Adding time.timeZone = "UTC"; here will eliminate ugly time zone warnings from the test log.

I'm not able to find these warnings. Could you paste an example? Are they in the nix-build output or in the generated html test log?

Ok, fixed thanks (this is only visible with sandboxed builds).

The test seems non-deterministic on my local machine: it succeeds the first time but then fails on repeated runs, because the jobset is unchanged and skipped by hydra, so it waits here until the waitUntilSucceeds times out .
You could fix this by artifically changing the derivation hash of the trivial derivation on every test run, for instance by making some attribute depend on current time or a random value.

It is also sometimes failing on my machine... When it fails, in the test log, there is:
machine# [ 47.021598] hydra-queue-runner[1167]: marking build 1 as failed
And the log of the build is:
<3>builder for '/nix/store/nfmhzq2sv51qn1mh0lfmkpiwpk8dc2v5-trivial.drv' failed due to signal 9 (Killed)
But the output path has been produced even if the job is marked as failed. It seems this is related to Hydra and not to Nix.
Note also if I restart the job, it succeeds...

@xeji I've fixed the non deterministic issue I encountered. Could you try again?

Thanks, non-deterministic failure seems gone here too. Looks good now.

For the non deterministic failure, see NixOS/nix#2176. |
A script is used to create a project, and configure a jobset. This jobset fetches a local file containing a trivial Nix expression. The test script makes sure this derivation has been successfully built by Hydra.
