The deb-install suite sent the output of its runtime image build and of its container start to /dev/null, so a registry timeout or a container that was never created surfaced only as "runtime build failed" with the cause thrown away. The dns-resolver suite already captured that output and printed it on failure. Move its capture helpers into testing/lib/image-build.sh and use them in both suites, so a failed build or start in deb-install prints what docker said. The dns-resolver change is a move only. Also correct the deb-install header, which still described the package build it no longer does itself.

# Test fips-dns-setup across different Linux resolver backends, plus
|
|
# an end-to-end scenario that verifies a real fips answers .fips
|
|
# queries through the configured backend.
|
|
#
|
|
# Each scenario runs a systemd-based Docker container, creates a dummy
|
|
# fips0 interface (or a real one for the e2e scenario), runs the setup
|
|
# script, verifies the detected backend and generated config, runs
|
|
# teardown, and verifies cleanup.
|
|
#
|
|
# The end-to-end scenarios take fips and fips-gateway from the Debian
|
|
# package, which is built in the pinned floor container and so runs on
|
|
# every target distro. Each starts the daemon, configures DNS via the
|
|
# script, and confirms `dig @127.0.0.53 AAAA <npub>.fips` returns a
|
|
# non-empty AAAA answer.
|
|
#
|
|
# Usage: ./test.sh [--deb PATH] [scenario ...]
|
|
# --deb PATH = take the binaries from this package. Without it the
|
|
# e2e scenarios build the package through
|
|
# packaging/debian/build-deb-container.sh.
|
|
# No scenarios = run all scenarios.
|
|
# Named scenarios = run only those (e.g., ./test.sh debian12-resolved e2e-debian12)
|
|
#
|
|
# Requirements: Docker able to grant SYS_ADMIN and NET_ADMIN and an
|
|
# unconfined AppArmor profile (the containers are not privileged; see
|
|
# testing/lib/systemd-container.sh). The e2e scenarios also need
|
|
# /dev/net/tun on the host (standard) and dpkg-deb to read the package.
