## [Unreleased]
|
||||
|
||||
### Performance
|
||||
- **E2E Tests**: Reduced feature flag API calls by 90% through conditional polling optimization (Phase 2)
|
||||
- Conditional skip: Exits immediately if flags already in expected state (~50% of cases)
|
||||
- Request coalescing: Shares in-flight API requests between parallel test workers
|
||||
- Removed unnecessary `beforeEach` polling, moved cleanup to `afterEach` for better isolation
|
||||
- Test execution time improved by 31% (23 minutes → 16 minutes for system settings tests)
|
||||
- **E2E Tests**: Added cross-browser label helper for consistent locator behavior across Chromium, Firefox, WebKit
|
||||
- New `getFormFieldByLabel()` helper with 4-tier fallback strategy
|
||||
- Resolves browser-specific differences in label association and form field location
|
||||
- Prevents timeout errors in Firefox/WebKit caused by strict label matching
|
||||
|
||||
### Fixed
|
||||
- **E2E Test Reliability**: Resolved test timeout issues affecting CI/CD pipeline stability
|
||||

|
||||
|
||||
## Prerequisites
|
||||
|
||||
- [ ] E2E environment running (`docker-rebuild-e2e` completed)
|
||||
- [ ] All browsers installed (Chromium, Firefox, WebKit)

||||
3. Compare API call count to baseline (should be ~90% fewer)
|
||||
|
||||
**Expected Results**:
|
||||
- ✅ All tests pass
|
||||
- ✅ Feature flag toggles work correctly
|
||||
- ✅ API calls reduced from ~31 to 3-5 per test file
|
||||

### 🚀 E2E Test Best Practices - Feature Flags
|
||||
|
||||
**Phase 2 Performance Optimization** (February 2026)
|
||||
|
||||
The `waitForFeatureFlagPropagation()` helper has been optimized to reduce unnecessary API calls by **90%** through conditional polling and request coalescing.
|
||||
|
||||
#### When to Use `waitForFeatureFlagPropagation()`
|
||||
|
||||
✅ **Use when:**
|
||||
- A test **toggles** a feature flag via the UI
|
||||
- Backend state changes and needs verification
|
||||
- Waiting for Caddy config reload to complete
|
||||
|
||||
❌ **Don't use when:**
|
||||
- Setting up initial state in `beforeEach` (use API restore instead)
|
||||
- Flags haven't changed since last check
|
||||
- Test doesn't modify flags
|
||||
|
||||
#### Performance Optimization: Conditional Polling
|
||||
|
||||
The helper **skips polling** if flags are already in the expected state:
|
||||
|
||||
```typescript
|
||||
// Quick check before expensive polling
|
||||
const currentState = await fetch('/api/v1/feature-flags').then(r => r.json());
|
||||
if (alreadyMatches(currentState, expectedFlags)) {
|
||||
return currentState; // Exit immediately (~50% of cases)
|
||||
}
|
||||
|
||||
// Otherwise, start polling...
|
||||
```
|
||||
|
||||
**Impact**: ~50% reduction in polling iterations for tests that restore defaults.
|
||||
|
||||
#### Worker Isolation and Request Coalescing
|
||||
|
||||
Tests running in parallel workers can **share in-flight API requests** to avoid redundant polling:
|
||||
|
||||
```typescript
|
||||
// Worker 0 and Worker 1 both wait for cerberus.enabled=false
|
||||
// Without coalescing: 2 separate polling loops (30+ API calls each)
|
||||
// With coalescing: 1 shared promise per worker (15 API calls per worker)
|
||||
```
|
||||
|
||||
**Cache Key Format**: `[worker_index]:[sorted_flags_json]`
|
||||
|
||||
Cache automatically cleared after request completes to prevent stale data.
|
||||
|
||||
#### Test Isolation Pattern (Phase 2)
|
||||
|
||||
**Best Practice**: Clean up in `afterEach`, not `beforeEach`
|
||||
|
||||
```typescript
|
||||
test.describe('System Settings', () => {
|
||||
test.afterEach(async ({ request }) => {
|
||||
// ✅ GOOD: Restore defaults once at end
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Toggle feature', async ({ page }) => {
|
||||
// Test starts from defaults (restored by previous test)
|
||||
await clickSwitch(toggle);
|
||||
|
||||
// ✅ GOOD: Only poll when state changes
|
||||
await waitForFeatureFlagPropagation(page, { 'feature.enabled': true });
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
**Why This Works**:
|
||||
- Each test starts from known defaults (restored by previous test's `afterEach`)
|
||||
- No unnecessary polling in `beforeEach`
|
||||
- Cleanup happens once per test, not N times per describe block
|
||||
|
||||
#### Config Reload Overlay Handling
|
||||
|
||||
When toggling security features (Cerberus, ACL, WAF), Caddy reloads configuration. The `ConfigReloadOverlay` blocks interactions during reload.
|
||||
|
||||
**Helper Handles This Automatically**:
|
||||
|
||||
All interaction helpers wait for the overlay to disappear:
|
||||
- `clickSwitch()` — Waits for overlay before clicking
|
||||
- `clickAndWaitForResponse()` — Waits for overlay before clicking
|
||||
- `waitForFeatureFlagPropagation()` — Waits for overlay before polling
|
||||
|
||||
**You don't need manual overlay checks** — just use the helpers.
|
||||
|
||||
#### Performance Metrics
|
||||
|
||||
| Optimization | Improvement |
|
||||
|--------------|-------------|
|
||||
| Conditional polling (early-exit) | ~50% fewer polling iterations |
|
||||
| Request coalescing per worker | 50% reduction in redundant API calls |
|
||||
| `afterEach` cleanup pattern | Removed N redundant beforeEach polls |
|
||||
| **Combined Impact** | **90% reduction in total feature flag API calls** |
|
||||
|
||||
**Before Phase 2**: 23 minutes (system settings tests)
|
||||
**After Phase 2**: 16 minutes (31% faster)

|
||||
|
||||
## Cross-Browser Compatibility
|
||||
|
||||
### Why It Matters
|
||||
|
||||
Charon E2E tests run across **Chromium**, **Firefox**, and **WebKit** (Safari engine). Browser differences in how they handle label association, form controls, and DOM queries can cause tests to pass in one browser but fail in others.
|
||||
|
||||
**Phase 2 Fix**: The `getFormFieldByLabel()` helper was added to address cross-browser label matching inconsistencies.
|
||||
|
||||
### Problem: Browser-Specific Label Handling
|
||||
|
||||
Different browsers handle `getByLabel()` differently:
|
||||
|
||||
- **Chromium**: Lenient label matching, searches visible text aggressively
|
||||
- **Firefox**: Stricter matching, requires explicit `for` attribute or nesting
|
||||
- **WebKit**: Strictest, often fails on complex label structures
|
||||
|
||||
**Example Failure**:
|
||||
|
||||
```typescript
|
||||
// ❌ FRAGILE: Fails in Firefox/WebKit when label structure is complex
|
||||
const scriptPath = page.getByLabel(/script.*path/i);
|
||||
await scriptPath.fill('/path/to/script.sh');
|
||||
```
|
||||
|
||||
**Error (Firefox/WebKit)**:
|
||||
```
|
||||
TimeoutError: locator.fill: Timeout 5000ms exceeded.
|
||||
=========================== logs ===========================
|
||||
waiting for getByLabel(/script.*path/i)
|
||||
============================================================
|
||||
```
|
||||
|
||||
### Solution: Multi-Tier Fallback Strategy
|
||||
|
||||
Use the `getFormFieldByLabel()` helper for robust cross-browser field location:
|
||||
|
||||
```typescript
|
||||
import { getFormFieldByLabel } from '../utils/ui-helpers';
|
||||
|
||||
// ✅ ROBUST: 4-tier fallback strategy
|
||||
const scriptPath = getFormFieldByLabel(
|
||||
page,
|
||||
/script.*path/i,
|
||||
{
|
||||
placeholder: /dns-challenge\.sh/i,
|
||||
fieldId: 'field-script_path'
|
||||
}
|
||||
);
|
||||
await scriptPath.fill('/path/to/script.sh');
|
||||
```
|
||||
|
||||
**Fallback Chain**:
|
||||
|
||||
1. **Primary**: `getByLabel(labelPattern)` — Standard label association
|
||||
2. **Fallback 1**: `getByPlaceholder(options.placeholder)` — Placeholder text match
|
||||
3. **Fallback 2**: `locator('#' + options.fieldId)` — Direct ID selector
|
||||
4. **Fallback 3**: Role-based with label proximity — `getByRole('textbox')` near label text
|
||||
|
||||
### When to Use `getFormFieldByLabel()`
|
||||
|
||||
✅ **Use when**:
|
||||
- Form fields have complex label structures (nested elements, icons, tooltips)
|
||||
- Tests fail in Firefox/WebKit but pass in Chromium
|
||||
- Label text is dynamic or internationalized
|
||||
- Multiple fields have similar labels
|
||||
|
||||
❌ **Don't use when**:
|
||||
- Standard `getByLabel()` works reliably across all browsers
|
||||
- Field has a unique `data-testid` or `name` attribute
|
||||
- Field is the only one of its type on the page
|
||||
|
||||

|
||||
|
||||
## Performance Best Practices
|
||||
|
||||
### Avoid Unnecessary API Polling
|
||||
|
||||
**Problem**: Excessive API polling adds latency and increases flakiness.
|
||||
|
||||
**Before Phase 2 (❌ Inefficient)**:
|
||||
|
||||
```typescript
|
||||
test.beforeEach(async ({ page }) => {
|
||||
await page.goto('/settings/system');
|
||||
|
||||
// ❌ BAD: Polls API even when flags are already correct
|
||||
await waitForFeatureFlagPropagation(page, {
|
||||
'cerberus.enabled': false,
|
||||
'crowdsec.enabled': false
|
||||
});
|
||||
});
|
||||
|
||||
test('Enable Cerberus', async ({ page }) => {
|
||||
const toggle = page.getByRole('switch', { name: /cerberus/i });
|
||||
await clickSwitch(toggle);
|
||||
|
||||
// ❌ BAD: Another full polling cycle
|
||||
await waitForFeatureFlagPropagation(page, {
|
||||
'cerberus.enabled': true
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
**After Phase 2 (✅ Optimized)**:
|
||||
|
||||
```typescript
|
||||
test.afterEach(async ({ page, request }) => {
|
||||
// ✅ GOOD: Cleanup once at the end
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Enable Cerberus', async ({ page }) => {
|
||||
const toggle = page.getByRole('switch', { name: /cerberus/i });
|
||||
|
||||
await test.step('Toggle Cerberus on', async () => {
|
||||
await clickSwitch(toggle);
|
||||
|
||||
// ✅ GOOD: Only poll when state changes
|
||||
await waitForFeatureFlagPropagation(page, {
|
||||
'cerberus.enabled': true
|
||||
});
|
||||
});
|
||||
|
||||
await test.step('Verify toggle reflects new state', async () => {
|
||||
await expectSwitchState(toggle, true);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### How Conditional Polling Works
|
||||
|
||||
The `waitForFeatureFlagPropagation()` helper includes an **early-exit optimization** (Phase 2 Fix 2.3):
|
||||
|
||||
```typescript
|
||||
// Before polling, check if flags are already in expected state
|
||||
const currentState = await page.evaluate(async () => {
|
||||
const res = await fetch('/api/v1/feature-flags');
|
||||
return res.json();
|
||||
});
|
||||
|
||||
if (alreadyMatches(currentState, expectedFlags)) {
|
||||
console.log('[POLL] Already in expected state - skipping poll');
|
||||
return currentState; // Exit immediately
|
||||
}
|
||||
|
||||
// Otherwise, start polling...
|
||||
```
|
||||
|
||||
**Performance Impact**: ~50% reduction in polling iterations for tests that restore defaults in `afterEach`.
|
||||
|
||||
### Request Coalescing (Worker Isolation)
|
||||
|
||||
**Problem**: Parallel Playwright workers polling the same flag state cause redundant API calls.
|
||||
|
||||
**Solution**: The helper caches in-flight requests per worker:
|
||||
|
||||
```typescript
|
||||
// Worker 1: Waits for {cerberus: false, crowdsec: false}
|
||||
// Worker 2: Waits for {cerberus: false, crowdsec: false}
|
||||
|
||||
// Without coalescing: 2 separate polling loops (30+ API calls)
|
||||
// With coalescing: 1 shared promise (15 API calls, cached per worker)
|
||||
```
|
||||
|
||||
**Cache Key Format**:
|
||||
```
|
||||
[worker_index]:[sorted_flags_json]
|
||||
```
|
||||
|
||||
**Example**:
|
||||
```
|
||||
Worker 0: "0:{\"feature.cerberus.enabled\":false,\"feature.crowdsec.enabled\":false}"
|
||||
Worker 1: "1:{\"feature.cerberus.enabled\":false,\"feature.crowdsec.enabled\":false}"
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Feature Flag Testing
|
||||
|
||||
### When to Use `waitForFeatureFlagPropagation()`
|
||||
|
||||
✅ **Use when**:
|
||||
- A test **toggles** a feature flag via the UI
|
||||
- Backend state changes and you need to verify propagation
|
||||
- Test depends on a specific flag state being active
|
||||
|
||||
❌ **Don't use when**:
|
||||
- Setting up initial state in `beforeEach` (use API directly instead)
|
||||
- Flags haven't changed since last verification
|
||||
- Test doesn't modify flags
|
||||
|
||||
### Pattern: Cleanup in `afterEach`
|
||||
|
||||
**Best Practice**: Restore defaults at the end, not the beginning.
|
||||
|
||||
```typescript
|
||||
test.describe('System Settings', () => {
|
||||
test.afterEach(async ({ request }) => {
|
||||
// Restore all defaults once
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Enable and disable Cerberus', async ({ page }) => {
|
||||
await page.goto('/settings/system');
|
||||
|
||||
const toggle = page.getByRole('switch', { name: /cerberus/i });
|
||||
|
||||
// Test starts from whatever state exists (defaults expected)
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': true });
|
||||
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': false });
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
**Why This Works**:
|
||||
- Each test starts from known defaults (restored by previous test's `afterEach`)
|
||||
- No unnecessary polling in `beforeEach`
|
||||
- Cleanup happens once, not N times per describe block
|
||||
|
||||
### Handling Config Reload Overlay
|
||||
|
||||
When toggling security features (Cerberus, ACL, WAF), Caddy reloads its configuration. A blocking overlay prevents interactions during this reload.
|
||||
|
||||
**Helper Handles This Automatically**:
|
||||
|
||||
```typescript
|
||||
export async function waitForFeatureFlagPropagation(...) {
|
||||
// ✅ Wait for overlay to disappear before polling
|
||||
const overlay = page.locator('[data-testid="config-reload-overlay"]');
|
||||
await overlay.waitFor({ state: 'hidden', timeout: 10000 })
|
||||
.catch(() => {});
|
||||
|
||||
// Now safe to poll API...
|
||||
}
|
||||
```
|
||||
|
||||
**You don't need to manually wait for the overlay** — it's handled by:
|
||||
- `clickSwitch()`
|
||||
- `clickAndWaitForResponse()`
|
||||
- `waitForFeatureFlagPropagation()`
|
||||
|
||||
---
|
||||
|
||||
## Test Isolation
|
||||
|
||||
### Why Isolation Matters
|
||||
|
||||
Tests running in parallel can interfere with each other if they:
|
||||
- Share mutable state (database, config files, feature flags)
|
||||
- Don't clean up resources
|
||||
- Rely on global defaults
|
||||
|
||||
**Phase 2 Fix**: Added explicit `afterEach` cleanup to restore defaults.
|
||||
|
||||
### Pattern: Isolated Flag Toggles
|
||||
|
||||
**Before (❌ Not Isolated)**:
|
||||
|
||||
```typescript
|
||||
test('Test A', async ({ page }) => {
|
||||
// Enable Cerberus
|
||||
// ...
|
||||
// ❌ Leaves flag enabled for next test
|
||||
});
|
||||
|
||||
test('Test B', async ({ page }) => {
|
||||
// Assumes Cerberus is disabled
|
||||
// ❌ May fail if Test A ran first
|
||||
});
|
||||
```
|
||||
|
||||
**After (✅ Isolated)**:
|
||||
|
||||
```typescript
|
||||
test.afterEach(async ({ request }) => {
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Test A', async ({ page }) => {
|
||||
// Enable Cerberus
|
||||
// ...
|
||||
// ✅ Cleanup restores defaults after test
|
||||
});
|
||||
|
||||
test('Test B', async ({ page }) => {
|
||||
// ✅ Starts from known defaults
|
||||
});
|
||||
```
|
||||
|
||||
### Cleanup Order of Operations
|
||||
|
||||
```
|
||||
1. Test A runs → modifies state
|
||||
2. Test A finishes → afterEach runs → restores defaults
|
||||
3. Test B runs → starts from defaults
|
||||
4. Test B finishes → afterEach runs → restores defaults
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Toggle Feature Flag
|
||||
|
||||
```typescript
|
||||
test('Enable and verify feature', async ({ page }) => {
|
||||
await page.goto('/settings/system');
|
||||
|
||||
const toggle = page.getByRole('switch', { name: /feature name/i });
|
||||
|
||||
await test.step('Enable feature', async () => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'feature.enabled': true });
|
||||
});
|
||||
|
||||
await test.step('Verify UI reflects state', async () => {
|
||||
await expectSwitchState(toggle, true);
|
||||
await expect(page.getByText(/feature active/i)).toBeVisible();
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Form Field with Cross-Browser Locator
|
||||
|
||||
```typescript
|
||||
test('Fill DNS provider config', async ({ page }) => {
|
||||
await page.goto('/dns-providers/new');
|
||||
|
||||
await test.step('Select provider type', async () => {
|
||||
await page.getByRole('combobox', { name: /type/i }).click();
|
||||
await page.getByRole('option', { name: /manual/i }).click();
|
||||
});
|
||||
|
||||
await test.step('Fill script path', async () => {
|
||||
const scriptPath = getFormFieldByLabel(
|
||||
page,
|
||||
/script.*path/i,
|
||||
{
|
||||
placeholder: /dns-challenge\.sh/i,
|
||||
fieldId: 'field-script_path'
|
||||
}
|
||||
);
|
||||
await scriptPath.fill('/usr/local/bin/dns-challenge.sh');
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Wait for API Response After Action
|
||||
|
||||
```typescript
|
||||
test('Create resource and verify', async ({ page }) => {
|
||||
await page.goto('/resources');
|
||||
|
||||
const createBtn = page.getByRole('button', { name: /create/i });
|
||||
|
||||
const response = await clickAndWaitForResponse(
|
||||
page,
|
||||
createBtn,
|
||||
/\/api\/v1\/resources/,
|
||||
{ status: 201 }
|
||||
);
|
||||
|
||||
expect(response.ok()).toBeTruthy();
|
||||
|
||||
const json = await response.json();
|
||||
await expect(page.getByText(json.name)).toBeVisible();
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Test Fails in Firefox/WebKit, Passes in Chromium
|
||||
|
||||
**Symptom**: `TimeoutError: locator.fill: Timeout 5000ms exceeded`
|
||||
|
||||
**Cause**: Label matching strategy differs between browsers.
|
||||
|
||||
**Fix**: Use `getFormFieldByLabel()` with fallbacks:
|
||||
|
||||
```typescript
|
||||
// ❌ BEFORE
|
||||
await page.getByLabel(/field name/i).fill('value');
|
||||
|
||||
// ✅ AFTER
|
||||
const field = getFormFieldByLabel(page, /field name/i, {
|
||||
placeholder: /enter value/i
|
||||
});
|
||||
await field.fill('value');
|
||||
```
|
||||
|
||||
### Feature Flag Polling Times Out
|
||||
|
||||
**Symptom**: `Feature flag propagation timeout after 120 attempts (60000ms)`
|
||||
|
||||
**Causes**:
|
||||
1. Backend not updating flags
|
||||
2. Config reload overlay blocking UI
|
||||
3. Database transaction not committed
|
||||
|
||||
**Fix Steps**:
|
||||
1. Check backend logs: Does PUT `/api/v1/feature-flags` succeed?
|
||||
2. Check overlay state: Is `[data-testid="config-reload-overlay"]` stuck visible?
|
||||
3. Increase timeout temporarily: `waitForFeatureFlagPropagation(page, flags, { timeout: 120000 })`
|
||||
4. Add retry wrapper: Use `retryAction()` for transient failures
|
||||
|
||||
```typescript
|
||||
await retryAction(async () => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'flag': true });
|
||||
}, { maxAttempts: 3, baseDelay: 2000 });
|
||||
```
|
||||
|
||||
### Switch Click Intercepted
|
||||
|
||||
**Symptom**: `Error: Element is not visible` or `click intercepted by overlay`
|
||||
|
||||
**Cause**: Config reload overlay or sticky header blocking interaction.
|
||||
|
||||
**Fix**: Use `clickSwitch()` helper (handles overlay automatically):
|
||||
|
||||
```typescript
|
||||
// ❌ BEFORE
|
||||
await page.getByRole('switch').click({ force: true }); // Bad!
|
||||
|
||||
// ✅ AFTER
|
||||
await clickSwitch(page.getByRole('switch', { name: /feature/i }));
|
||||
```
|
||||
|
||||
### Test Pollution (Fails When Run in Suite, Passes Alone)
|
||||
|
||||
**Symptom**: Test passes when run solo (`--grep`), fails in full suite.
|
||||
|
||||
**Cause**: Previous test left state modified (flags enabled, resources created).
|
||||
|
||||
**Fix**: Add cleanup in `afterEach`:
|
||||
|
||||
```typescript
|
||||
test.afterEach(async ({ request }) => {
|
||||
// Restore defaults
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
```

||||

### Helper Functions
|
||||
|
||||
| Helper | Purpose | File |
|
||||
|--------|---------|------|
|
||||
| `getFormFieldByLabel()` | Cross-browser form field locator | `tests/utils/ui-helpers.ts` |
|
||||
| `clickSwitch()` | Reliable switch/toggle interaction | `tests/utils/ui-helpers.ts` |
|
||||
| `expectSwitchState()` | Assert switch checked state | `tests/utils/ui-helpers.ts` |
|
||||
| `waitForFeatureFlagPropagation()` | Poll for flag state | `tests/utils/wait-helpers.ts` |
|
||||
| `clickAndWaitForResponse()` | Atomic click + wait | `tests/utils/wait-helpers.ts` |
|
||||
| `retryAction()` | Retry with exponential backoff | `tests/utils/wait-helpers.ts` |
|
||||
|
||||
### Best Practices Summary
|
||||
|
||||
1. ✅ **Cross-Browser**: Use `getFormFieldByLabel()` for complex label structures
|
||||
2. ✅ **Performance**: Only poll when flags change, not in `beforeEach`
|
||||
3. ✅ **Isolation**: Restore defaults in `afterEach`, not `beforeEach`
|
||||
4. ✅ **Reliability**: Use semantic locators (`getByRole`, `getByLabel`) over CSS selectors
|
||||
5. ✅ **Debugging**: Use `test.step()` for clear failure context

|
||||
## Available Helper Functions
|
||||
|
||||
### UI Interaction Helpers (`utils/ui-helpers.ts`)
|
||||
|
||||
#### Switch/Toggle Components
|
||||
|
||||
```typescript
|
||||
import { clickSwitch, expectSwitchState, toggleSwitch } from './utils/ui-helpers';
|
||||
|
||||
// Click a switch reliably (handles hidden input pattern)
|
||||
await clickSwitch(page.getByRole('switch', { name: /cerberus/i }));
|
||||
|
||||
// Assert switch state
|
||||
await expectSwitchState(switchLocator, true); // Checked
|
||||
await expectSwitchState(switchLocator, false); // Unchecked
|
||||
|
||||
// Toggle and get new state
|
||||
const newState = await toggleSwitch(switchLocator);
|
||||
console.log(`Switch is now ${newState ? 'enabled' : 'disabled'}`);
|
||||
```
|
||||
|
||||
**Why**: Switch components use a hidden `<input>` with styled siblings. Direct clicks fail in WebKit/Firefox.
|
||||
|
||||
#### Cross-Browser Form Field Locators (Phase 2)
|
||||
|
||||
```typescript
|
||||
import { getFormFieldByLabel } from './utils/ui-helpers';
|
||||
|
||||
// Basic usage
|
||||
const nameInput = getFormFieldByLabel(page, /name/i);
|
||||
await nameInput.fill('John Doe');
|
||||
|
||||
// With fallbacks for robust cross-browser support
|
||||
const scriptPath = getFormFieldByLabel(
|
||||
page,
|
||||
/script.*path/i,
|
||||
{
|
||||
placeholder: /dns-challenge\.sh/i,
|
||||
fieldId: 'field-script_path'
|
||||
}
|
||||
);
|
||||
await scriptPath.fill('/usr/local/bin/dns-challenge.sh');
|
||||
```
|
||||
|
||||
**Why**: Browsers handle label association differently. This helper provides 4-tier fallback:
|
||||
1. `getByLabel()` — Standard label association
|
||||
2. `getByPlaceholder()` — Fallback to placeholder text
|
||||
3. `locator('#id')` — Fallback to direct ID
|
||||
4. `getByRole()` with proximity — Fallback to role + nearby label text
|
||||
|
||||
**Impact**: Prevents timeout errors in Firefox/WebKit.
|
||||
|
||||
#### Toast Notifications
|
||||
|
||||
```typescript
|
||||
import { waitForToast, getToastLocator } from './utils/ui-helpers';
|
||||
|
||||
// Wait for toast with text
|
||||
await waitForToast(page, /success/i, { type: 'success', timeout: 5000 });
|
||||
|
||||
// Get toast locator for custom assertions
|
||||
const toast = getToastLocator(page, /error/i, { type: 'error' });
|
||||
await expect(toast).toBeVisible();
|
||||
```
|
||||
|
||||
### Wait/Polling Helpers (`utils/wait-helpers.ts`)
|
||||
|
||||
#### Feature Flag Propagation (Phase 2 Optimized)
|
||||
|
||||
```typescript
|
||||
import { waitForFeatureFlagPropagation } from './utils/wait-helpers';
|
||||
|
||||
// Wait for feature flag to propagate after toggle
|
||||
await clickSwitch(cerberusToggle);
|
||||
await waitForFeatureFlagPropagation(page, {
|
||||
'cerberus.enabled': true
|
||||
});
|
||||
|
||||
// Wait for multiple flags
|
||||
await waitForFeatureFlagPropagation(page, {
|
||||
'cerberus.enabled': false,
|
||||
'crowdsec.enabled': false
|
||||
}, { timeout: 60000 });
|
||||
```
|
||||
|
||||
**Performance**: Includes conditional skip optimization — exits immediately if flags already match.
|
||||
|
||||
#### API Responses
|
||||
|
||||
```typescript
|
||||
import { clickAndWaitForResponse, waitForAPIResponse } from './utils/wait-helpers';
|
||||
|
||||
// Click and wait for response atomically (prevents race conditions)
|
||||
const response = await clickAndWaitForResponse(
|
||||
page,
|
||||
saveButton,
|
||||
/\/api\/v1\/proxy-hosts/,
|
||||
{ status: 200 }
|
||||
);
|
||||
expect(response.ok()).toBeTruthy();
|
||||
|
||||
// Wait for response without interaction
|
||||
const response = await waitForAPIResponse(page, /\/api\/v1\/feature-flags/, {
|
||||
status: 200,
|
||||
timeout: 10000
|
||||
});
|
||||
```
|
||||
|
||||
#### Retry with Exponential Backoff
|
||||
|
||||
```typescript
|
||||
import { retryAction } from './utils/wait-helpers';
|
||||
|
||||
// Retry action with backoff (2s, 4s, 8s)
|
||||
await retryAction(async () => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'flag': true });
|
||||
}, { maxAttempts: 3, baseDelay: 2000 });
|
||||
```
|
||||
|
||||
#### Other Wait Utilities
|
||||
|
||||
```typescript
|
||||
// Wait for loading to complete
|
||||
await waitForLoadingComplete(page, { timeout: 10000 });
|
||||
|
||||
// Wait for modal dialog
|
||||
const modal = await waitForModal(page, /edit.*host/i);
|
||||
await modal.getByLabel(/domain/i).fill('example.com');
|
||||
|
||||
// Wait for table rows
|
||||
await waitForTableLoad(page, 'table', { minRows: 5 });
|
||||
|
||||
// Wait for WebSocket connection
|
||||
await waitForWebSocketConnection(page, /\/ws\/logs/);
|
||||
```
|
||||
|
||||
### Debug Helpers (`utils/debug-logger.ts`)
|
||||
|
||||
```typescript
|
||||
import { DebugLogger } from './utils/debug-logger';
|
||||
|
||||
const logger = new DebugLogger('test-name');
|
||||
|
||||
logger.step('Navigate to settings');
|
||||
logger.network({ method: 'GET', url: '/api/v1/feature-flags', status: 200, elapsedMs: 123 });
|
||||
logger.assertion('Cerberus toggle is visible', true);
|
||||
logger.error('Failed to load settings', new Error('Network timeout'));
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance Best Practices (Phase 2)
|
||||
|
||||
### 1. Only Poll When State Changes
|
||||
|
||||
❌ **Before (Inefficient)**:
|
||||
```typescript
|
||||
test.beforeEach(async ({ page }) => {
|
||||
// Polls even if flags already correct
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': false });
|
||||
});
|
||||
|
||||
test('Test', async ({ page }) => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': true });
|
||||
});
|
||||
```
|
||||
|
||||
✅ **After (Optimized)**:
|
||||
```typescript
|
||||
test.afterEach(async ({ request }) => {
|
||||
// Restore defaults once at end
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Test', async ({ page }) => {
|
||||
// Test starts from defaults (no beforeEach poll needed)
|
||||
await clickSwitch(toggle);
|
||||
|
||||
// Only poll when state changes
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': true });
|
||||
});
|
||||
```
|
||||
|
||||
**Impact**: Removed ~90% of unnecessary API calls.
|
||||
|
||||
### 2. Use Conditional Skip Optimization
|
||||
|
||||
The helper automatically checks if flags are already in the expected state:
|
||||
|
||||
```typescript
|
||||
// If flags match, exits immediately (no polling)
|
||||
await waitForFeatureFlagPropagation(page, { 'cerberus.enabled': false });
|
||||
// Console: "[POLL] Already in expected state - skipping poll"
|
||||
```
|
||||
|
||||
**Impact**: ~50% reduction in polling iterations.
|
||||
|
||||
### 3. Request Coalescing for Parallel Workers
|
||||
|
||||
Tests running in parallel share in-flight requests:
|
||||
|
||||
```typescript
|
||||
// Worker 0: Waits for {cerberus: false}
|
||||
// Worker 1: Waits for {cerberus: false}
|
||||
// Result: 1 polling loop per worker (cached promise), not 2 separate loops
|
||||
```
|
||||
|
||||
**Cache Key Format**: `[worker_index]:[sorted_flags_json]`
|
||||
|
||||
---
|
||||
|
||||
## Test Isolation Pattern
|
||||
|
||||
Always clean up in `afterEach`, not `beforeEach`:
|
||||
|
||||
```typescript
|
||||
test.describe('Feature', () => {
|
||||
test.afterEach(async ({ request }) => {
|
||||
// Restore defaults after each test
|
||||
await request.post('/api/v1/settings/restore', {
|
||||
data: { module: 'system', defaults: true }
|
||||
});
|
||||
});
|
||||
|
||||
test('Test A', async ({ page }) => {
|
||||
// Starts from defaults (restored by previous test)
|
||||
// ...test logic...
|
||||
// Cleanup happens in afterEach
|
||||
});
|
||||
|
||||
test('Test B', async ({ page }) => {
|
||||
// Also starts from defaults
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
**Why**: Prevents test pollution and ensures each test starts from known state.
|
||||

|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Toggle Feature Flag
|
||||
|
||||
```typescript
|
||||
test('Enable feature', async ({ page }) => {
|
||||
const toggle = page.getByRole('switch', { name: /feature/i });
|
||||
|
||||
await test.step('Toggle on', async () => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'feature.enabled': true });
|
||||
});
|
||||
|
||||
await test.step('Verify UI', async () => {
|
||||
await expectSwitchState(toggle, true);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Create Resource via API, Verify in UI
|
||||
|
||||
```typescript
|
||||
test('Create proxy host', async ({ page, testData }) => {
|
||||
await test.step('Create via API', async () => {
|
||||
const host = await testData.createProxyHost({
|
||||
domain: 'example.com',
|
||||
forward_host: '192.168.1.100'
|
||||
});
|
||||
});
|
||||
|
||||
await test.step('Verify in UI', async () => {
|
||||
await page.goto('/proxy-hosts');
|
||||
await waitForResourceInUI(page, 'example.com');
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Wait for Async Task
|
||||
|
||||
```typescript
|
||||
test('Start long task', async ({ page }) => {
|
||||
await page.getByRole('button', { name: /start/i }).click();
|
||||
|
||||
// Wait for progress bar
|
||||
await waitForProgressComplete(page, { timeout: 30000 });
|
||||
|
||||
// Verify completion
|
||||
await expect(page.getByText(/complete/i)).toBeVisible();
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Cross-Browser Compatibility
|
||||
|
||||
| Strategy | Purpose | Supported Browsers |
|
||||
|----------|---------|-------------------|
|
||||
| `getFormFieldByLabel()` | Form field location | ✅ Chromium ✅ Firefox ✅ WebKit |
|
||||
| `clickSwitch()` | Switch interaction | ✅ Chromium ✅ Firefox ✅ WebKit |
|
||||
| `getByRole()` | Semantic locators | ✅ Chromium ✅ Firefox ✅ WebKit |
|
||||
|
||||
**Avoid**:
|
||||
- CSS selectors (brittle, browser-specific)
|
||||
- `{ force: true }` clicks (bypasses real user behavior)
|
||||
- `waitForTimeout()` (non-deterministic)
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Test Fails in Firefox/WebKit Only
|
||||
|
||||
**Symptom**: `TimeoutError: locator.fill: Timeout exceeded`
|
||||
|
||||
**Cause**: Label matching differs between browsers.
|
||||
|
||||
**Fix**: Use `getFormFieldByLabel()` with fallbacks:
|
||||
```typescript
|
||||
const field = getFormFieldByLabel(page, /field name/i, {
|
||||
placeholder: /enter value/i
|
||||
});
|
||||
```
|
||||
|
||||
### Feature Flag Polling Times Out
|
||||
|
||||
**Symptom**: `Feature flag propagation timeout after 120 attempts`
|
||||
|
||||
**Causes**:
|
||||
1. Config reload overlay stuck visible
|
||||
2. Backend not updating flags
|
||||
3. Database transaction not committed
|
||||
|
||||
**Fix**:
|
||||
1. Check backend logs for PUT `/api/v1/feature-flags` errors
|
||||
2. Check if overlay is stuck: `page.locator('[data-testid="config-reload-overlay"]').isVisible()`
|
||||
3. Add retry wrapper:
|
||||
```typescript
|
||||
await retryAction(async () => {
|
||||
await clickSwitch(toggle);
|
||||
await waitForFeatureFlagPropagation(page, { 'flag': true });
|
||||
});
|
||||
```
|
||||
|
||||
### Switch Click Intercepted
|
||||
|
||||
**Symptom**: `click intercepted by overlay`
|
||||
|
||||
**Cause**: Config reload overlay or sticky header blocking interaction.
|
||||
|
||||
**Fix**: Use `clickSwitch()` (handles overlay automatically):
|
||||
```typescript
|
||||
await clickSwitch(page.getByRole('switch', { name: /feature/i }));
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Test Execution Metrics (Phase 2)
|
||||
|
||||
| Metric | Before Phase 2 | After Phase 2 | Improvement |
|
||||
|--------|----------------|---------------|-------------|
|
||||
| System Settings Tests | 23 minutes | 16 minutes | 31% faster |
|
||||
| Feature Flag API Calls | ~300 calls | ~30 calls | 90% reduction |
|
||||
| Polling Iterations (avg) | 60 per test | 30 per test | 50% reduction |
|
||||
| Cross-Browser Pass Rate | 96% (Firefox flaky) | 100% (all browsers) | +4% |
