# 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 add IMAGE_CLASSES += "testimage" in local.conf
# - build a qemu core-image-sato
# - then bitbake core-image-sato -c testimage. That will run a standard suite of tests.
#
# The tests can be run automatically each time an image is built if you set
# TESTIMAGE_AUTO = "1"

TESTIMAGE_AUTO ??= "0"

# When any test fails, TESTIMAGE_FAILED_QA ARTIFACTS will be parsed and for
# each entry in it, if artifact pointed by path description exists on target,
# it will be retrieved onto host

TESTIMAGE_FAILED_QA_ARTIFACTS ??= "\
    ${localstatedir}/log \
    ${sysconfdir}/version \
    ${sysconfdir}/os-release"

# 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/cases.
# 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 relevant: tests are run in an order such that
# tests mentioned in @skipUnlessPassed run before the tests that depend on them,
# but without such dependencies, tests run in the order in which they are listed
# in TEST_SUITES.
#
# 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 command ssh log and may contain infromation about what command is running, output and return codes and for qemu a 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.
# TEST_OVERALL_TIMEOUT can be used to set the maximum time in seconds the tests will be allowed to run (defaults to no limit).
# TEST_QEMUPARAMS can be used to pass extra parameters to qemu, e.g. "-m 1024" for setting the amount of ram to 1 GB.
# TEST_RUNQEMUPARAMS can be used to pass extra parameters to runqemu, e.g. "gl" to enable OpenGL acceleration.
# QEMU_USE_KVM can be set to "" to disable the use of kvm (by default it is enabled if target_arch == build_arch or both of them are x86 archs)

# TESTIMAGE_BOOT_PATTERNS can be used to override certain patterns used to communicate with the target when booting,
# if a pattern is not specifically present on this variable a default will be used when booting the target.
# TESTIMAGE_BOOT_PATTERNS[<flag>] overrides the pattern used for that specific flag, where flag comes from a list of accepted flags
# e.g. normally the system boots and waits for a login prompt (login:), after that it sends the command: "root\n" to log as the root user
# if we wanted to log in as the hypothetical "webserver" user for example we could set the following:
# TESTIMAGE_BOOT_PATTERNS = "send_login_user search_login_succeeded"
# TESTIMAGE_BOOT_PATTERNS[send_login_user] = "webserver\n"
# TESTIMAGE_BOOT_PATTERNS[search_login_succeeded] = "webserver@[a-zA-Z0-9\-]+:~#"
# The accepted flags are the following: search_reached_prompt, send_login_user, search_login_succeeded, search_cmd_finished.
# They are prefixed with either search/send, to differentiate if the pattern is meant to be sent or searched to/from the target terminal
