As the xvfb-run manpage says, it uses a default server number of 99:
> -n servernumber, --server-num=servernumber
> Use servernumber as the server number (but see the -a, --auto-servernum option above). The default is 99.
The gtk3 a11y tests use xvfb-run. Running the test multiple
times in parallel (e.g. when doing two separate builds with
tests, as happens on CI) would fall like this on Debian testing:
$ make CppunitTest_vcl_gtk3_a11y
make -j 12 -rs -f /home/michi/development/git/libreoffice/Makefile.gbuild CppunitTest_vcl_gtk3_a11y
[CUT] vcl_gtk3_a11y
xvfb-run: error: Xvfb failed to start

Error: a unit test failed, please do one of:
make CppunitTest_vcl_gtk3_a11y CPPUNITTRACE="gdb --args"
# for interactive debugging on Linux
make CppunitTest_vcl_gtk3_a11y VALGRIND=memcheck
# for memory checking
make CppunitTest_vcl_gtk3_a11y DEBUGCPPUNIT=TRUE
# for exception catching
You can limit the execution to just one particular test by:
make CPPUNIT_TEST_NAME="testXYZ" ...above mentioned params...
However, it behaves differently on Alma Linux 8, where it
looks like xvfb-run seems then to reuse the existing
Xfvb session, causing the tests to potentially find
the LibreOffice instance from another test run, and
then inspecting the wrong one, leading to failures
like the one in [1]:
equality assertion failed
- Expected: ecclectic.fodt — LibreOfficeDev Writer
- Actual : ecclectic.fodt — LibreOfficeDev Writer 24.2 [9bc2aede99]
The fact that the second instance of xvfb-run
reuses the session of the firs one and finds the
LibreOffice there can also be reproduced on Alma Linux 8
by just running these 2 commands in parallel:
1) start LO in xfvb-run session:
$ xvfb-run dbus-launch libreoffice
2) run below Python script that lists the
running applications:
$ xvfb-run dbus-launch python3 /home/vagrant/atspi-list-apps.py
--------start--------
[application | soffice]
--------end--------
/usr/bin/xvfb-run: line 186: kill: (27078) - No such process
This *should not* list the applications from
the other xfvb-run.
It works as expected when passing `--auto-servernum`:
$ xvfb-run --auto-servernum dbus-launch python3 /home/vagrant/atspi-list-apps.py
--------start--------
--------end--------
Therefore, pass the `--auto-servernum` arg to xvfb-run, so that it
automatically determines a free server number instead.
> -a, --auto-servernum
> Try to get a free server number, starting at 99, or the argument to --server-num.
Python script mentioned above used for testing:
$ cat atspi-list-apps.py
#!/usr/bin/python3
import pyatspi
registry = pyatspi.registry.Registry()
apps = list(registry.getDesktop(0))
print('--------start--------')
for app in apps:
print(f'{app}')
print('--------end--------')
