Question

您好我有一个名为Date的c ++类。代码如下。如何为班级创建测试运行？对C ++来说非常新。我搜索了很多，但无法找到任何富有成效/有用的网站。请有人可以帮忙吗？提前谢谢。

date.h

#ifndef H_date
#define H_date 
#include <iostream> 
using namespace std; 
class Date{
    friend ostream &operator << (ostream & os, const Date &);
    friend istream &operator >> (istream & is, Date &);

public:
    Date();
    Date(int day, int month, int year);
    void setday(int day);
    void setmonth(int month);
    void setyear(int year);
    void setDate(int day, int month, int year);
    int getday() const;
    int getmonth() const;
    int getyear() const;
    void print() const;
protected:
    int day;
    int month;
    int year; 
};
#endif

date.cpp

#include <iostream>
#include "date.h"
using namespace std;
Date::Date()
{
    day = 0;
    month = 0;
    year = 0;
}
Date::Date(int newDay, int newMonth, int newYear)
{
    day = newDay;
    month = newMonth;
    year = newYear;
}
void Date::setday(int newDay)
{
    day =newDay;
}
void Date::setmonth(int newMonth)
{
    month = newMonth;
}
void Date::setyear(int newYear)
{
    year = newYear;
}

void Date::setDate(int newDay, int newMonth, int newYear)
{
    day =newDay;
    month = newMonth;
    year = newYear;
}
int Date::getday()const
{
    return day;

}
int Date::getmonth()const
{
    return month;

}
int Date::getyear()const
{
    return year;

}

void Date::print()const
{
    cout << day << ":" << month<< ":" << year <<endl;
}
ostream& operator<< (ostream& osObject, const Date& date1)
{
    osObject << date1.day
        << ":" <<date1.month
        << ":" << date1.year;
    return osObject;

}
istream& operator>> (istream& isObject, Date& date1)
{
    isObject>>date1.day>>date1.month>>date1.year;
    return isObject;

}

对于单元测试，您通常会使用单位测试框架，例如CppUnit：

对于每个班级，您都要创建一系列测试;
对于每个要测试的方法，您都要开发专用测试;
每个测试使用CPPUNIT_ASSERT，CPPUNIT_FAIL，CPPUNIT_ASSERT_THROW等函数或宏验证某些断言;
将测试人员friend分类到测试类通常很有用。

以下是测试构造函数的示例：

void DateUnitTest::ConstructorTests
{
    // Test default-ctor
    { 
        Date date;
        CPPUNIT_ASSERT ( date.day   == 0 );
        CPPUNIT_ASSERT ( date.month == 0 );
        CPPUNIT_ASSERT ( date.year  == 0 );
    }

    // Test ctor with args
    { 
        Date date(31,12,2015);
        CPPUNIT_ASSERT ( date.day   == 31 );
        CPPUNIT_ASSERT ( date.month == 12 );
        CPPUNIT_ASSERT ( date.year  == 2015 );
    }
}

如何为C ++程序创建测试运行/计划？
