- **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
