The LAVA software team created a document to summarise the experience, so far, of automating devices for validation and that document formed the basis of a presentation at Linaro Connect in Hong Kong earlier this year by Steve McIntyre. The content has been living inside a wiki within Linaro but there have been delays in making the URL visible to anonymous viewers. I have therefore migrated the content to my blog: https://linux.codehelp.co.uk/automation-and-risk.html A link to the presentation is included. Available under CC BY-SA 3.0 and shortly to appear on planet.debian.org Please share with anyone involved in designing hardware which is likely to end up on your desk for automation support and anyone else who may be interested in the hardware challenges of device automation. A second shorter post on Firmware Best Practices will follow - some of the elements of that document were also covered in the presentation at Connect. -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

[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?

Refer to https://validation.linaro.org/scheduler/job/1807112 test_po test_poll_ test_poll_mu I also tried the following patterns, but no lucky. '(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)$’ matched sth similar as above, but the not the same. Refer to https://validation.linaro.org/scheduler/job/1807117 '(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)\n’ didn’t match anything. A search online hit https://stackoverflow.com/questions/14689531/how-to-match-a-new-line-charac… . Then I tried manually in python shell. '(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)’ works, '(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)$’ works only when re.M enabled. — debug — >>> s "\nTrying ::1...\nConnected to localhost.\nEscape character is '^]'.\nFRDM-KW41Z-01 7113 [115200 N81]\n***** Booting Zephyr OS v1.11.0-1194-g4b0b65c1b *****\nRunning test suite poll_api\n===================================================================\nstarting test - test_poll_no_wait\nPASS - test_poll_no_wait\n===================================================================\nstarting test - test_poll_wait\nPASS - test_poll_wait\n===================================================================\nstarting test - test_poll_multi\nPASS - test_poll_multi\n===================================================================\n===================================================================\n" >>> p.search(s).group() 'PASS - test_poll_no_wait' >>> p = re.compile(r'(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)$') >>> p.search(s).group() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'NoneType' object has no attribute 'group' >>> p = re.compile(r'(?P<result>(PASS|FAIL))\s-\s(?P<test_case_id>\w+)$', re.M) >>> p.search(s).group() 'PASS - test_poll_no_wait’ — ends — Could you please advise me how to handle the parsing with the monitor action? Thanks, Chase
