# Test Coverage Plan - 85%+ Coverage Target
# DNS Routes Implementation Plan
**Last Updated:** January 7, 2026
This document outlines the comprehensive plan to achieve 85%+ test coverage, addressing 457 lines of missing coverage across 10 files.
**Last Updated:** January 8, 2026
**Status:** 🟡 READY FOR IMPLEMENTATION
**Priority:** P1 - Navigation broken
---
## Section 0: ACTIVE - Test Failure Remediation Plan - PR #460 + #461 + CI Run #20773147447
## Problem Statement
**Status:** 🔴 CRITICAL - 30 Tests Failing in CI
**Created:** January 7, 2026
**Updated:** January 7, 2026 (Added PR #460 + CI failures)
**Priority:** P0 (Blocking PR #461)
**Context:** DNS Challenge Multi-Credential Support + Additional Test Failures
The `Layout.tsx` navigation was updated to include a DNS menu with children:
- `/dns` (parent)
- `/dns/providers`
- `/dns/plugins`
### Executive Summary
However, no corresponding routes were added to `App.tsx`, causing React Router errors:
```
No routes matched location "/dns/providers"
No routes matched location "/dns/plugins"
No routes matched location "/dns/"
```
Comprehensive remediation plan covering test failures from multiple sources:
- **PR #461** (24 tests): DNS Challenge multi-credential support
- **PR #460 Test Output** (5 tests): Backend handler failures
- **CI Run #20773147447** (1 test): Frontend timeout
---
**Total:** 30 unique test failures categorized into 5 root causes:
1. **DNS Provider Registry Not Initialized** - Critical blocker for 18 tests
2. **Credential Field Name Mismatches** - Affects 4 service tests
3. **Security Handler Error Handling** - 1 test returning 500 instead of 400
4. **Security Settings Database Override** - 5 tests failing due to record not found
5. **Certificate Deletion Race Condition** - 1 test with database locking
6. **Frontend Test Timeout** - 1 test with race condition
## Current State Analysis
### Root Causes Identified
### Layout.tsx Navigation (Lines 64-69)
```tsx
{ name: t('navigation.dns'), path: '/dns', icon: '☁️', children: [
{ name: t('navigation.dnsProviders'), path: '/dns/providers', icon: '🧭' },
{ name: t('navigation.plugins'), path: '/dns/plugins', icon: '🔌' },
] },
```
#### 1. DNS Provider Registry Not Initialized (CRITICAL)
- **Impact:** 18 tests failing (credential handlers + Caddy tests)
- **Issue:** `dnsprovider.Global().Get()` returns not found
- **Fix:** Create test helper to initialize registry with all providers
### App.tsx Current Routes (Lines 64-66)
The DNS-related route currently exists as:
```tsx
<Route path="dns-providers" element={<DNSProviders />} />
```
#### 2. Credential Field Name Inconsistencies
- **Impact:** 4 DNS provider service tests
- **Providers Affected:** hetzner (api_key→api_token), digitalocean (auth_token→api_token), dnsimple (oauth_token→api_token)
- **Fix:** Update test data field names
### Existing Page Components
| Component | Path | Status |
|-----------|------|--------|
| `DNSProviders.tsx` | `/pages/DNSProviders.tsx` | ✅ Exists |
| `Plugins.tsx` | `/pages/Plugins.tsx` | ✅ Exists |
#### 3. Security Handler Returns 500 for Invalid Input
- **Impact:** 1 security audit test
- **Issue:** Missing input validation before database operations
- **Fix:** Add validation returning 400 for malicious inputs
### Pattern Reference: Nested Routes
#### 4. Security Settings Database Override Not Working (NEW - PR #460)
- **Impact:** 5 security handler tests
- **Tests Failing:**
- `TestSecurityHandler_ACL_DBOverride`
- `TestSecurityHandler_CrowdSec_Mode_DBOverride`
- `TestSecurityHandler_GetStatus_RespectsSettingsTable` (5 sub-tests)
- `TestSecurityHandler_GetStatus_WAFModeFromSettings`
- `TestSecurityHandler_GetStatus_RateLimitModeFromSettings`
- **Issue:** `GetStatus` handler returns "record not found" when querying `security_configs` table
- **Root Cause:** Handler queries `security_configs` table which is empty in tests, but tests expect settings from `settings` table to override config
- **Fix:** Ensure handler checks `settings` table first before falling back to `security_configs`
**Settings Pattern** (Lines 79-87 in App.tsx):
```tsx
<Route path="settings" element={<Settings />}>
<Route index element={<SystemSettings />} />
<Route path="system" element={<SystemSettings />} />
<Route path="notifications" element={<Notifications />} />
<Route path="smtp" element={<SMTPSettings />} />
<Route path="crowdsec" element={<Navigate to="/security/crowdsec" replace />} />
<Route path="account" element={<Account />} />
<Route path="account-management" element={<UsersPage />} />
</Route>
```
#### 5. Certificate Deletion Database Lock (NEW - PR #460)
- **Impact:** 1 test (`TestDeleteCertificate_CreatesBackup`)
- **Issue:** `database table is locked: ssl_certificates` causing 500 error
- **Root Cause:** SQLite in-memory database lock contention when backup and delete happen in rapid succession
- **Fix:** Add proper transaction handling or retry logic with backoff
**Settings.tsx Structure**:
- Uses `<Outlet />` to render child routes
- Provides tab navigation UI for child pages
- Wraps content in `PageShell` component
#### 6. Frontend LiveLogViewer Test Timeout (NEW - CI #20773147447)
- **Impact:** 1 test (`LiveLogViewer.test.tsx:374` - "displays blocked requests with special styling")
- **Issue:** Test times out after 5000ms waiting for DOM elements
- **Root Cause:** Multiple assertions in single `waitFor` block + complex regex matching + async state update timing
- **Fix:** Split assertions into separate `waitFor` calls or use `findBy` queries
**Tasks Pattern** (Lines 89-98 in App.tsx):
```tsx
<Route path="tasks" element={<Tasks />}>
<Route index element={<Backups />} />
<Route path="backups" element={<Backups />} />
<Route path="logs" element={<Logs />} />
<Route path="import">
<Route path="caddyfile" element={<ImportCaddy />} />
<Route path="crowdsec" element={<ImportCrowdSec />} />
</Route>
</Route>
```

## Implementation Plan
### Phase 1: Create DNS Parent Page
**File**: `frontend/src/pages/DNS.tsx` (NEW)
```tsx
import { Link, Outlet, useLocation } from 'react-router-dom'
import { useTranslation } from 'react-i18next'
import { PageShell } from '../components/layout/PageShell'
import { cn } from '../utils/cn'
import { Cloud, Puzzle } from 'lucide-react'
export default function DNS() {
const { t } = useTranslation()
const location = useLocation()
const isActive = (path: string) => location.pathname === path
const navItems = [
{ path: '/dns/providers', label: t('navigation.dnsProviders'), icon: Cloud },
{ path: '/dns/plugins', label: t('navigation.plugins'), icon: Puzzle },
]
return (
<PageShell
title={t('dns.title')}
description={t('dns.description')}
actions={
<div className="flex items-center gap-2 text-content-muted">
<Cloud className="h-5 w-5" />
</div>
}
>
{/* Tab Navigation */}
<nav className="flex items-center gap-1 p-1 bg-surface-subtle rounded-lg w-fit">
{navItems.map(({ path, label, icon: Icon }) => (
<Link
key={path}
to={path}
className={cn(
'flex items-center gap-2 px-4 py-2 rounded-md text-sm font-medium transition-all duration-fast',
isActive(path)
? 'bg-surface-elevated text-content-primary shadow-sm'
: 'text-content-secondary hover:text-content-primary hover:bg-surface-muted'
)}
>
<Icon className="h-4 w-4" />
{label}
</Link>
))}
</nav>
{/* Content Area */}
<div className="bg-surface-elevated border border-border rounded-lg p-6">
<Outlet />
</div>
</PageShell>
)
}
```
---
### Phase 2: Update App.tsx Routes
**File**: `frontend/src/App.tsx`
#### Changes Required:
1. **Add lazy import** (after line 24):
```tsx
const DNS = lazy(() => import('./pages/DNS'))
```
2. **Replace single dns-providers route** (line 66):
**REMOVE**:
```tsx
<Route path="dns-providers" element={<DNSProviders />} />
```
**ADD** (after the domains route, ~line 65):
```tsx
{/* DNS Routes */}
<Route path="dns" element={<DNS />}>
<Route index element={<DNSProviders />} />
<Route path="providers" element={<DNSProviders />} />
<Route path="plugins" element={<Plugins />} />
</Route>
{/* Legacy redirect for old bookmarks */}
<Route path="dns-providers" element={<Navigate to="/dns/providers" replace />} />
```
#### Full Diff Preview:
```diff
const Dashboard = lazy(() => import('./pages/Dashboard'))
const ProxyHosts = lazy(() => import('./pages/ProxyHosts'))
const RemoteServers = lazy(() => import('./pages/RemoteServers'))
+const DNS = lazy(() => import('./pages/DNS'))
const ImportCaddy = lazy(() => import('./pages/ImportCaddy'))
```
```diff
<Route path="domains" element={<Domains />} />
<Route path="certificates" element={<Certificates />} />
- <Route path="dns-providers" element={<DNSProviders />} />
+
+ {/* DNS Routes */}
+ <Route path="dns" element={<DNS />}>
+ <Route index element={<DNSProviders />} />
+ <Route path="providers" element={<DNSProviders />} />
+ <Route path="plugins" element={<Plugins />} />
+ </Route>
+
+ {/* Legacy redirect for old bookmarks */}
+ <Route path="dns-providers" element={<Navigate to="/dns/providers" replace />} />
+
<Route path="security" element={<Security />} />
```
---
### Phase 3: Update DNSProviders.tsx
The `DNSProviders.tsx` component currently uses `PageShell` directly. When rendered inside `DNS.tsx`, it will be wrapped twice. We need to remove `PageShell` since the parent DNS component provides it.
**File**: `frontend/src/pages/DNSProviders.tsx`
**Changes Required**:
```diff
-import { PageShell } from '../components/layout/PageShell'
+// PageShell removed - parent DNS component provides the shell
export default function DNSProviders() {
// ... existing state and handlers ...
- return (
- <PageShell
- title={t('dnsProviders.title')}
- description={t('dnsProviders.description')}
- actions={headerActions}
- >
+ return (
+ <div className="space-y-6">
+ {/* Header with Add Button */}
+ <div className="flex justify-end">
+ {headerActions}
+ </div>
+
{/* Info Alert */}
<Alert variant="info" icon={Cloud}>
...
</Alert>
{/* Loading State */}
...
{/* Empty State */}
...
{/* Provider Cards Grid */}
...
{/* Add/Edit Form Dialog */}
...
- </PageShell>
+ </div>
)
}
```
---
### Phase 4: Update Plugins.tsx
**File**: `frontend/src/pages/Plugins.tsx`
Apply the same pattern - remove `PageShell` wrapper since `DNS.tsx` provides it.
**Changes Required**:
```diff
-import { PageShell } from '../components/layout/PageShell'
+// PageShell removed - parent DNS component provides the shell
export default function Plugins() {
// ... existing state and handlers ...
- return (
- <PageShell
- title={t('plugins.title', 'DNS Provider Plugins')}
- description={t('plugins.description', '...')}
- actions={headerActions}
- >
+ return (
+ <div className="space-y-6">
+ {/* Header with Reload Button */}
+ <div className="flex justify-end">
+ {headerActions}
+ </div>
+
{/* Info Alert */}
...
{/* Loading State */}
...
{/* Empty State */}
...
{/* Built-in Plugins Section */}
...
{/* External Plugins Section */}
...
{/* Metadata Modal */}
...
- </PageShell>
+ </div>
)
}
```
---
### Phase 5: Add i18n Translation Keys
**File**: `frontend/src/locales/en/translation.json`
Add to the `navigation` section (around line 54):
```json
"dns": "DNS",
```
Add new section for DNS parent page (after `dnsProviders` section):
```json
"dns": {
"title": "DNS Management",
"description": "Manage DNS providers and plugins for certificate automation"
},
```
**Files to update** (all locale files):
- `frontend/src/locales/en/translation.json`
- `frontend/src/locales/de/translation.json`
- `frontend/src/locales/es/translation.json`
- `frontend/src/locales/fr/translation.json`
- `frontend/src/locales/zh/translation.json`
---
### Phase 6: Remove admin/plugins Route (Cleanup)
**File**: `frontend/src/App.tsx`
The current route at line 76:
```tsx
<Route path="admin/plugins" element={<Plugins />} />
```
This should be **replaced** with a redirect for backwards compatibility:
```tsx
<Route path="admin/plugins" element={<Navigate to="/dns/plugins" replace />} />
```
---
## Test Updates
### New Test File: DNS.test.tsx
**File**: `frontend/src/pages/__tests__/DNS.test.tsx` (NEW)
```tsx
import { describe, it, expect, vi } from 'vitest'
import { screen, within } from '@testing-library/react'
import DNS from '../DNS'
import { renderWithQueryClient } from '../../test-utils/renderWithQueryClient'
vi.mock('react-i18next', () => ({
useTranslation: () => ({
t: (key: string) => {
const translations: Record<string, string> = {
'dns.title': 'DNS Management',
'dns.description': 'Manage DNS providers and plugins',
'navigation.dnsProviders': 'DNS Providers',
'navigation.plugins': 'Plugins',
}
return translations[key] || key
},
}),
}))
describe('DNS page', () => {
it('renders DNS management page with navigation tabs', async () => {
renderWithQueryClient(<DNS />, { routeEntries: ['/dns/providers'] })
expect(await screen.findByText('DNS Management')).toBeInTheDocument()
expect(screen.getByText('DNS Providers')).toBeInTheDocument()
expect(screen.getByText('Plugins')).toBeInTheDocument()
})
it('highlights active tab based on route', async () => {
renderWithQueryClient(<DNS />, { routeEntries: ['/dns/providers'] })
const nav = screen.getByRole('navigation')
const providersLink = within(nav).getByText('DNS Providers').closest('a')
// Active tab should have the elevated style class
expect(providersLink).toHaveClass('bg-surface-elevated')
})
it('provides tab navigation links', async () => {
renderWithQueryClient(<DNS />, { routeEntries: ['/dns'] })
const providersLink = screen.getByRole('link', { name: /dns providers/i })
const pluginsLink = screen.getByRole('link', { name: /plugins/i })
expect(providersLink).toHaveAttribute('href', '/dns/providers')
expect(pluginsLink).toHaveAttribute('href', '/dns/plugins')
})
})
```
### Update Existing Tests
**File**: `frontend/src/pages/__tests__/Plugins.test.tsx`
Add route entry to test context since Plugins is now a child route:
```diff
- renderWithQueryClient(<Plugins />)
+ renderWithQueryClient(<Plugins />, { routeEntries: ['/dns/plugins'] })
```
