Interesting why set_option test fails with Exception: SegFault, even though it clearly looks like the failure reason is "no USB devices found".
Probably need to investigate/think how to workaround it.

@mcuee any ideas? Do we have somthing like "virtual USB device" on Linux for tests?
Or should I disable the test on CI?

In order to run umockdev test, you need to intall two packages first: umockdev libumockdev-dev. It is a Linux specific test.

For set_option, you may have to disable the test for CI.
