didericis d0d1da612e refactor(firecracker): split the combined rootfs into per-plane artifacts
Each infra VM now boots its own rootfs instead of a shared combined image, so
the exposed gateway VM no longer carries buildah + the control-plane code it
never runs (a fatter, less-isolated exposed surface — the opposite of the plane
split's intent). The combined image bought only "one artifact"; each VM already
kept a full copy of the shared rootfs, so nothing was saved at boot.

  * orchestrator rootfs — control plane + buildah (Dockerfile.orchestrator.fc,
    FROM orchestrator); the slim gateway rootfs boots bot-bottle-gateway:latest
    directly. Dockerfile.infra.fc (the combined image) is deleted.
  * `_infra_init` splits into `_orchestrator_init` / `_gateway_init` (shared
    preamble via `_init_head`); each per-plane rootfs bakes only its role init,
    so the `bb_role` cmdline branch is gone.
  * infra_artifact is role-parametrized: a per-role package
    (bot-bottle-firecracker-<role>), version hash, URL, cache dir, and candidate
    subdir. `ensure_built` pulls both; `_expected_version` combines both markers.
  * publish_infra builds the images once, then builds + publishes an
    orchestrator and a gateway artifact under DIR/<role>/.

coverage.sh's candidate-dir plumbing is layout-agnostic (publish_infra --output
now fills DIR/<role>/, which ensure_artifact_gz reads). Full suite green.

Tests

Plain-Python test suite using stdlib unittest. No external dependencies. Unit tests run anywhere Python 3 is present; integration tests run through the backend named by BOT_BOTTLE_BACKEND (default docker) and skip cleanly when that backend isn't available on the host.

Layout

tests/
  fixtures.py                       # JSON manifest builders (shared)
  _backend.py                       # backend selection + skip guards (shared)
  unit/
    test_egress.py
    test_egress_addon_core.py
    test_manifest_egress.py
    test_dlp_detectors.py
    test_manifest_runtime.py
    ...                             # many others; see unit/ directory
  integration/
    test_gateway_image.py
    test_dry_run_plan.py
    test_orphan_cleanup.py
    ...
  canaries/                         # opt-in; see below (currently empty)

Classification falls out of the directory — no hand-maintained list to keep in sync.

Running

python -m unittest discover -t . -s tests/unit -v         # unit only
python -m unittest discover -t . -s tests/integration -v  # integration only
python -m unittest discover -t . -s tests -v              # both (recursive)
python -m unittest tests.unit.test_manifest_egress        # one file

Discovery is invoked with -t . (top-level dir = repo root) so the bot_bottle package on sys.path resolves correctly.

What the integration tests cover

  • test_dry_run_plan.pycli.py start --dry-run --format=json emits a structured plan that contains the resolved egress allowlist and the bottle's runtime, and creates zero Docker resources.
  • test_orphan_cleanup.pynetwork_remove is idempotent against missing resources, so the EXIT trap can call it unconditionally.
  • test_gateway_image.py — builds Dockerfile.gateway and probes that gitleaks / mitmdump / supervise are all reachable inside the gateway image.

Canaries

tests/canaries/ holds upstream-regression checks gated on BOT_BOTTLE_RUN_CANARIES=1 and not part of the per-push suite. They're invoked by the scheduled canaries workflow. Currently no canaries are defined.

BOT_BOTTLE_RUN_CANARIES=1 python -m unittest discover -t . -s tests/canaries -v

What's NOT covered

  • bot_bottle/ssh.py end-to-end (would need a fake SSH host inside the container).
  • A live SSH-through-git-gate tunnel against a real Tailscale-style IP.
  • DLP false-positive measurements.
  • TLS handling / cert pinning behavior.

Adding a test

  1. Pick the directory: tests/unit/ for a pure unit test, tests/integration/ for one that needs a backend.

  2. Filename: test_<topic>.py.

  3. Boilerplate:

    import unittest
    
    from bot_bottle.<module> import <symbol>
    
    class TestThing(unittest.TestCase):
        def test_x(self):
            ...
    
    if __name__ == "__main__":
        unittest.main()
    
  4. Skip guards live in tests._backend and gate on the backend's own readiness check, bot_bottle.backend.has_backend — the same probe behind ./cli.py backend status:

    • Backend-agnostic tests (go through get_bottle_backend()) decorate the class with @skip_unless_selected_backend_available() — the test runs against whichever backend BOT_BOTTLE_BACKEND selects and skips unless that backend is available (checking, e.g., Linux + /dev/kvm for Firecracker rather than unrelated Docker availability).
    • Backend-specific tests (exercise DockerBroker, DockerGateway, backend.docker.*, …) decorate with @skip_unless_backend("docker") so they no-op under a run targeting a different backend.

    Each CI integration job runs ./cli.py backend status --backend=<name> as a preflight, which prints a clear per-check summary and exits non-zero when the backend is missing — so absent infrastructure fails the job instead of hiding among per-test unittest.skip lines.
