¶C++單元測試(4) - 用VC6先試一下: 如何使用CppUnit

接續前篇，因為暫時還不想換tool寫文章！^^
就繼續VC6的使用說明。

在這裡，我們為了要先測試一下編出來的檔案對不對。
就暫時先以CppUnit CookBook中範例的最終版本當sample code吧！
為了方便之後在VS2010上做測試，就先把VC6可以跑的code貼在這。

由於UnitTest是獨立在開發專案外的另一個專案。
所以，會在下面的圖中，看見兩個專案檔，這是正常，未來上手之後也都是這樣安排的。
(不然就不叫unit test了，就用條件編譯就好啦！)

專案檔與檔案之間的設定

程式碼

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

using namespace std;

int main()
{
    Complex a(1, 3);
    Complex b(1, 3);
    Complex c = a + b;

    cout << c.real << endl;
    return 0;
}

#ifndef COMPLEX_H
#define COMPLEX_H

class Complex
{ 
    friend bool operator==(const Complex& a, const Complex& b);
    friend Complex& operator+(const Complex &a, const Complex &b);
    friend Complex& operator/(const Complex& a, const Complex& b);
public:  //just for test
    double real, imaginary;
public:
    Complex( double r, double i = 0 ): real®, imaginary(i) { }
};

bool operator==( const Complex &a, const Complex &b )
{ return (a.real == b.real)&&(a.imaginary == b.imaginary); }
Complex& operator+(const Complex &a, const Complex &b )
{ return *(new Complex(a.real + b.real, a.imaginary + b.imaginary)); }
Complex& operator/(const Complex &a, const Complex &b )
{ return *(new Complex(a.real / b.real, a.imaginary / b.imaginary)); }

    runner.addTest( registry.makeTest() );
    runner.run();

    return 0;

        m_11_2 = new Complex(11, 2);
    }

    void tearDown()
    {
        delete m_10_1;

    }

    }

    void testDivideByZeroThrows()
    {

    }
    CPPUNIT_TEST_SUITE( ComplexNumberTest );
    CPPUNIT_TEST( testEquality );
    CPPUNIT_TEST( testAddition );
    CPPUNIT_TEST_EXCEPTION( testDivideByZeroThrows, std::exception );
    CPPUNIT_TEST_SUITE_END();

設定專案檔屬性

.h檔路徑

在Additional include directiories:中填上.h檔路徑

lib檔，檔案名稱及路徑

在Object/library modules: 中填入.lib檔的檔名 在Additional library path: 中填入.lib檔放置的路徑
