Possibly something that ome/omero-test-infra#60 could solve by invoking pytest directly?

[will-moore]

The workings of omero-test-infra are a bit confusing so I don't know the answer to that. Why are no other repos affected by this issue?

[sbesson]

Pretty certain this is the result of this being one of the few OMERO plugins to use setuptools_scm (which internally writes the version) - see https://github.com/search?q=org%3Aome+setuptools_scm&type=code.

I think the current logic is that the installation command is executed as root in but the test command is executed as the local user. I cannot comment on the impact of modifying this assumption.
