[Qemu-devel] [PATCH v3 2/3] Acceptance tests: add make rule for running


From: Cleber Rosa
Subject: [Qemu-devel] [PATCH v3 2/3] Acceptance tests: add make rule for running them
Date: Tue, 9 Oct 2018 13:57:39 -0400

The acceptance (aka functional, aka Avocado-based) tests are
Python files located in "tests/acceptance" that need to be run
with the Avocado libs and test runner.

Let's provide a convenient way for QEMU developers to run them,
by making use of the tests-venv with the required setup.

Also, while the Avocado test runner will take care of creating a
location to save test results to, it was understood that it's better
if the results are kept within the build tree.

+You can run the acceptance tests simply by executing:

+
+This involves the automatic creation of Python virtual environment
+within the build tree (at ``tests/venv``) which will have all the
+right dependencies, and will save tests results also within the
+build tree (at ``tests/results``).
+
+Note: the build environment must be using a Python 3 stack, and have
+the ``venv`` and ``pip`` packages installed.  If necessary, make sure
+``configure`` is called with ``--python=`` and that those modules are
+available.  On Debian and Ubuntu based systems, depending on the
+specific version, they may be on packages named ``python3-venv`` and
+``python3-pip``.
