[CI]: Tracking status #3577
Description
With the current effort on testing, we should start looking into our run duration, platform coverage, and hard data on flakyness / disabled tests.
This issue here is to record that information over time.
This is the first sample (of #3535), ran on 10/19/2024

Current take-aways:
- arm is significantly slower - either the machine we are using is not big enough, or it is emulated, or github offering is not really good...
- build time overall is consistent - at 4 minutes though, we should be able to cut that to 1 minute or less (implies rethinking the way we build the image and possibly push the "dependencies" part on a registry instead of rebuilding them every time)
- windows testing is really weak, with 100 safe tests, and 100 flaky tests
- we now have about 300 safe tests (not counting ipv6 and kube), and about 650 "flaky" tests - so, about 1/3 are considered safe - when the
containertests suite will be done, the balance should shift towards 50% - for the worst offenders:
- TestCopy are very slow - current in-progress rewrite will parallelize and reduce this
- Compose tests are definitely the number 1 contributor (including some IPFS tests) - we should look into this and figure out why compose is so slow
- current flakyness status
- 2 failed runs out of the 8 main target platforms (with 4 test failures) - these are both
TestIPFSCompNoBuild- the issue being likely [MAJOR] content digest not found #3513 (it might be a snapshotter issue though, and not a nerdctl one) - 4 "rewritten" tests are explicitly flagged as flaky (3 on windows, 1 on IPFS)
- 9 tests are currently disabled (marked
NerdctlNeedsFixing), although some of them might have been fixed recently - they should be reviewed

Will post other samples on this ticket in the future to track progress.

I wish we could automate data collection and have some graphs generated automatically.
