+# E2E Smoke Tests
+
+Playwright-based smoke tests that validate the Polaris plugin against a live Headlamp deployment.
+
+## CI
+
+E2E tests run automatically in Gitea Actions on pushes to `main` and pull requests. The workflow (`.gitea/workflows/e2e.yaml`) uses Authentik OIDC for authentication via repo secrets.
+
+### Required Gitea secrets
+
+| Secret               | Description                                                    |
+| -------------------- | -------------------------------------------------------------- |
+| `AUTHENTIK_USERNAME` | Authentik email or username for a CI user with Headlamp access |
+| `AUTHENTIK_PASSWORD` | Password for that user                                         |
+
+## Running Locally
+
+### Option 1: OIDC via Authentik (same as CI)
+
+```bash
+AUTHENTIK_USERNAME=you@example.com AUTHENTIK_PASSWORD=... npm run e2e
+```
+
+The default base URL is `https://headlamp.animaniacs.farh.net`. Override with `HEADLAMP_URL` if needed.
+
+### Option 2: K8s bearer token (port-forward)
+
+```bash
+kubectl port-forward -n kube-system svc/headlamp 4466:80
+export HEADLAMP_TOKEN=$(kubectl create token headlamp -n kube-system)
+HEADLAMP_URL=http://localhost:4466 npm run e2e
+```
+
+Or in headed mode (opens a browser window):
+
+```bash
+HEADLAMP_URL=http://localhost:4466 npm run e2e:headed
+```
+
+## Environment Variables
+
+| Variable             | Required | Default                                | Description                             |
+| -------------------- | -------- | -------------------------------------- | --------------------------------------- |
+| `HEADLAMP_URL`       | No       | `https://headlamp.animaniacs.farh.net` | Base URL of the Headlamp instance       |
+| `AUTHENTIK_USERNAME` | OIDC     | —                                      | Authentik email/username                |
+| `AUTHENTIK_PASSWORD` | OIDC     | —                                      | Authentik password                      |
+| `HEADLAMP_TOKEN`     | Token    | —                                      | Kubernetes bearer token (fallback auth) |
+
+Set either `AUTHENTIK_USERNAME` + `AUTHENTIK_PASSWORD` or `HEADLAMP_TOKEN`. OIDC takes priority if both are set.
+
+## What the Tests Validate
+
+- **Sidebar entry** — The Polaris sidebar item appears after login
+- **Overview page** — Cluster score and check distribution render correctly
+- **Namespaces page** — Table of namespaces loads with clickable links
+- **Namespace detail** — Clicking a namespace shows its score and resource table
+
+These are smoke tests against real cluster data. They verify the plugin loads and renders without errors, not specific data values.
