Test case groups
----------------
"Tests may belong to one or more test groups, which are defined in the form
of a comment in the test source file. By convention, test groups are listed
in the second line of the test file, after the "#!/..." line, like this:
.. code::
#!/usr/bin/env python3
# group: auto quick
#
...
Another way of defining groups is creating the tests/qemu-iotests/group.local
file. This should be used only for downstream (this file should never appear
in upstream). This file may be used for defining some downstream test groups
or for temporarily disabling tests, like this:
.. code::
# groups for some company downstream process
#
# ci - tests to run on build
# down - our downstream tests, not for upstream
#
# Format of each line is:
# TEST_NAME TEST_GROUP [TEST_GROUP ]...
013 ci
210 disabled
215 disabled
our-ugly-workaround-test down ci
Note that the following group names have a special meaning:
- quick: Tests in this group should finish within a few seconds.
- auto: Tests in this group are used during "make check" and should be
runnable in any case. That means they should run with every QEMU binary
(also non-x86), with every QEMU configuration (i.e. must not fail if
an optional feature is not compiled in - but reporting a "skip" is ok),
work at least with the qcow2 file format, work with all kind of host
filesystems and users (e.g. "nobody" or "root") and must not take too
much memory and disk space (since CI pipelines tend to fail otherwise).
- disabled: Tests in this group are disabled and ignored by check.

# QA groups control file
# Defines test groups
#
# Some notes about the groups:
#
# - do not start group names with a digit
#
# - quick : Tests in this group should finish within some few seconds.
#
# - img : Tests in this group can be used to excercise the qemu-img tool.
#
# - auto : Tests in this group are used during "make check" and should be
# runnable in any case. That means they should run with every QEMU binary
# (also non-x86), with every QEMU configuration (i.e. must not fail if
# an optional feature is not compiled in - but reporting a "skip" is ok),
# work at least with the qcow2 file format, work with all kind of host
# filesystems and users (e.g. "nobody" or "root") and must not take too
# much memory and disk space (since CI pipelines tend to fail otherwise).
