    void testCtorAndGetName()

int main()
{
    CPPUNIT_NS::TestResult r;
    CPPUNIT_NS::TestResultCollector result;
    r.addListener( &result );
    CPPUNIT_NS::TestCallertestCase1( "testCtorAndGetName", MyTestCase::testCtorAndGetName );
    CPPUNIT_NS::TestCallertestCase2( "testGetFileSize", MyTestCase::testGetFileSize );
    CPPUNIT_NS::TestCallertestCase3( "testFileExist", MyTestCase::testFileExist );
    CPPUNIT_NS::TestCallertestCase4( "testFileModifyDateBasic", MyTestCase::testFileModifyDateBasic );
    CPPUNIT_NS::TestCallertestCase5( "testFileModifyDateEqual", MyTestCase::testFileModifyDateEqual );
    testCase1.run( &r );
    testCase2.run( &r );
    testCase3.run( &r );
    testCase4.run( &r );
    testCase5.run( &r );
    CPPUNIT_NS::TextOutputter out( &result, std::cout );
    out.write();
    return 0;
}

这里的TestCaller可以把从TestFixture派生而来的类的成员函数转化为一个TestCase。这段代码可以编译通过，运行后一共进行了5个测试，完全失败。这是我们意料之中的结果，因此我们进一步实现我们的功能，完成后的代码为：
