Setting $SYSFS_PATH does not work any more with recent libudev versions, our
homwbrew sysfs sandbox building limits us to coldplug tests only. umockdev
works with both old and new libudevs and can also emulate uevents for future
hotplugging tests.
Skip the test if umockdev is not available, so that check and distcheck don't
bail out.
Crash the daemon on any CRITICAL message, and also set WARNING and CRITICAL
messages to be fatal on the client side. On the server side we might have some
legitimate warnings, such as failing to load the config file from
/usr/local/etc (if you build a tree without passing correct --sysconfdir
options, etc.).
This exposes the current CRITICAL the daemon raises at startup. As with that
the daemon never starts up, fix the "wait for the daemon" loop to time out
after 10 seconds.
This reverts commit 14761c09d2.
The real reason for the failure is that Makefile.am calls the script with
"python" which is Python 2, but we need Python 3.
unittest.TestCase unfortunately does not have any public API to check whether
a test case succeeded, so we use the private self._outcomeForDoCleanups. This
does not seem to exist every time, so avoid a crash if it doesn't.
So far the test cases only covered drivers which reported energy (µWh). Add
checks that the Energy* properties are correct, and add a test case for drivers
which report charge (µAh).
If possible, run the tests under dbus-launch to ensure that there is a private
D-BUS session bus. This allows the tests to work in e. g. a clean package build
environment, and also avoids messing with the real user session bus.
Add src/linux/integration-test: This is a Python unittest based test suite
which provides methods for building a sandbox sysfs tree, runs upowerd
in it, and checks for correct properties.
As it is really hard to provide fake uevents, this currently only works for
properties which do not depend on dynamic system changes, i. e. you can
currently only check the status after coldplugging.
However, this already provides enough possibilities for functionality and
regression testing, and exposes some bugs with determining the "OnBattery"
property under certain conditions like the ones described in
<https://bugs.freedesktop.org/show_bug.cgi?id=24371>.
If any of the tests fails, the daemon log will be printed to stderr for easier
debugging.
With the previous commit that adds "upowerd --test", we can also run
the integration tests as non-root. If they are called as root, start upowerd
normally on the system bus, otherwise on the session bus with --test.
