Do not use simplistic testing with the problems of persistence - each test job needs to start with a clean setup, not whatever was left behind by a previous test job. Please explain in more detail what you are actually trying to achieve. The test writer can already choose to install (i.e. deploy) and then test - the test job specifies deploy, boot and test actions. *If* the test writer knows that it is then safe to run other tests, those can be added into another job by extending the list of test definitions used by the action. Not all device-types support rebooting the device between test actions in the same test job.

There is no definitive answer to your question.

Some problem I met in Setting up CI environment using Lava2

by Chenchun (coston)

Hi all Problem 1: I find Lava2 re-download Test case repository if more than two test suite needed test in a lava job. Personal think this is waste of time. How can I make lava download Test case repository only once in a lava job ( ps : all of our test suite in some repository) .I want to know lava can do or cant not do, if can please tell me how to do THX. Problem 2: As all we know lava must install os before execute the test task in standard procedure. But in our practical application we find no need mechanical implementation of the Process. In some case, we just need install os only ones and repeated test, even we install manually os and just use lava to do test. We want lava2 like M-lab install os and execute test task uncoupling. we met the problems : can not judge the os installed in DUT(device under test ) whether is our SUT(system under test). All caused by very little information can we read from DUT. I want to know how can I uncoupling install system and execute test ,user can choose only install os 、only execute test 、install os and execute test 、install os ones and repeat execute test ... problem 3: According to your experience, optimally how many DUT can mount under a lava worker and what is a constrain bottleneck?

[Lava BBB01 health check problems?!] Wrong Ramdisk Image Format - Ramdisk image is corrupt or invalid

Hello Folks, Long time no see. Seems that I am back (for limited time) to Lava testing, and after all the setups and catches 22, I managed to get to the bottom of it, within few days.

How to handle reboots within tests

by Tim Jaacks

Hello everyone, I have two cases in which I need to reboot my device during tests: 1. Reboot is active part of the test (e.g. store some persistent settings, reboot, check if persistent settings are correctly loaded after reboot) 2. Reboot is triggered and has to be evaluated (e.g. activate watchdog, stop resetting it, wait, check if system reboots automatically) How can I hadle these two cases in LAVA?

question about result parse pattern in monitor action

NFS mount failures on Debian stretch

by Matt Hart

Hi all, For the boards I am using in my LAVA lab, if I try an NFS job on my jetson-tk1, it fails to mount the filesystem from the debian installed NFS server. http://lava.streamtester.net/scheduler/job/120050 my nfs-kernel-server version is 1:1.3.4-2.1, which was installed with LAVA from Debian Stretch. If I add 'vers=3' to the kernel NFS command line, it mounts the filesystem successfully. http://lava.streamtester.net/scheduler/job/120049 This is being discussed here to make it a default option https://review.linaro.org/#/c/25666/ But really this does seem like there's an issue with the NFS kernel server in Debian Stretch. Has anyone else had this issue? Matt
