* Each test runs in its own process and checks for pass fail and appends to /tmp/fail.log |

* If any test fails it outputs a fail report into a 'fail.log'. Top level script watchs for items in /tmp/fail.log and if found aborts the runin early. Then copies the /tmp/fail.log and rundone.fth to /bootpart/runin. |

Revision as of 04:29, 18 June 2012
olpc-runin-tests is a collection of tests for the XO-1.5 and XO-1.75 that are run during late stages of laptop production.
(It might also be useful for in-field diagnostics. It is designed to test the hardware as well as the software installation, but is not designed to cover all software functions. The software testing is not intended to discover and report software failures, since these would unnecessarily interrupt production. Care should be taken not to use it for software testing without understanding the limitations.)
By default, the tests are run in a loop for several hours. If any test fails at any point, the system is shutdown.
Logs are written to /runin/logdir, which is later packed into a .tar.gz. fail.log is the single log which you can quickly check for success or failure; the file is empty on success.

One-off Test
To repeat the RUNIN tests on a shipped laptop;
touch /runin/force reboot
After the test run, look in /runin/logdir for the output.
If the file /runin/logdir/fail.log is present and contains text, then the test run failed.
Repeating Tests
At the firmware ok prompt, set the TS manufacturing tag to RUNIN:
ok delete-tag TS ok add-tag TS RUNIN
Boot the system as normal, and instead of the normal boot routine, the runin tests will kick in.
When done, use the ok prompt to reset the TS tag to SHIP:
ok delete-tag TS ok add-tag TS SHIP
Kernel Suspend and Resume Stability Testing
Runin is being used for testing stability of suspend and resume. See XO-1.75/Kernel/Runin.
