Add end-to-end testing against real Home Assistant - #423
Conversation
The bugs that reach users are rarely wrong values. They are entities that look correct in the code and make Home Assistant log on every message — issue #346, then #418, which only appeared on installations that already had the entity. Nothing in the suite could see either: they are about what Home Assistant does with a discovery message, not about what hm2mqtt computes. Three layers, cheapest first. The discovery baseline records every message hm2mqtt publishes, per device type, as a file. Its diff shows what a change does to the entities users get. It is generated from the state a device fixture parses into, and the same fixture is what the simulator replays to the real build, so the baseline describes exactly the entities an end-to-end run creates. A rule compares the baseline against the last release: an entity that keeps existing but loses its state topic fails the unit suite, naming #418. That is the whole lesson of that issue, enforced without booting anything. Two end-to-end scenarios run the shipped build against Home Assistant 2026.2.3, an aedes broker and three simulated devices. The smoke scenario starts from nothing; the upgrade scenario seeds the previous release's retained discovery first, so Home Assistant applies the new messages to entities that already exist — the code path #418 lived in. Both assert that Home Assistant logged no complaint, which is the assertion the two issues would have failed. The suite is separate from `npm test`, needs no Python to skip cleanly, and caches its Home Assistant install in CI. It found three live findings on the way in: *WiFi Signal Strength* on the B2500 V2 and *Local API Enabled*/*Local API Port* on the Venus read values their device declares but does not always send, so their templates render against a payload without them. They are recorded as known findings in the scenarios, and anything new fails.

The setup-python pin was not a real commit, so the job died while resolving actions, one second in and before any step ran. Both new pins are now the commit each release tag points at.
ts-jest 29.4 deprecated its own `isolatedModules` option in favour of the compiler one, and warned about it on every run of both suites. Moving it to tsconfig.json is what the warning asks for and changes nothing about how tests are compiled. The scenarios skip when Home Assistant is not installed, which is right on a developer machine and wrong in CI: a skipped scenario reports success and proves nothing. They now fail there instead.

The wait for "the new build republished discovery" was satisfied before hm2mqtt even started. The scenario seeds the previous release's retained messages through the same probe that observes them, on the very topics the new build uses, so the topic set was already full. It now marks the broker's publish history before starting hm2mqtt and waits for a fresh discovery publish per configured device. Also from the review: - waitFor kept retrying into its timeout after a managed process had exited. A probe can now abandon the wait, so a dead Home Assistant fails in seconds with its log instead of after three minutes. - The simulated device's response promise was unhandled, which during teardown could fail an unrelated test; failures are recorded instead. Its client id no longer truncates, which could collide for two devices of one type. - Home Assistant's teardown waits for the process to go after SIGKILL, rather than handing the next scenario a process still holding the config directory. - Escaped the device type before building the substitution pattern, the stale log-scan comment, a duplicated baseline reader, the misplaced Node requirement in AGENTS.md, and a fence language. Not changed: flattening a fixture's parsed messages with Object.assign mirrors DeviceManager.getDeviceState, which reduces its per-path state the same way, so the baseline sees the state the runtime would.

Worked through the review in The major one was right, and it mattered. The upgrade scenario's wait for "the new build republished discovery" was satisfied before hm2mqtt even started: the scenario seeds the previous release's retained messages through the same probe that observes them, on exactly the topics the new build uses, so the topic set was already full. The scenario was asserting on Home Assistant's log without having confirmed the upgrade had happened at all. It now marks the broker's publish history before starting hm2mqtt and waits for a fresh discovery publish per configured device, so the assertion runs against a real upgrade. Verified: the suite still passes, which means hm2mqtt genuinely does republish — previously untested. Also fixed:

Both harness components sent SIGKILL and returned without checking. A process that survived would run against the broker while the next scenario started, and the run would still report success. Teardown now waits for the exit and fails if it never comes — the Stack collects teardown failures, so the run says so instead of quietly overlapping. hm2mqtt also handles the case where the process never starts: spawn reports that as an `error` event without an `exit`, which the readiness wait would have sat through until its timeout.
