Hi,
I have been investigating LAVA for use in our organisation and i'm stuck trying to get a hello world test case running on our hardware and looking for some help. We looked at the YOCTO test tools however it can only use devices with a fixed ip which we can't guarantee or want during our testing as we also test network settings. It's also limited in configuration, LAVA package seems to meet all our requirements however i'm still unsure on how to do a few things.
We use Yotco images and boot with the grub bootloader.
All our devices are connected via Ethernet only and power and peripheral switching is controlled via usb relays.
After reading through all the documentation i'm still unsure of how to set up and actually run a test on our hardware. What tools do i need to install in the test image and how do i get it to communicate with grub? I assume a base image is one that includes nothing but the tools and grub. We have a recovery partition with tiny core which could facilitate that but it's not required for the automated testing.
I've used the akbennet/lava-server docker image and it is up and running, although test jobs are scheduled but never run on the qemu devices so a little stuck there.
Basically, I need help to get LAVA to connect to one of our devices to load the image and run tests?
Choosing the image, writing tests and mostly configuring the pipeline I understand.
After 2 weeks i'm posting here hoping someone can assist me.
Regards,
Elric

Hi All,
I am trying to setup a remote lab using Raspberry pi on my local network.
I installed lava-server and a worker on my laptop and its working fine.
I installed raspbian on R-Pi and follow the instruction given on lava site,
but when slave is trying to connect to master its not getting any response,
I am able to ping master from my R-pi board and default port 3079 is open
on my machine.
I used no encryption and use URL to connect master as follow.
MASTER_URL="tcp://10.42.0.24:3079"
LOGGER_URL="tcp://10.42.0.24:3079"
I continuosly getting log messgaes like,
DEBUG Sending new HELLO_RETRY message to the master (are they both running
the same version?)
INFO Waiting for the master to reply
DEBUG Sending new HELLO_RETRY message to the master (are they both running
the same version?)
INFO Waiting for the master to reply
DEBUG Sending new HELLO_RETRY message to the master (are they both running
the same version?)
Please, if any one have some idea why I am not able to connect please help.
Thanks,
Ankit

Running the build tests within the Jenkins build makes a lot of sense.
Typically, the build tests will have a different command syntax to the
runtime tests (otherwise Jenkins would attempt to run both), so
filtering should be possible. If the build tests are just a different
set of binary blobs from the runtime tests, that may need a fix
upstream in Zephyr to distinguish between the two modes.

Yes, LAVA has support for pass, fail, skip, unknown.
For POSIX shell tests, the test writer just calls lava-test-case name
--result skip
For monitor tests, like Zephyr, it's down to the pattern but skip is as
valid as pass and fail (as is unknown) for the result of the matches
within the pattern.

There are known limitations with the USB subsystem and associated
hardware across all architectures, affecting test devices and the
workers which run the automation. LAVA has to drive that subsystem very
hard for both fastboot devices and IoT devices. There are also problems
due to the design of methods like fastboot and some of the IoT support
which result from a single-developer model, leading to buggy
performance when used at scale and added complexity in deploying
workarounds to isolate such protocols in order to prevent interference
between tests. The protocols themselves often lack robust error
handling or retry support.
Other deployment methods which rely on TFTP/network deployments are
massively more reliable at scale, so comparing reliability across
different device types is problematic.

LAVA result handling is ultimately a pattern matching system. Patterns
must have a unique and reliable start string and a unique and reliable
end string. An empty start string is just going to cause misleading
results and bad pattern matches as the reality is that most boards emit
some level of random junk immediately upon connection which needs to be
ignored. So there needs to be a reliable, unique, start string emitted
by the test device. It is not enough to *assume* a start at line zero,
doing so increases the problems with reliability.

That will need code changes, so please make a formal request for this
support at CTT
https://projects.linaro.org/servicedesk/customer/portal/1 so that we
can track exactly what is required.

That JIRA story is in the LITE project. Nobody in the LAVA team can
manage those stories. It needs a CTT issue which can then be linked to
the LITE story and from which a LAVA story can also be linked.
Sadly, any story in the LITE project would go completely unnoticed by
the LAVA software team until it is linked to CTT so that the work can
be prioritised and the relevant LAVA story created. That's just how
JIRA works.

My simple tests are running now thanks to the help of the nice people
from the #linaro-lava chat.
1) Crazy me decided to use upstream u-boot 2017.05 instead of running
some ancient version from 2014;)
1.1) which happens to have a different AUTOBOOT_PROMPT than the one Lava
expects "Press SPACE to abort autoboot in %d seconds\n" instead of "Hit
any key to stop autoboot" so (since) I would like to be able to stay as
close as possible to upstream LAVA 2017.06 I patched u-boot[1]. Note
that this could be fixed with LAVA as well - interrupt_prompt: {{
interrupt_prompt|default('Hit any key to stop autoboot') }}
1.2) also the SYS_PROMPT of upstream u-boot is different than the one
expected by LAVA and again I made a u-boot patch[2]. Note that this
could be fixed with LAVA as well - {% set bootloader_prompt =
bootloader_prompt|default('U-Boot') %}
2) After some searching it turned out that LAVA set some funny variables
in u-boot which made my kernel crash. (Crazy me decided to use a 4.9.x
uImage without baked in address).
Adding this:
{% set base_high_limits = false %}
to my bbb03.jinja2 file fixed it.
... obviously ;)

Hello Milosz,
Thanks for routing this thread to lava-users - when I made initial post
to linaro-validation, I check my archive and so that e.g. Neil posts
there frequently, but I missed that it's not official LAVA list.

Hmm, I wonder what would be criteria for being "failed" for such
tests... Anyway, thanks for sharing - I'm not familiar with all Zephyr
tests/samples myself, will keep in mind such issues when looking into
them.

Matt Hart actually showed me a ticket on that, so at least it's
confirmed/known issue in works. But even with arduino_101 and
frdm_k64f, I hit cases more than once when board(s) were stuck for
extended time, but still were routed jobs to (which either failed or
timed out). So, there may be problem with health checks, which either
don't run frequently enough or aren't robust enough. arduino_101 is all
the lone one, so if something happens to it, there's no backup. Etc,
etc.

Well, that would require bunch of legwork, but the biggest problem is
that it wouldn't test what's actually required. E.g. both JerryScript
and MicroPython Zephyr ports are actually interactive apps working over
serial connection. And functional testing of them would be feeding
something over this serial connection and checking that results are as
expected. I'll keep in mind idea of "builtin" tests though.
Thanks!

Hello LAVA experts,
I am currently working with LAVA and was asked to find is there a way to get data from device dictionary inside a running job. Details like below:
I have a device name demo-01, and its device-dictionary have one line like "{% set my_property = 'my_prop' %}". Then I have a job running on demo-01 device, and I would like to use string 'my_prop' to passed into a script during running. Is it possible to get device-dictionary data directly from job definition(Job Submitter webpage) or test definition(yaml file)? If yes, how could I do this? If not, is there any good way you would like to share to solve this problem?
Thanks and Best Regards,
Yifan
Hi all,
