- Implemented comprehensive tests for security toggle handlers in `security_toggles_test.go`, covering enable/disable functionality for ACL, WAF, Cerberus, CrowdSec, and RateLimit. - Added sample JSON response for CrowdSec decisions in `lapi_decisions_response.json`. - Created aggressive preset configuration for CrowdSec in `preset_aggressive.json`. - Documented backend coverage, security fixes, and E2E testing improvements in `2026-02-02_backend_coverage_security_fix.md`. - Developed a detailed backend test coverage restoration plan in `current_spec.md` to address existing gaps and improve overall test coverage to 86%+.

# Backend Coverage, Security & E2E Fixes
|
|
|
|
**Date**: 2026-02-02
|
|
**Context**: Remediation of critical security vulnerabilities, backend test coverage improvements, and cross-browser E2E stability.
|
|
|
|
## 1. Architectural Constraint: Concrete Types vs Interfaces
|
|
|
|
### Problem
|
|
Initial attempts to increase test coverage for `ConfigLoader` and `ConfigManager` relied on mocking interfaces (`IConfigLoader`, `IConfigManager`). This approach proved problematic:
|
|
1. **Brittleness**: Mocks required constant updates whenever internal implementation details changed.
|
|
2. **False Confidence**: Mocks masked actual integration issues, particularly with file system interactions.
|
|
3. **Complexity**: The setup for mocks became more complex than the code being tested.
|
|
|
|
### Solution: Real Dependency Pattern
|
|
We shifted strategy to test **concrete types** instead of mocks for these specific components.
|
|
- **Why**: `ConfigLoader` and `ConfigManager` are "leaf" nodes in the dependency graph responsible for IO. Testing them with real (temporary) files system operations provides higher value.
|
|
- **Implementation**:
|
|
- Tests now create temporary directories using `t.TempDir()`.
|
|
- Concrete `NewConfigLoader` and `NewConfigManager` are instantiated.
|
|
- Assertions verify actual file creation and content on disk.
|
|
|
|
## 2. Security Fix: SafeJoin Remediation
|
|
|
|
### Vulnerability
|
|
Three critical vulnerabilities were identified where `filepath.Join` was used with user-controlled input, creating a risk of Path Traversal attacks.
|
|
|
|
**Locations:**
|
|
1. `backend/internal/caddy/config_loader.go`
|
|
2. `backend/internal/caddy/config_manager.go`
|
|
3. `backend/internal/caddy/import_handler.go`
|
|
|
|
### Fix
|
|
Replaced all risky `filepath.Join` calls with `utils.SafeJoin`.
|
|
|
|
**Mechanism**:
|
|
`utils.SafeJoin(base, path)` performs the following checks:
|
|
1. Joins the paths.
|
|
2. Cleans the resulting path.
|
|
3. Verifies that the resulting path still has the `base` path as a prefix.
|
|
4. Returns an error if the path attempts to traverse outside the base.
|
|
|
|
## 3. E2E Fix: WebKit/Firefox Switch Interaction
|
|
|
|
### Issue
|
|
E2E tests involving the `Switch` component (shadcn/ui) were reliably passing in Chromium but failing in WebKit (Safari) and Firefox.
|
|
- **Symptoms**: Timeouts, `click intercepted` errors, or assertions failing because the switch state didn't change.
|
|
- **Root Cause**: The underlying `<input type="checkbox">` is often visually hidden or covered by the styled toggle element. Chromium's event dispatching is slightly more forgiving, while WebKit/Firefox adhere strictly to visibility and hit-testing rules.
|
|
|
|
### Fix
|
|
Refactored `tests/utils/ui-helpers.ts` to improve interaction reliability.
|
|
|
|
1. **Semantic Clicks**: Instead of trying to force-click the input or specific coordinates, we now locate the accessible label or the wrapper element that handles the click event.
|
|
2. **Explicit State Verification**: Replaced arbitrary `waitForTimeout` calls with smart polling assertions:
|
|
```typescript
|
|
// Before
|
|
await toggle.click();
|
|
await page.waitForTimeout(500);
|
|
|
|
// After
|
|
await toggle.click();
|
|
await expect(toggle).toBeChecked({ timeout: 5000 });
|
|
```
|
|
3. **Result**: 100% pass rate across all three browser engines for System Settings and User Management tests.
