#9 Providing a global setup decorator for running test cases

[Jason Diamond]

Since the MFC TestRunner runs each test on a separate
thread, the COM components that I was trying to test
were failing because CoInitialize was not called for
the thread that separate thread.

My fix was simple. Just call CoInitialize and
CoUninitialize in ActiveTest::threadFunction:

// Simple execution thread. Assuming that an
ActiveTest instance
// only creates one of these at a time.
UINT ActiveTest::threadFunction (LPVOID thisInstance)
{
ActiveTest *test = (ActiveTest *)thisInstance;

bool comInit = SUCCEEDED( CoInitialize( NULL ) );

test->run ();
test->m_runCompleted.SetEvent ();

if ( comInit )
CoUninitialize();

return 0;
}

This works for me because my components are STA but a
more general solution is needed to handle testing in
other threading models. Perhaps by passing in some
parameters to the TestRunner constructor.

I aware of that problem. This will be adressed in a future
release by providing a global 'setup decorator' when
running test.

In the meantime, you can either use a common base class for
all your test that require CoInitialize, or use the text
mode test runner.

It is now possible to provide TestListener to do some global
set up, but the MFC TestRunner still need to be reworked to
support this feature.
