Re: [Discuss-gnuradio] Python Unit Tests Running Twice

[Dave NotTelling]

Kevin,

     The radio is released properly when the destructor is called, but it's not getting called for some reason.  I have several C++ tests that work like a champ, but the Python test doesn't actually release the resources that were allocated.  I even tried assigning my block that talks to the radio to a variable in self (self.radio) and then setting it to None in the tearDown method.  The resources still are not released.  If I stop a GNU Radio flow graph that uses my block then everything is released just fine.  Even when the Python test finishes (after the second run) the resources are released.  It's just that the resources are not released between the back to back runs of the same test.

     I completely agree that releasing the resources should be tested as well.  This just seems like an odd bug to me.  My Python isn't all that great so it's completely possible that I'm not doing something right =\

You wrote originally that the reason the tests can't be run twice is “the radio hardware is never released.” This sounds like a problem that can be solved by making sure your test (by way of the code it tests, presumably) releases the hardware properly. Then your tests are also testing "releasing"!

I recommend this course of action because I have had trouble resulting from other people's drivers failing to close/release/reset the hardware properly, or to be unable to be opened twice.
