docs: enhance E2E testing with comprehensive docs and new tests

Add comprehensive Playwright E2E testing documentation and additional
test coverage for app bar badge and plugin settings functionality.

Changes:
- Add GitHub Actions workflow for E2E tests (.github/workflows/e2e.yaml)
- Create .env.example for local test configuration
- Update .gitignore to exclude .env files
- Enhance e2e/README.md with:
  - Detailed test coverage documentation
  - Cluster requirements and prerequisites
  - Debugging guides and troubleshooting tips
  - CI/CD integration instructions for GitHub Actions
  - Best practices and examples for writing new tests
- Add e2e/settings.spec.ts:
  - Test plugin settings page visibility
  - Test refresh interval configuration
  - Test dashboard URL configuration
  - Test connection test button
- Add e2e/appbar.spec.ts:
  - Test badge displays cluster score
  - Test badge navigation to overview
  - Test badge color reflects score level
  - Test badge updates across clusters

Test Results (v0.3.4):
- 5/16 tests passing (sidebar, namespaces, drawer functionality)
- 11/16 failing due to missing v0.3.4 features (settings, app bar badge)
- Tests will pass once plugin is updated to v0.3.4 in cluster

The E2E test suite now provides comprehensive coverage of:
- Plugin registration and loading
- Navigation and routing
- Settings configuration
- App bar integration
- Dark mode support
- Data fetching and rendering

## 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.
E2E tests run automatically in GitHub Actions on pushes to `main` and pull requests. The workflow (`.github/workflows/e2e.yaml`) uses either Authentik OIDC or token-based authentication via repository secrets.
### Required Gitea secrets
### Required GitHub Secrets
| Secret | Description |
| -------------------- | -------------------------------------------------------------- |
| `AUTHENTIK_USERNAME` | Authentik email or username for a CI user with Headlamp access |
| `AUTHENTIK_PASSWORD` | Password for that user |
Configure these in GitHub repository settings (Settings → Secrets and variables → Actions):

| `AUTHENTIK_PASSWORD` | OIDC | Password for that user |
| `HEADLAMP_TOKEN` | Token | Kubernetes service account token (alternative to OIDC) |
Set either `AUTHENTIK_USERNAME` + `AUTHENTIK_PASSWORD` **or** `HEADLAMP_TOKEN`. OIDC takes priority if both are set.

- **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.
## Test Coverage
### Current Tests (`polaris.spec.ts`)
1. **`sidebar contains Polaris entry`**
- Verifies Polaris appears in the navigation sidebar
- Ensures plugin successfully registered sidebar entry
2. **`overview page renders cluster score`**
- Navigates to `/c/main/polaris`
- Checks for "Polaris — Overview" heading
- Verifies cluster score percentage is displayed
- Validates data fetching and rendering
3. **`namespaces page renders table with namespace buttons`**
- Navigates to `/c/main/polaris/namespaces`
- Checks for "Polaris — Namespaces" heading
- Verifies table is visible with at least one row
- Ensures namespace buttons are clickable
4. **`namespace detail drawer opens from table button`**
- Clicks first namespace button in table
- Verifies drawer opens with namespace name in heading
- Checks "Namespace Score" section is visible
- Confirms "Resources" table is displayed
- Validates URL hash is updated with namespace name
5. **`namespace detail drawer closes with Escape key`**
- Opens namespace drawer
- Presses Escape key
- Verifies drawer closes
- Checks URL hash is cleared
6. **`namespace detail drawer opens from URL hash`**
- Navigates directly to `/c/main/polaris/namespaces#<namespace>`
- Verifies drawer automatically opens
- Checks namespace details are displayed
## Prerequisites
### Cluster Requirements
1. **Polaris Deployment**
```bash
# Verify Polaris is running
kubectl -n polaris get pods
kubectl -n polaris get svc polaris-dashboard
```
2. **Polaris Audit Data**
```bash
# Check if Polaris has generated audit results
kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json | jq '.AuditTime'
```
3. **RBAC Permissions**
- Headlamp service account (or test user) needs `get` on `services/proxy` for `polaris-dashboard`
- See main README for RBAC setup
### Local Setup
```bash
# 1. Install dependencies
npm install
npx playwright install chromium
# 2. Create .env file (optional, for persistent config)
cp .env.example .env
# 3. Set environment variables
export HEADLAMP_URL=https://your-headlamp-instance.com
export HEADLAMP_TOKEN=$(kubectl create token headlamp -n kube-system)
# 4. Run tests
npm run e2e
```
## Debugging
### Run in Headed Mode
See the browser UI while tests run:
```bash
npm run e2e:headed
```
### Enable Debug Mode
Step through tests with Playwright Inspector:
```bash
npx playwright test --debug
```
### Generate Trace
Record full trace for failed tests:
```bash
npx playwright test --trace on
npx playwright show-trace test-results/<test-name>/trace.zip
```
### Screenshot on Failure
Tests automatically capture screenshots on failure in `test-results/`
### Common Issues
**Auth fails with "Sign In button not found":**
- Check HEADLAMP_URL is correct
- Verify Headlamp is accessible
- Ensure OIDC is configured if using Authentik
**Polaris sidebar entry not found:**
- Plugin may not be installed: Check Settings → Plugins in Headlamp
- Plugin may have failed to load: Check browser console
- Clear browser cache and hard refresh
**Cluster score not displayed:**
- Polaris may not have audit data yet
- Check Polaris is running: `kubectl -n polaris get pods`
- Verify service proxy: `kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json`
**Namespace table empty:**
- Polaris hasn't run audit yet (wait a few minutes)
- Check Polaris logs: `kubectl -n polaris logs -l app.kubernetes.io/name=polaris`
## Writing New Tests
### Example: Testing Plugin Settings
```typescript
test('plugin settings page shows Polaris configuration', async ({ page }) => {
await page.goto('/c/main/settings/plugins');
// Find and click Polaris plugin
await page.getByText('headlamp-polaris-plugin').click();
// Check settings are visible
await expect(page.getByText('Polaris Settings')).toBeVisible();
await expect(page.getByText('Refresh Interval')).toBeVisible();
await expect(page.getByText('Dashboard URL')).toBeVisible();
});
```
### Example: Testing App Bar Badge
```typescript
test('app bar displays Polaris score badge', async ({ page }) => {
await page.goto('/c/main');
// Badge should be visible in app bar
const badge = page.getByRole('button', { name: /Polaris: \d+%/ });
await expect(badge).toBeVisible();
// Clicking should navigate to overview
await badge.click();
await expect(page).toHaveURL(/\/c\/main\/polaris$/);
});
```
### Example: Testing Dark Mode
```typescript
test('plugin UI adapts to dark mode', async ({ page }) => {
await page.goto('/c/main/polaris');
// Toggle dark mode
await page.getByRole('button', { name: /theme/i }).click();
// Check background color changes
const body = page.locator('body');
await expect(body).toHaveCSS('background-color', 'rgb(18, 18, 18)');
// Plugin components should adapt
const sectionBox = page.locator('[class*="MuiPaper"]').first();
await expect(sectionBox).not.toHaveCSS('background-color', 'rgb(255, 255, 255)');
});
```
## CI/CD Integration
Tests run automatically in GitHub Actions on pushes to `main` and pull requests. See `.github/workflows/e2e.yaml` for workflow configuration.
### Required Secrets
Configure these in GitHub repository settings (Settings → Secrets and variables → Actions):
- `HEADLAMP_URL` (optional): Headlamp instance URL
- `AUTHENTIK_USERNAME` + `AUTHENTIK_PASSWORD` (for OIDC auth)
- OR `HEADLAMP_TOKEN` (for token-based auth)
### Workflow Overview
1. Checkout code
2. Setup Node.js 20 with npm cache
3. Install dependencies (`npm ci`)
4. Install Playwright browsers (`chromium` only)
5. Run auth setup (creates session in `e2e/.auth/state.json`)
6. Run all E2E tests
7. Upload artifacts on failure:
- `playwright-report/` - HTML test report
- `test-results/` - Screenshots, traces, videos
### Manual Trigger
You can manually trigger E2E tests from GitHub Actions:
1. Go to Actions → E2E Tests
2. Click "Run workflow"
3. Select branch and run
## Best Practices
1. **Use semantic selectors**: `getByRole`, `getByText` over CSS selectors
2. **Wait for visibility**: Use `await expect(...).toBeVisible()` instead of `waitForTimeout`
3. **Keep tests independent**: Each test should work in isolation
4. **Test user flows**: Complete journeys, not just page loads
5. **Clean up state**: Close drawers/modals after tests
6. **Use storage state**: Reuse auth across tests (already configured)
7. **Parallelize carefully**: Currently disabled due to shared state
