commit 9fc661d8635de915a2d1f532ad2477ae1ff9bf39
Author: Sam Thursfield <sam afuera me uk>

functional-tests: Add mock-volume-monitor GIO module
This is our best option for testing Tracker's removable device handling
code, see: https://discourse.gnome.org/t/testing-removable-usb-devices/7297
You can test-drive the module by running this command in the build tree:
env GIO_USE_VOLUME_MONITOR=mockvolumemonitor
GIO_MODULE_DIR=$(pwd)/tests/functional-tests/mockvolumemonitor gio mount --monitor
The module is operated over D-Bus, to create a fake mount you can do
this:
gdbus call --session --dest org.freedesktop.Tracker3.MockVolumeMonitor \
--object-path /org/freedesktop/Tracker3/MockVolumeMonitor \
--method org.freedesktop.Tracker3.MockVolumeMonitor.AddMount file:///tmp/mymount
