Add hack/check-host-runtime.bats with six self-contained test cases that exercise the check-host-runtime.sh preflight script: clean host exits silently, standalone containerd.service warns, standalone docker.service warns, both services warn, du failures do not suppress warnings, and the socket-only fallback fires when systemctl is unavailable. Tests inject a stub systemctl and du binary via PATH and redirect the script's probe paths through COZYSTACK_PREFLIGHT_* environment variables, so they run without root and on any host (including non-systemd macOS).

|
# Unit tests for hack/check-host-runtime.sh
|
|
#
|
|
# The script warns when a standalone containerd.service or docker.service is
|
|
# active alongside the embedded k3s runtime on Ubuntu hosts running the
|
|
# cozystack "generic" variant. Warnings go to stderr; exit code is always 0.
|
|
#
|
|
# Test strategy: each test builds its own temporary stub directory and prepends
|
|
# it to PATH to inject a fake `systemctl` (and optionally `du`) binary. The
|
|
# script itself honors a small set of COZYSTACK_PREFLIGHT_* environment
|
|
# variables to redirect socket/dir probes into the stub tree, so tests do not
|
|
# need root privileges or a real systemd host.
|
|
#
|
|
# Tests are self-contained — no shared setup/teardown helpers, because
|
|
# cozytest.sh's awk parser only recognizes @test blocks and treats a bare `}`
|
|
# on its own line as the end of a test function.
|
|
#
|
|
# Run with: hack/cozytest.sh hack/check-host-runtime.bats
|
|
# (or `bats hack/check-host-runtime.bats` if the bats binary is
|
|
# installed; cozytest.sh is the CI path.)
