Subject: [PATCH 1/8] feat(e2e): add cluster-free local E2E harness (legacy
 Tier B + app-next)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Run real Playwright E2E against RHDH without an OpenShift/Kubernetes cluster
or container images — Playwright boots the backend and a frontend dev server
in-process and drives the browser against them.

- Legacy harness (Tier B, recommended): targets packages/app with dynamic
  plugins loaded via Scalprum, so the EXISTING specs run unmodified. Verified
  the production RHDH home page (Quick Access from the dynamic home-page
  plugin) renders off-cluster and the guest-signin home-page test passes.
- app-next harness: targets the new frontend system; covers core/statically
  registered plugin UIs (dynamic frontend loading is blocked upstream — see doc).
- Shared guest-auth + in-memory-SQLite overlay (app-config.local-e2e.yaml);
  webServer invokes backstage-cli/janus-cli from the repo-root .bin.
- yarn scripts: e2e:legacy-local, e2e:app-next-local.

Part of RHIDP-13501 (E2E Test Optimization), Layer 4a spike RHIDP-15075.

+# Cluster-free local E2E harness
+
+Spike deliverable for **RHIDP-13501 — E2E Test Optimization (Layer 4a)**, building on
+the PoC in [PR #4523](https://github.com/redhat-developer/rhdh/pull/4523) and the
+backend dynamic-plugin loader from RHIDP-13508.
+
+## Goal
+
+Run real Playwright E2E against RHDH **without** an OpenShift/Kubernetes cluster or
+container images — a single `run` that boots the backend and a frontend dev server
+in-process and drives a browser against them.
+
+Two harnesses are provided:
+
+| Harness | Target | Command | Status |
+|---------|--------|---------|--------|
+| **Legacy (Tier B)** | `packages/app` (Scalprum) + dynamic plugins | `yarn --cwd e2e-tests e2e:legacy-local` | Production-faithful; runs the **existing** specs |
+| **app-next** | `packages/app-next` (new frontend system) | `yarn --cwd e2e-tests e2e:app-next-local` | Forward-looking; core app only (see limits) |
+
+Both layer the guest-auth + in-memory-SQLite overlay `app-config.local-e2e.yaml` on
+top of `app-config.yaml`. Guest sign-in must be configured explicitly — the auth
+backend otherwise rejects guest with _"you must … configure the auth backend to
+support guest sign in."_
+
+## Legacy harness (Tier B) — recommended
+
+This is the production-faithful target: it is what RHDH ships today, and **the existing
+Playwright specs already target it**, so they run unmodified. Dynamic frontend plugins
+load through Scalprum exactly as in-cluster (the legacy `scalprum-backend` serves the
+plugin config by default).
+
+### 1. Populate `dynamic-plugins-root` (one-time)
+
+Production-faithful — full plugin set and generated config, the same source CI uses:
+
+```bash
+CATALOG_INDEX_IMAGE=<quay.io/rhdh/plugin-catalog-index:TAG> \
+  npx @red-hat-developer-hub/cli-module-install-dynamic-plugins install dynamic-plugins-root
+```
+
+Offline alternative (frontend plugins only; requires a reconciled workspace —
+see "Known issues"):
+
+```bash
+yarn --cwd dynamic-plugins export-dynamic
+yarn --cwd dynamic-plugins copy-dynamic-plugins ../dynamic-plugins-root
+```
+
+### 2. Run
+
+```bash
+yarn --cwd e2e-tests e2e:legacy-local
+```
+
+Playwright (`playwright.legacy-local.config.ts`) boots the backend and the legacy app
+dev server with `app-config.yaml` + `app-config.dynamic-plugins.yaml` +
+`app-config.local-e2e.yaml`, then runs the UI specs in `testMatch` that do not require
+live external services.
+
+### Verified
+
+With plugins populated, the legacy app renders the full production RHDH UI off-cluster
+(branding, sidebar, and Quick Access from the dynamic home-page plugin). The existing
+`guest-signin-happy-path` **home-page test passes unmodified** — confirming a dynamic
+frontend plugin renders with no cluster.
+
+## app-next harness
+
+`playwright.app-next-local.config.ts` + `playwright/app-next-local/guest-identity.spec.ts`.
+Boots the backend + app-next dev server with guest auth. Cold start ~17–20s (warm
+rspack cache); ~3s reusing servers; stable; clean teardown.
+
+**Limit — dynamic frontend plugins do not load on app-next yet.** app-next uses
+`dynamicFrontendFeaturesLoader()` → `GET <backend>/<pluginId>/remotes`, served by
+`dynamicPluginsFrontendServiceRef`, which the RHDH backend no-ops unless
+`ENABLE_STANDARD_MODULE_FEDERATION=true` — and even then returns 404 because RHDH's
+exported dynamic frontend plugins do not contain standard Module Federation assets by
+default (see `packages/backend/src/index.ts`). app-next also has no Home page. So
+app-next currently covers core/statically-registered plugin UIs (e.g. user-settings)
+only; the legacy harness is the way to exercise dynamic plugins off-cluster today.
+
+## vs. rhdh-local
+
+[`rhdh-local`](https://github.com/redhat-developer/rhdh-local) runs RHDH via
+Podman/Docker Compose using the **production container image**. It is great for manual
+feature testing with guest auth and UI-installed plugins, but it is **container-based**:
+it requires a container runtime and pulling/running the RHDH image. For fast automated
+E2E it is heavier than this in-process harness (no image pull, no container runtime —
+just `run`), which is why this harness boots the dev servers directly instead.
+
+## Known issues / limits
+
+- **Workspace must be reconciled for the offline (from-source) populate path.** If
+  `node_modules` is out of sync with `yarn.lock` (e.g. just after a rebase that changed
+  dependency versions), backend dynamic-plugin builds fail with version-mismatch errors
+  and yarn may not surface workspace bins. Run `yarn install` first. The
+  `install-dynamic-plugins` populate path avoids building from source and is unaffected.
+- **`global-header` plugin mounting** still needs config sorting for the legacy harness;
+  specs that navigate via the top-right profile dropdown depend on it.
+- **Live-external-service specs** (real k8s cluster, GitHub org, Quay, Tekton, Keycloak)
+  still need those services or mocks; this harness covers UI/plugin-rendering scenarios
+  that don't require live external infra.
+- **`janus-cli` / `backstage-cli`** live in the repo-root `node_modules/.bin`, which yarn
+  does not surface for the `app`/`backend` workspaces, so the webServer commands invoke
+  them directly with the root `.bin` prepended to `PATH`.

Subject: [PATCH 2/8] refactor(e2e): address review on local harness

- Scope legacy testMatch to the spec verified to pass off-cluster
  (learning-path-page); document the others as pending the global-header
  mount fix / per-spec config so the default run is green.
- Guard PATH interpolation against an undefined process.env.PATH via a
  shared pathWithRepoBin constant in both configs.
- Default CATALOG_INDEX_IMAGE to quay.io/rhdh/plugin-catalog-index:latest
  for main (release branches use the matching :1.y tag).
- Note that the guest-auth overlay is test-only and must never reach a
  production config; drop a duplicated comment.

Subject: [PATCH 3/8] refactor(e2e): scope PR to the legacy Tier B harness,
 drop app-next

The chosen direction is the legacy cluster-free harness (packages/app), which
runs the existing specs unmodified. The app-next harness can't load dynamic
plugins yet (blocked upstream), so it's removed from this PR and tracked as a
follow-up; a short note in the doc records why legacy is the target.

- Remove playwright.app-next-local.config.ts and its guest-identity.spec.ts.
- Remove the e2e:app-next-local script.
- Make the overlay and docs legacy-only (keep a "why not app-next yet" note).

Subject: [PATCH 4/8] refactor(e2e): address review on the legacy harness

- Scope the default run to the one verified-green test (guest-signin
  home-page) via testMatch + grep, instead of an unvalidated spec whose
  sidebar navigation may not match the harness config.
- Add a globalSetup that fails fast with the populate command when
  dynamic-plugins-root is empty (clear error instead of a locator timeout).
- Build the shared --config args via array join; document workers=1 and that
  the backend command mirrors packages/backend's start script.
- Doc: describe the grep-scoped default run and the fail-fast guard.

Subject: [PATCH 6/8] ci(e2e): run cluster-free harness on GitHub Actions

Add .github/workflows/e2e-cluster-free.yaml: a no-cluster job that installs
deps + skopeo, populates dynamic-plugins-root from the public catalog index
via the install-dynamic-plugins CLI (same mechanism as the nightly sanity
check), boots the backend + legacy app dev servers in-process, and runs
yarn e2e:legacy-local. Triggers on e2e-tests/** and app-config*.yaml.

Follows the project workflow-security rules: pull_request (no secrets, public
image), pinned action SHAs, minimal permissions, concurrency control.

The 'Install Playwright browser' step hung on 'playwright install --with-deps'
(its apt phase); drop --with-deps since ubuntu-latest already has the libs
headless chromium needs. Add setup-node yarn caching for both lockfiles to cut
the slow root install on subsequent runs.

Subject: [PATCH 8/8] ci(e2e): run cluster-free job in the Playwright container

Use mcr.microsoft.com/playwright:v1.59.1-noble (browsers + OS deps
preinstalled, matching @playwright/test 1.59.1) to eliminate the
playwright-install step that hung on plain ubuntu runners. Enable corepack
for the vendored yarn 4 and cache the yarn global cache explicitly (the
container lacks the yarn binary setup-node's cache relies on).
