在VC下使用CppUnit做单元测试的简单步骤

    1.取得Cppunit发行版本,下载的是cppunit-1.10.2
    2.使用INSTALL-WIN32.txt，
    3.查看examples中的例子，观看其配置。

Libraries:
----------

All the compiled libraries and DLL can be found in the 'lib' directory.
Most libraries can be build from src/CppUnitLibraries.dsw workspace.

    lib\:
    cppunit.lib    : CppUnit static library "Multithreaded DLL"
    cppunitd.lib   : CppUnit static library "Debug Multithreaded DLL"
    cppunit_dll.dll   : CppUnit dynamic library (DLL) "Multithreaded DLL"
    cppunit_dll.lib   : CppUnit dynamic import library "Multithreaded DLL"
    cppunitd_dll.dll : CppUnit dynamic library (DLL) "Debug Multithreaded DLL"
    cppunitd_dll.lib : CppUnit dynamic import library "Debug Multithreaded DLL"
    qttestrunner.dll : QT TestRunner dynamic library (DLL) "Multithreaded DLL"
    qttestrunner.lib : QT TestRunner import library "Multithreaded DLL"
    testrunner.dll   : MFC TestRunner dynamic library (DLL) "Multithreaded DLL"
    testrunner.lib   : MFC TestRunner import library "Multithreaded DLL"
    testrunnerd.dll   : MFC TestRunner dynamic library (DLL) "Debug Multithreaded DLL"
    testrunnerd.lib   : MFC TestRunner import library "Debug Multithreaded DLL"
    testrunneru.dll   : MFC Unicode TestRunner dynamic library (DLL) "Multithreaded DLL"
    testrunneru.lib   : MFC Unicode TestRunner import library "Multithreaded DLL"
    testrunnerud.dll : MFC Unicode TestRunner dynamic library (DLL) "Debug Multithreaded DLL"
    testrunnerud.lib : MFC Unicode TestRunner import library "Debug Multithreaded DLL"
    TestRunnerDSPlugIn.dll : The add-in you register in VC++.

A. 新建一个MFC应用程序

B. 在“工具”－选项－目录

C. 在工程配置里面选择RTTI

Link下加入 Debug\cppunitd.lib Debug\testrunnerd.lib ，记得把这辆个文件从cppunit-1.10.2\lib拷出来，把相应的dll文件也拷到 debug目录下

     D. 在App初始化函数中App::InitInstance()的开头加入
#include <cppunit/ui/mfc/TestRunner.h>
#include <cppunit/extensions/TestFactoryRegistry.h>
在其中加入
CppUnit::MfcUi::TestRunner runner;
runner.addTest( CppUnit::TestFactoryRegistry::getRegistry().makeTest() );
runner.run();
记得把原来的窗口注掉，不然调用的还是原来的窗口。

E. 加入要测的类叫XXX
我们起这个类的测试叫testXXX 类

#include <cppunit/TestCase.h>
#include <cppunit/extensions/HelperMacros.h>

#include "testXXX .h"

class testXXX : public CppUnit::TestCase
{
CPPUNIT_TEST_SUITE(testXXX );
CPPUNIT_TEST(testcase1); //这里就是我们的testcase的函数原型名字
CPPUNIT_TEST(testcase2);
CPPUNIT_TEST_SUITE_END();

public:
void setUp();
void tearDown();

protected:
void testcase1();//声明我们的测试函数
void testcase2();

private:
testXXX *fixture;

};

其cpp文件必须要有

CPPUNIT_TEST_SUITE_REGISTRATION(testXXX);
然后
void testXXX::setUp()
{
fixture = new testXXX();//当然要按照实际的类构造你的测试对象了
}

void testXXX::tearDown()
{
delete fixture;
fixture = NULL;//析构你的测试对象
}

下面就是你的测试函数

void testXXX::testcase1()
{
     CPPUNIT_ASSERT(condition1);//如果condition1为false激发这个assert
     CPPUNIT_ASSERT_MESSAGE(”msg“ , condition2);
    ……
}

第二个类似这样就可以
运行结果类似于下面的窗口

ok，好多东西我还没有使用，今天就到这里，不过感觉挺好设置的，还是觉得比较麻烦了些，在MinGW Developer Studio不知道能否使用，我还没有使用过，赶明儿试试。
