# The image the add-on's tests run in (CI-01). This repo had NO CI at all before
# that ticket - eight runnable test files, none of them ever run by a machine.
#
# ⚠️ THE DEPENDENCIES ARE THE SHIPPED ONES, FROM APK, AND THAT IS THE POINT.
# goodwe_controller/Dockerfile installs `py3-aiohttp py3-paho-mqtt` from Alpine
# packages rather than pip, because Alpine ships musl and there are no musl
# wheels for aiohttp - pip would compile it from source on a client's Raspberry
# Pi. Testing against pip-installed glibc wheels would be testing a different
# add-on from the one that ships. Same base, same package manager, same names.
#
# ⚠️ NOT `FROM ghcr.io/home-assistant/...-base`. The real Dockerfile takes its
# base from the Supervisor's `BUILD_FROM` build-arg, which is per-architecture
# and not resolvable outside a Supervisor build. `alpine:3` is what those images
# are, minus the s6 supervision the tests do not use - and it is already cached
# on this runner's host, so the gate does not depend on a registry pull.
#
# ⚠️ The runner container itself CANNOT run these tests: it is Alpine with a bare
# python3, no aiohttp, no pip (`No module named pip`; checked on the box, not
# assumed). An image is not gold-plating here, it is the only option that does
# not mutate a shared long-lived runner.
# ⚠️ `git` IS A TEST DEPENDENCY, NOT A CONVENIENCE (CI-02). test_ci_gate.py
# grades the gate's own checkout by EXTRACTING the shell out of
# .gitea/workflows/checks.yml and RUNNING it - against two throwaway local
# repositories it builds itself, one whose pull request merges and one whose
# does not. Reading those commands as a string would be the thing this
# repository keeps finding: a check that never observed its subject. Running
# them needs git in the image the checks run in.
#
# It costs one apk package and no network at test time: the fixtures are local
# paths, and the token substitution in the workflow's `git remote add` is a
# no-op on a path with no `://` in it, which is exactly why the test can use
# the shipped line verbatim instead of a paraphrase of it.
