Two new functional tests: +n8n's characteristic behavior is **a working REST API on top of a working workflow engine**. /healthz +returns 200 long before the actual n8n process is ready — the REST endpoints serve a placeholder +HTML page ("n8n is starting up. Please wait") with status 200 during early boot. So a meaningful +n8n-specific test must distinguish "the HTTP layer answers" (what generic+install does) from "the +n8n REST API actually responds with JSON". Two new functional tests: | cc-ci file | what's verified | rationale | |---|---|---| -| `tests/n8n/functional/test_node_types_catalog.py` | Fetches `/types/nodes.json` and asserts the response is a JSON list, contains a meaningful number (>= 50) of node-type definitions, and includes specific n8n-built-in node names such as `n8n-nodes-base.set`, `n8n-nodes-base.if`, and a webhook/HTTP node — proves the n8n runtime bootstrapped its **node registry** (the workflow engine's core capability), not just "the HTTP server is up". | The node registry is what makes n8n n8n; an n8n that boots but loads no nodes is broken. | -| `tests/n8n/functional/test_rest_settings.py` | Fetches `/rest/settings` and asserts the JSON response carries the expected n8n public settings keys (e.g. `data.endpointWebhook`, `data.versionCli`) — the public settings surface is what every editor SPA loads to bootstrap, and proves the n8n REST API initialized + the SPA can talk to it. | Proves the editor SPA's primary API contract is intact — distinct from "/" returning HTML, which only proves a static asset was served. | +| `tests/n8n/functional/test_rest_settings.py` | Polls `/rest/settings` until the response is **application/json** (not the SPA "starting up" placeholder) AND the JSON envelope carries known n8n public-settings keys (e.g. `endpointWebhook`, `versionCli`, `n8nMetadata`, `instanceId`). | This is the API the editor SPA literally calls to bootstrap — if n8n boots but cannot serve its public settings, the UI is dead. Non-vacuous: a placeholder-HTML response (boot still in progress) is rejected; a JSON response that's the wrong shape is rejected. | +| `tests/n8n/functional/test_login_state.py` | Polls `/rest/login` until the response is **application/json** (auth subsystem responded) and the body is a JSON dict/list — proves the user-management layer initialized on top of the public-settings surface. | Distinct from `test_rest_settings`: this tests the auth subsystem specifically. A broken auth backend would let `/rest/settings` return JSON but `/rest/login` would 5xx or stay as the placeholder. | Both tests run in the **custom** tier against the same `live_app` shared deployment as the lifecycle overlays — no extra deploy, no extra teardown. diff --git a/tests/n8n/functional/test_health_check.py b/tests/n8n/functional/test_health_check.py new file mode 100644 index 0000000..df74cfc --- /dev/null +++ b/tests/n8n/functional/test_health_check.py @@ -0,0 +1,23 @@ +"""n8n — parity port of recipe-maintainer's health_check.py (Phase 2 P2). + +SOURCE: references/recipe-maintainer/recipe-info/n8n/tests/health_check.py + +The original asserted HTTP 200 from `https://n8n.`.
