Sounds good, as I read this you only add new functionality so nothing
existing ought to be affected.
Not sure how much of our CI uses umockdev, but please do keep an eye on
it (I'm sure you will anyway).
Go ahead.

Title:
FFE: record/replay of input devices using the evemu format
Status in “umockdev” package in Ubuntu:
Confirmed
Bug description:
So far umockdev uses a "verbatim binary data" format for recording and
replaying device behaviour. The Mir team (in particular, Chris Halse
Rogers) has worked on creating automatic tests that simulate touchpad
events. Unfortunately the "struct input_event" is platform dependent
as it has time_t members, which is a "long" (i. e. 32 bit on i386/arm,
and 64 bit o amd64 and others). Thus recorded scripts don't run on
other platforms.
So I got asked to implement recording and replaying of input devices
using the "evemu event" format, which is textual and platform
independent. (https://github.com/martinpitt/umockdev/issues/5). I did
that now, and released it in umockdev 0.8:
-------------------------------------------
New features:
- Add new method umockdev_testbed_load_evemu_events() to replay an evemu
events
file into an emulated evdev device. These are platform independent and thus
more portable than a script record.
- Add -e/--evemu-events=devname=eventsfilename option to umockdev-run, to load
an evemu .events file. (Issue #5)
- Add -e/--evemu-events=devname=eventsfilename option to umockdev-record, to
record reads from an evdev device into an evemu .events file. (Issue #5)
- Add umockdev_in_mock_environment(). This function returns whether
or not the current process is running in a umockdev testbed
environment. Thanks Chris Halse Rogers!
Bug fixes:
- Only send a "add" uevent from add_device if running in a umockdev
testbed environment. Fixes error messages when loading devices from
the umockdev-run commandline. Thanks Chris Halse Rogers!
- Fix detection of mismatching devices when recording into an already existing
ioctl or script record file.
-------------------------------------------
The new evemu feature is covered by new test cases and don't change
behaviour of existing functionality (ioctls, scripts, etc.). Also,
umockdev is a pure testing tool, not an user application, so it does
not impact released images. There is a potential risk to break tests
which are currently succeeding, but I will take responsibility of
fixing any regression which comes due to that.
