This set of patches adds an automatic test of the vmstate via the
scripts/vmstate-static-checker.py script. For this we need some
reference files from an older version of QEMU. I chose to use QEMU 7.2
for the reference files since this is a long term support release that
is still actively being maintained, so we certainly want to make sure
that we don't break migration from that version to the latest one.
There are also some files available in tests/vmstate-static-checker-data/
which were used in the past to verify the functionality of the checker
script. Move them to tests/data/vmstate-static-checker now and add an
automated test for this task, too.
Since the checker script can report false positives in certain cases,
the tests are marked with the "skipFlakyTests" decorator, i.e. they
are only run if the user set the QEMU_TEST_FLAKY_TESTS environment
variable before starting the tests.
v3:
- Do not run the tests by default, only if QEMU_TEST_FLAKY_TESTS has
been set
- Add some hints what to do in case the test detects an error
v2:
- Dropped the patch that is already upstream
- Don't remove the old dump files, rather test for the expected
output of the checker script with them
Thomas Huth (4):
tests: Move the old vmstate-static-checker files to tests/data/
tests/data/vmstate-static-checker: Add dump files from QEMU 7.2.17
tests/functional: Test with scripts/vmstate-static-checker.py
tests/functional/test_vmstate: Test whether the checker script works
as expected
