# Copyright (C) 2013 Intel Corporation
#
# Released under the MIT license (see COPYING.MIT)
# testimage.bbclass enables testing of qemu images using python unittests.
# Most of the tests are commands run on target image over ssh.
# To use it add testimage to global inherit and call your target image with -c testimage
# You can try it out like this:
# - first build a qemu core-image-sato
# - add INHERIT += "testimage" in local.conf
# - then bitbake core-image-sato -c testimage. That will run a standard suite of tests.
# You can set (or append to) TEST_SUITES in local.conf to select the tests
# which you want to run for your target.
# The test names are the module names in meta/lib/oeqa/runtime.
# Each name in TEST_SUITES represents a required test for the image. (no skipping allowed)
# Appending "auto" means that it will try to run all tests that are suitable for the image (each test decides that on it's own).
# Note that order in TEST_SUITES is important (it's the order tests run) and it influences tests dependencies.
# A layer can add its own tests in lib/oeqa/runtime, provided it extends BBPATH as normal in its layer.conf.
# TEST_LOG_DIR contains a ssh log (what command is running, output and return codes) and a qemu boot log till login
# Booting is handled by this class, and it's not a test in itself.
# TEST_QEMUBOOT_TIMEOUT can be used to set the maximum time in seconds the launch code will wait for the login prompt.
