[v1] tests: Fix qemuxml2xmltest with audio driver defined in env

[PATCH] tests: Fix qemuxml2xmltest with audio driver defined in env

Posted by Jim Fehlig 3 years, 1 month ago

If QEMU_AUDIO_DRV is defined in the build host environment, several tests
in qemuxml2xmltest fail.

$ env | grep -i audio
AUDIODRIVER=pulseaudio
QEMU_AUDIO_DRV=pa
SDL_AUDIODRIVER=pulse

An example test failure with the above environment

907) QEMU XML-2-XML-active video-virtio-gpu-sdl-gl
In 'libvirt/tests/qemuxml2xmloutdata/video-virtio-gpu-sdl-gl.xml':
Offset 1244
Expect [v]
Actual [audio id='1' type='pulseaudio'/>
    <v]

Scrub QEMU_AUDIO_DRV from the environment before executing the tests in
qemuxml2xmltest.

On IRC Daniel suggested scrubbing QEM_AUDIO_DRV and SDL_AUDIODRIVER.
Only QEM_AUDIO_DRV was needed to fix the test failure, but I can scrub
the other one too if that's preferred.

I think we should do both as qemu_domain.c will look at SDL_AUDIODRIVER
if $QEMU_AUDIO_DRV == sdl
