Acceptance Criteria

  • AC1: t/ui/10-tests_overview.t is consistently stable within circleCI

Suggestions

  • rrichardson saw this failing at least twice once in post-merge CI checks
  • Try if this can be reproduced at all with a reasonably sized sample size, otherwise reject

This ran on commit https://github.com/os-autoinst/openQA/commit/817cdacb160d2536e08764a6e5fac08e3d08b756 so changes to that test were moved out after and https://github.com/os-autoinst/openQA/commit/25b7bc0c8c99c18fd1a5466048058b2ad4907beb has already been merged. So it seems like this should have been working, indeed.

rrichardson saw this failing at least twice in post-merge CI checks

i was wrong here, the second failure i saw was unrelated. So happened only once so far.

So far

## count-fail-ratio: Run: 1056. Fails: 107. Fail ratio 10.13±1.82%
## mean runtime: 75798±239710.30 ms

but failures that I found are due to temporary decrease of performance of the VM causing timeouts. Running again with

Now fails persistently with

Could not obtain new session: session not created

will trigger a reboot. Reboot helped. Another 584 runs without failure. That is a computed failure probability < .51%
