Yes, I did read QThread::wait() before I posted the question. The quit()
slot is QThread::quit(), not the application's quit().

That's what I want to do in the test is to terminate the thread with a 1
second delay. The destructor will be called by the main() function when
the thread object is about to go out of scope. At this moment, I want to
wait for the thread termination (ideally, in about 1 second) before I
finally destruct the thread.

In fact, my initial test was to connect timeout() signal to my own slot
that does qDebug(). But nothing turned out on the console, which was why
I decided to use QThread's own slots for verification.

So, still, I cannot get the timer's timeout() signal to fire in all my
current tests...

Sorry if I didn't make the case clear enough earlier.
