# Volt Hybrid Integration Tests — Manifest Validation
|
||||
#
|
||||
# Tests manifest parsing, validation, and behavior:
|
||||
# 1. Valid manifest → successful create
|
||||
# 2. Invalid manifest (missing name) → clear error
|
||||
# 3. Invalid manifest (missing type) → clear error
|
||||
# 4. Manifest with kernel config → verify kernel used
|
||||
# 5. Manifest with resource limits → verify limits applied
|
||||
# 6. --dry-run → no resources created
|
||||
#
|
||||
# Manifests are TOML files in test-manifests/.
|
||||
# The volt CLI reads these when invoked with --manifest or -f flag.
|
||||
#
|
||||
# Requires: root, systemd-nspawn, base image
