container-structure-test left one anonymous volume per test container. tests/structure.py runs it with --save and removes the new containers with their volumes afterwards. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

"""Run container-structure-test without leaking Docker volumes.
|
|
|
|
container-structure-test starts one container per test and never removes it. The image
|
|
declares `VOLUME /data`, so every container drags an anonymous volume along that outlives
|
|
`docker rm`. With `--save` the containers are kept, and this wrapper removes the ones the
|
|
run created, together with their volumes (`remove(v=True)`). Run with `task test:structure`.
|
|
|
|
Exit code: the one of container-structure-test.
