I'm trying to add fchown function to the fslib module, but my new test doesn't work on ci runner, the chown command seems to require higher privileges, but ci runner is just a normal user. (a related discussion: https://github.com/orgs/community/discussions/26717

I'm not quite sure how to solve this problem, can anyone help me?

I'd go with dropping the test in this instance, since they are difficult to implement in a portable way. Alternatively we could check whether the chown fails with the right error message, but it might not work everywhere either 😕

Thanks for the reply.

Ok, I deleted the test and rebase the branch onto master.
