TEST_T(Fibonacci_Recursive, 40)
{
    TEST_T_SHOWTIME();
    Fibonacci_2(40);
    EXCEPT_TIME(0.1);
    ASSERT_TIME(1) << "\nUsed too long time!";
}

TEST_T(Fibonacci_Loop, 40)
{
    TEST_T_SHOWTIME();
    Fibonacci_1(40);
    EXCEPT_TIME(0.1);
    ASSERT_TIME(1) << "\nUsed too long time!";
}

��试�l�果�Q?/p>

[==========] Running 4 tests from 2 test cases.

实例中测试了四个��试用例�Q�分别测试了两个函数分别计算Fibonacci(30)和Fibonacci(40)所��p��的时间。测试用�?�?比较��单，仅有一个ASSERT_TIME断言用于��试�q�行到此该测试用例花费的旉��。测试用�?�?�Q�增加了两条语句�Q�TEST_T_SHOWTIME()�Q�测试用例结束后打印执行旉��Q�EXCEPT_TIME断言�Q�这里只是测试以下EXCEPT_TIME和ASSERT_TIME的区别，前者��l�执行后�l�语句，后者则�l�束当前的测试用例�?img src ="http://www.shnenglu.com/volant/aggbug/60203.html" width = "1" height = "1" />

看了gtest的一个simple�Q�其中有��试�q�行旉��的方法，但��用�v来稍微负责，因此做了一个简单的扩展�?/p>

扩展内容�Q?br />1. TEST_T(test_case_name, test_name)�Q�用于定义运行时间测试用例�?br />2. TEST_T_SHOWTIME()�Q�打开打印��试用例�q�行旉��打印开兟�?br />3. EXCEPT_TIME(second)和ASSERT_TIME(second)�Q�断�a��Q�second为double�c�d��Q�测试运行时间是否小于second�?/p>

使用说明�Q?br />向正�怋�用一��P��只是在需要时间测试时include “gtest_e.h”卛_��Q�当然也得把相应的库链接到执行文件中�?/p>

具体实现�Q?br />源文件gtest_e.h----

/**
* gtest_e.h
*/

#ifndef GTEST_E_H_
#define GTEST_E_H_

#include "gtest_time.h"

#define TEST_T(test_case_name, test_name)\
    GTEST_TEST(TIME_##test_case_name, test_name, ::TimeTest)

#define TEST_T_SHOWTIME() TimeTest_setShowFlag(1)

#define ASSERT_TIME(time) if(TimeTest_setTimePoint() - time > 0) \
    FAIL() << "Time: running " << TimeTest_getTime() << "(s) > " << time << "(s)"

#define EXCEPT_TIME(time) if(TimeTest_setTimePoint() - time > 0) \
    ADD_FAILURE() << "Time: running " << TimeTest_getTime() << "(s) > " << time << "(s)"

#endif /* GTEST_E_H_ */

源文件gtest_time.h----

/**
* gtest_time.h
*/

#ifndef GTEST_TIME_H_
#define GTEST_TIME_H_

#include <gtest/gtest.h>

class TimeTest: public testing::Test
{
public:
    inline void TimeTest_setShowFlag(int flag)
    {
        show_time_ = flag;
    }

    inline double TimeTest_getTime()
    {
        return end_time_ - start_time_;
    }

    double TimeTest_setTimePoint();

protected:
    double start_time_;
    double end_time_;
    int show_time_;

    virtual void SetUp();
    virtual void TearDown();
};

#endif /* GTEST_TIME_H_ */

源文件gtest_time.cpp----

/**
* gtest_time.cpp
*/

#include <iostream>
#include "gtest_time.h"

using namespace std;

#if defined(WIN32)
#include <sys/timeb.h>
double now()
{
    struct _timeb current;
    _ftime(&current);
    return (((double) current.time) + (1.0 * current.millitm) * 0.000001);
}
#else
double now()
{
    struct timeval current;
    gettimeofday(&current, NULL);
    return (((double) current.tv_sec) + 1.0e-6 * ((double) current.tv_usec));
}
#endif

void TimeTest::SetUp()
{
    start_time_ = now();
    end_time_ = 0;
    TimeTest_setShowFlag(0);
}

void TimeTest::TearDown()
{
    if (show_time_)
    {
        double used_time = TimeTest_setTimePoint();
        cout << "[   TIME   ] used time: " << used_time << "(s)"
                << endl;
    }
}

double TimeTest::TimeTest_setTimePoint()
{
    end_time_ = now();
    return TimeTest_getTime();
}

以上内容只是一个简单的实现�Q�没有过多的��试�Q�且旉��_�ֺ�不够�Q�误差较大�?img src ="http://www.shnenglu.com/volant/aggbug/60201.html" width = "1" height = "1" />
