这个CppUnit包是POCO中的CppUnit的简化版本，但是开展测试C++的测试用例来说已经足够了。

2、代码示例

类foo，完成加法，等功能

class CFoo{public:    int a(int a, int b)    {        return a + b;    }    char c()    {        return 'c';    }    void t()    {        throw std::exception("foo exception.");    }};

继承自TestCase的单元测试类

#include "CppUnit/TestCaller.h"#include "CppUnit/TestSuite.h"class CFooTest: public CppUnit::TestCase{public:    CFooTest(const std::string& name):CppUnit::TestCase(name)    { }    ~CFooTest()    { }    void testa()    {        CFoo foo;        int a = foo.a(1,2);        assert(3 == a);        char *p = NULL;        assertEqual(1.3,1.3);    }    void testc()    {        CFoo foo;        assert(foo.c() == 'c');    }    void testt()    {        CFoo foo;        try        {            foo.t();            fail("will not run.");        }        catch (std::exception& )        {        }    }    void testThrow()    {        CFoo foo;        foo.t();    }    void setUp()    { }    void tearDown()    { }    static CppUnit::Test* suite()    {        CppUnit::TestSuite* pSuite = new CppUnit::TestSuite("CFooTestSuite");        CppUnit_addTest(pSuite,CFooTest,testa);        CppUnit_addTest(pSuite,CFooTest,testc);        CppUnit_addTest(pSuite,CFooTest,testt);        CppUnit_addTest(pSuite,CFooTest,testThrow);        return pSuite;    }};

main函数

#include "CppUnit/TestRunner.h"#include "CppUnit/TextTestResult.h"#include "CppUnit/TestSuite.h"int main(){    /* 终极suite，将其他suite都包到里面来 */    CppUnit::TestSuite* pSuite = new CppUnit::TestSuite("main");    pSuite->addTest(CFooTest::suite());    // pSuite->addTest Other suites.    // TestRunner用于运行测试用例    CppUnit::TestRunner runnre;    runnre.addTest("main",pSuite);    std::vector<std::string> args;    args.push_back("drive");    args.push_back("-all");    args.push_back("-print");    runnre.run(args);    return 0;}
