TL;DR
=====
Another version, with a minimalist approach, of the acceptance tests
infrastructure for QEMU, based on the Avocado Testing Framework.
Background
==========
The previous version, still considered an RFC, sent to the list by
Eduardo[1] was based on the work held in Amador's branch[2]. After
reviewing it under a different light, including the experiences
done and reported by Philippe[3], it was clear to me that a different
approach would be better.
Differences from previous versions
==================================
The main difference is that this series include only the minimal
changes deemed necessary to have a starting point. I like to think
that it's better connected to the QEMU community and project needs,
and will hopefully allow for a more organic growth.
Since this version has less features than the previous versions,
provided it's accepted, these are the next probable development tasks:
* Provide a simple variants mechanism to allow the same tests to be
run under different targets, machine models and devices (present on
the previous versions as a "YAML to Mux" file with architecture
definitions)
* Implement QEMUMachine migration support (present on the previous
version in the "avocado_qemu.test._VM" class)
* Implement Guest OS image selection and download (mostly an Avocado
feature, paired with a parameter convention and cloud-init support
code)
* Implement interactive support for Guest OS sessions (present on
the previous versions, supported by the aexpect Python module)
* Move the Python modules that are used on tests to a more proper
"module" organization. This should allow for a proper place
to hold tests for the Python modules themselves.
Even though this version shares very little (if any) code with the
previous versions, the following is a list of noteworthy changes:
* Tests directory is now "tests/acceptance" (was "tests/avocado")
* Base test class is now "avocado_qemu.Test" (was
"avocado_qemu.test.QemuTest")
* Base test class is now hosted in "avocado_qemu/__init__.py" (was
"avocado_qemu/test.py")
* Direct use of "qemu.QEMUMachine", that is, the
avocado_qemu.test._VM class is gone
* avocado_qemu.Test won't search for QEMU binaries on $PATH. To use
QEMU binary on a custom system location it's necessary to use the
"qemu_bin" parameter
* Example test in README.rst is distributed as a real test
("test_version.py")
* A new "Linux boot console" test, loosely modeled after Phillipe's
use case
Changes
=======
>From v3:
--------
* Gave more information on the meaning/intended use of acceptance
tests
* Added a clearer example on running tests with tags
* Added more information on what a QEMUMachine is
>From v2
-------
* Renamed acceptance test files, dropping "test_" prefix.
* Dropped "scripts/test_qemu.py" until we have a proper Python module
location on which to put their own tests.
>From v1
-------
* Moved documentation to docs/devel/testing.rst
* Changed code markers from "::" to ".. code::" in the documentation
for consistency
* Added copyright notices
* Removed useless "qemu_bin=None" attribution on avocado_qemu.Test.setUp()
* Removed reference about setting arguments, instead of appending them,
on "Acceptance tests: add quick VNC tests" commit message
* Fixed typo (s/inteligence/intelligence/) on "scripts/qemu.py:
introduce set_console() method" commit message
* Removed useless "return" in add_args()
Commit summary
==============
Cleber Rosa (5):
Add functional/acceptance tests infrastructure
scripts/qemu.py: allow adding to the list of extra arguments
Acceptance tests: add quick VNC tests
scripts/qemu.py: introduce set_console() method
Acceptance tests: add Linux kernel boot and console checking test
