Unit Testing pycaw.magic

[TurboAnonym]

@AndreMiras not yet ready 😁 just starting the discussion ...

I have thought about how to add unit testing:

• so far i tested the code visually with my GUI Magic Session Mixer that was working for me, but of course its nowhere an automatic solution. (Also it doesnt test MagicApp)
• What about uploading a free to use sound file to the test folder and use the vlc media player to play it. Then change volume and "assert" expected feedback? We could also use taskkill /F /IM vlc.exe to just kill all open vlc windows. VLC has the characteristic, that every new app window will create a new WAS (session). That way we could easily stress test pycaw (Opening a lot of windows and closing them all instantly).

Im proposing to use vlc since i cant find any other nice crossplattform solution (win 7 - 10)

• What wont work:

  Internet Explorer:

  • start iexplore music.mp3 or any other file format will download the file
  • <audio autoplay="autoplay"><source src="music.mp3" /></audio> a simple website wont work either: Problem

  Windows Media Player:

  • behaves just weird in terms of sessions - probably because its so old.

What could work:

• VLC media player (-needs to be installed)
• Powershell to play .wav link (-is ugly and I could not kill the session besides using taskkill /F /IM powershell.exe what could also interfere with the unit testing)
• Some python pip library? ...

FYI I've added a few dumb (and maybe flaky) tests in tests/test_magic.py for a start
