Introduction

For QEMU, we maintain a fork of bios bits in gitlab along with all the
dependent submodules `here <https://gitlab.com/qemu-project/biosbits-bits>`__.
This fork contains numerous fixes, a newer acpica and changes specific to
-running this avocado QEMU tests using bits. The author of this document
+running these functional QEMU tests using bits. The author of this document
is the sole maintainer of the QEMU fork of bios bits repository. For more
information, please see author's `FOSDEM talk on this bios-bits based test
framework <https://fosdem.org/2024/schedule/event/fosdem-2024-2262-exercising-qemu-generated-acpi-smbios-tables-using-biosbits-from-within-a-guest-vm-/>`__.
Description of the test framework
*********************************
-Under the directory ``tests/avocado/``, ``acpi-bits.py`` is a QEMU avocado
-test that drives all this.
+Under the directory ``tests/functional/``, ``test_acpi_bits.py`` is a QEMU
+functional test that drives all this.
A brief description of the various test files follows.
-Under ``tests/avocado/`` as the root we have:

- This is the main python avocado test script that generates a
+ ``test_acpi_bits.py``:
+ This is the main python functional test script that generates a
biosbits iso. It then spawns a QEMU VM with it, collects the log and reports
test failures. This is the script one would be interested in if they wanted
to add or change some component of the log parsing, add a new command line
you to inspect and run the specific commands manually.
In order to run this test, please perform the following steps from the QEMU
- build directory:
+ build directory (assuming that the sources are in ".."):
::
- $ make check-venv (needed only the first time to create the venv)
- $ ./pyvenv/bin/avocado run -t acpi tests/avocado
+ $ export PYTHONPATH=../python:../tests/functional
+ $ export QEMU_TEST_QEMU_BINARY=$PWD/qemu-system-x86_64
+ $ python3 ../tests/functional/test_acpi_bits.py
- The above will run all acpi avocado tests including this one.
- In order to run the individual tests, perform the following:
- ::
-
- $ ./pyvenv/bin/avocado run tests/avocado/acpi-bits.py --tap -
-
- The above will produce output in tap format. You can omit "--tap -" in the
- end and it will produce output like the following:
- ::
-
- $ ./pyvenv/bin/avocado run tests/avocado/acpi-bits.py
- Fetching asset from tests/avocado/acpi-bits.py:AcpiBitsTest.test_acpi_smbios_bits

- RESULTS : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
- JOB TIME : 39.22 s
+ The above will run all acpi-bits functional tests (producing output in
