MfcTestRunner assertion

[berc]

Hello,

I am attempting insert CppUnit test suite directly to my MFC windows application.
With TextTestRunner is not any problem.
But when I try use MfcTestRunner it assert in run() function:

bool cdxCDynamicWndEx::RestoreWindowPosition(LPCTSTR lpszProfile,
                                             const CString &entryPrefix,
                                             UINT restoreFlags)
{
    if(!IsWindow() || !lpszProfile || !*lpszProfile)
    {
        ASSERT(false);
        return false;
    }

    CWnd        *pWnd    =    Window();
    CWinApp    *app    =    AfxGetApp();

    if(!app->m_pszRegistryKey || !*app->m_pszRegistryKey)

part of source code is:
    void CMyWinApp::OnUnitTest()
    {
        CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
pFrame->m_pMsgWait->ShowInfo(MAKESTRING(IDS_INFO3009));

        // declare a test runner, fill it with our registered tests and run them
        CppUnit::MfcTestRunner runner;
        runner.addTest( CppUnit::TestFactoryRegistry::getRegistry().makeTest() );
        runner.run();
...

Please, can anybody tell me, where can be problem and if using of MfcTestRunner is possible directly in tested CWinApp?

Thanks for ansfer.

(assertion:
CWinApp *app =AfxGetApp(); returns 0x00000000 value)
