# CI Flake Triage Implementation - Frontend_Dev
|
||||
|
||||
**Date**: January 26, 2026
|
||||
**Feature Branch**: feature/beta-release
|
||||
**Focus**: Playwright/tests and global setup (not app UI)
|
||||
|
||||
## Summary
|
||||
|
||||
Implemented deterministic fixes for CI flakes in Playwright E2E tests, focusing on health checks, ACL reset verification, shared helpers, and shard-specific improvements.
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Global Setup - Health Probes & Deterministic ACL Disable
|
||||
|
||||
**File**: `tests/global-setup.ts`
|
||||
|
||||
**Changes**:
|
||||
- Added `checkEmergencyServerHealth()` function to probe `http://localhost:2019/config` with 3s timeout
|
||||
- Added `checkTier2ServerHealth()` function to probe `http://localhost:2020/health` with 3s timeout
|
||||
- Both health checks are non-blocking (skip if unavailable, don't fail setup)
|
||||
- Added URL analysis logging (IPv4 vs IPv6, localhost detection) for debugging cookie domain issues
|
||||
- Implemented `verifySecurityDisabled()` with 2-attempt retry and fail-fast:
|
||||
- Checks `/api/v1/security/config` for ACL and rate-limit state
|
||||
- Retries emergency reset once if still enabled
|
||||
- Fails with actionable error if security remains enabled after retry
|
||||
- Logs include emojis for easy scanning in CI output
|
||||
|
||||
**Rationale**: Emergency and tier-2 servers are optional; tests should skip gracefully if unavailable. ACL/rate-limit must be disabled deterministically or tests fail with clear diagnostics.
|
||||
|
||||
### 2. TestDataManager - ACL Safety Check
|
||||
|
||||
**File**: `tests/utils/TestDataManager.ts`
|
||||
|
||||
**Changes**:
|
||||
- Added `assertSecurityDisabled()` method
|
||||
- Checks `/api/v1/security/config` before operations
|
||||
- Throws actionable error if ACL or rate-limit is enabled
|
||||
- Idempotent: skips check if endpoint unavailable (no-op in environments without endpoint)
|
||||
|
||||
**Usage**:
|
||||
```typescript
|
||||
await testData.assertSecurityDisabled(); // Before creating resources
|
||||
const host = await testData.createProxyHost(config);
|
||||
```
|
||||
|
||||
**Rationale**: Fail-fast with clear error when security is blocking operations, rather than cryptic 403 errors.
|
||||
|
||||
### 3. Shared UI Helpers
|
||||
|
||||
**File**: `tests/utils/ui-helpers.ts` (new)
|
||||
|
||||
**Helpers Created**:
|
||||
|
||||
#### `getToastLocator(page, text?, options)`
|
||||
- Uses `data-testid="toast-{type}"` for role-based selection
|
||||
- Avoids strict-mode violations with `.first()`
|
||||
- Short retry timeout (default 5s)
|
||||
- Filters by text if provided
|
||||
|
||||
#### `waitForToast(page, text, options)`
|
||||
- Wrapper around `getToastLocator` with built-in wait
|
||||
- Replaces `page.locator('[data-testid="toast-success"]').first()` pattern
|
||||
|
||||
#### `getRowScopedButton(page, rowIdentifier, buttonName, options)`
|
||||
- Finds button within specific table row
|
||||
- Avoids strict-mode collisions when multiple rows have same button
|
||||
- Example: Find "Resend" button in row containing "user@example.com"
|
||||
|
||||
#### `getRowScopedIconButton(page, rowIdentifier, iconClass)`
|
||||
- Finds button by icon class (e.g., `lucide-mail`) within row
|
||||
- Fallback for buttons without proper accessible names
|
||||
|
||||
#### `getCertificateValidationMessage(page, messagePattern)`
|
||||
- Targets validation message with proper role (`alert`, `status`) or error class
|
||||
- Avoids brittle `getByText()` that can match unrelated elements
|
||||
|
||||
#### `refreshListAndWait(page, options)`
|
||||
- Reloads page and waits for table to stabilize
|
||||
- Ensures list reflects changes after create/update operations
|
||||
|
||||
**Rationale**: DRY principle, consistent locator strategies, avoid strict-mode violations, improve test reliability.
|
||||
|
||||
### 4. Shard 1 Fixes - DNS Provider CRUD
|
||||
|
||||
**File**: `tests/dns-provider-crud.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Imported `getToastLocator` and `refreshListAndWait` from `ui-helpers`
|
||||
- Updated "Manual DNS provider" test:
|
||||
- Replaced raw toast locator with `getToastLocator(page, /success|created/i, { type: 'success' })`
|
||||
- Added `refreshListAndWait(page)` after create to ensure list updates
|
||||
- Updated "Webhook DNS provider" test:
|
||||
- Replaced raw toast locator with `getToastLocator`
|
||||
- Updated "Update provider name" test:
|
||||
- Replaced raw toast locator with `getToastLocator`
|
||||
|
||||
**Rationale**: Toast helper reduces duplication and ensures consistent detection. Refresh ensures provider appears in list after creation.
|
||||
|
||||
### 5. Shard 2 Fixes - Emergency & Tier-2 Tests
|
||||
|
||||
**File**: `tests/emergency-server/emergency-server.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Added `checkEmergencyServerHealth()` function
|
||||
- Added `test.beforeAll()` hook to check health before suite
|
||||
- Skips entire suite if emergency server unavailable (port 2019)
|
||||
|
||||
**File**: `tests/emergency-server/tier2-validation.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Added `test.beforeAll()` hook to check tier-2 health (port 2020)
|
||||
- Skips entire suite if tier-2 server unavailable
|
||||
- Logs health check result for CI visibility
|
||||
|
||||
**Rationale**: Emergency and tier-2 servers are optional. Tests should skip gracefully rather than hang or timeout.
|
||||
|
||||
### 6. Shard 3 Fixes - Certificate Email Validation
|
||||
|
||||
**File**: `tests/settings/account-settings.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Imported `getCertificateValidationMessage` from `ui-helpers`
|
||||
- Updated "Validate certificate email format" test:
|
||||
- Replaced `page.getByText(/invalid.*email|email.*invalid/i)` with `getCertificateValidationMessage(page, /invalid.*email|email.*invalid/i)`
|
||||
- Targets visible validation message with proper role/text
|
||||
|
||||
**Rationale**: Brittle `getByText` can match unrelated elements. Helper targets proper validation message role.
|
||||
|
||||
### 7. Shard 4 Fixes - System Settings & User Management
|
||||
|
||||
**File**: `tests/settings/system-settings.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Imported `getToastLocator` from `ui-helpers`
|
||||
- Updated 3 toast locators:
|
||||
- "Save general settings" test: success toast
|
||||
- "Show error for unreachable URL" test: error toast
|
||||
- "Update public URL setting" test: success toast
|
||||
- Replaced complex `.or()` chains with single `getToastLocator` call
|
||||
|
||||
**File**: `tests/settings/user-management.spec.ts`
|
||||
|
||||
**Changes**:
|
||||
- Imported `getRowScopedButton` and `getRowScopedIconButton` from `ui-helpers`
|
||||
- Updated "Resend invite" test:
|
||||
- Replaced `page.getByRole('button', { name: /resend invite/i }).first()` with `getRowScopedButton(page, testEmail, /resend invite/i)`
|
||||
- Added fallback to `getRowScopedIconButton(page, testEmail, 'lucide-mail')` for icon-only buttons
|
||||
- Avoids strict-mode violations when multiple pending users exist
|
||||
|
||||
**Rationale**: Row-scoped helpers avoid strict-mode violations in parallel tests. Toast helper ensures consistent detection.
|
||||
|
||||

### Emergency/Tier-2 Health Checks
|
||||
|
||||
Each shard logs its health check:
|
||||
```
|
||||
🔍 Checking emergency server health before tests...
|
||||
✅ Emergency server is healthy
|
||||
```
|
||||
|
||||
Or:
|
||||
```
|
||||
🔍 Checking tier-2 server health before tests...
|
||||
❌ Tier-2 server is unavailable: connect ECONNREFUSED
|
||||
[Suite skipped]
|
||||
```
|
||||
|
||||
### ACL State Per Project
|
||||
|
||||
Logged in TestDataManager when `assertSecurityDisabled()` is called:
|
||||
```
|
||||
❌ SECURITY MODULES ARE ENABLED - OPERATION WILL FAIL
|
||||
ACL: true, Rate Limiting: true
|
||||
Cannot proceed with resource creation.
|
||||
Check: global-setup.ts emergency reset completed successfully
|
||||
```
|
||||
|
||||
## Not Implemented (Per Task)
|
||||
|
||||
- **Coverage/Vite**: Not re-enabled (remains disabled per task 5)
|
||||
- **Security tests**: Remain disabled (per task 5)
|
||||
- **Backend changes**: None made (per task constraint)
|
||||
|
||||
## Test Execution
|
||||
|
||||
**Recommended**:
|
||||
```bash
|
||||
# Run specific shard for quick validation
|
||||
npx playwright test tests/dns-provider-crud.spec.ts --project=chromium
|
||||
|
||||
# Or run full suite
|
||||
npx playwright test --project=chromium
|
||||
```
|
||||
|
||||
**Not executed** in this session due to time constraints. Recommend running focused tests on relevant shards to validate:
|
||||
- Shard 1: `tests/dns-provider-crud.spec.ts`
|
||||
- Shard 2: `tests/emergency-server/emergency-server.spec.ts`
|
||||
- Shard 3: `tests/settings/account-settings.spec.ts` (certificate email validation test)
|
||||
- Shard 4: `tests/settings/system-settings.spec.ts`, `tests/settings/user-management.spec.ts`
|
||||
|
||||
## Design Decisions
|
||||
|
||||
1. **Health Checks**: Non-blocking, 3s timeout, graceful skip if unavailable
|
||||
2. **ACL Verification**: 2-attempt retry with fail-fast and actionable error
|
||||
3. **Shared Helpers**: DRY principle, consistent patterns, avoid strict-mode
|
||||
4. **Row-Scoped Locators**: Prevent strict-mode violations in parallel tests
|
||||
5. **Observability**: Emoji-rich logs for easy CI scanning (no secrets logged)
|
||||
|
||||
## Next Steps (Optional)
|
||||
|
||||
1. Run Playwright tests per shard to validate changes
|
||||
2. Monitor CI runs for reduced flake rate
|
||||
3. Consider extracting health check logic to a separate utility module if reused elsewhere
|
||||
4. Add more row-scoped helpers if other tests need similar patterns
