[TIP] problems w/ coverage and threads?

[Dirk Pranke]

Hi all,

I'm running the following program under coverage on a Mac Pro running
Snow Loepard (using "coverage run threads_unittest.py", python 2.5,
coverage 3.3.1) and getting no coverage numbers from the
TestThread.run()
method. Also, if I try to mark it ignored with "# pragma: no cover",
that seems to have no effect.

I would have thought that both of these things would work. Any ideas?

        threading.Thread.__init__(self)

        self._stopping_queue = stopping_queue

    def run(self):
        print "starting thread"

        thd.join()
        self.assertTrue(True)
