class FakeBackend

Defined at line 24 of file ../../src/devices/bus/lib/virtio/include/lib/virtio/backends/fake.h

FakeBackend allows writing tests of virtio device drivers.

Tests may subclass FakeBackend and override certain functions to check device/driver

interactions. FakeBackend also provides a small amount of helper functionality itself - it

checks the device initialization state machine, tracks valid queues/sizes, and valid config

registers.
