This looks like a unit test, not Nevow code?

Return your ultimate result here; note that if you're not actually
going to do anything to result in cb_result, you could just have:

def cb_execute(result):
    return result.get_one()

return self.store.execute("SELECT title FROM foo WHERE
id=10").addCallback(cb_execute)

The result returned from cb_result is what will ultimately used by
whatever invoked test_execute, assuming that it pays attention to the
return value; I'm not clear how test_execute is being used, so I can't
say this will work for sure. If test_execute is, for example, a render
method, then it should work just fine.
