# Integration tests: build an isolated Docker image per benchmark and run a
# 1-episode smoke eval. Each benchmark gets its own image so incompatible
# dependency trees (e.g. hf-libero vs metaworld==3.0.0) can never collide.
#
# To add a new benchmark:
# 1. Add docker/Dockerfile.benchmark.<name> (install only lerobot[<name>])
# 2. Copy one of the jobs below and adjust the image name and eval command.
