## Previous Report: WAF to Coraza Rename

**Status: ✅ PASS**

All tests pass after fixing test assertions to match the new UI. The rename from "WAF (Coraza)" to "Coraza" has been successfully implemented and verified.

---

## Test Results

### TypeScript Compilation

| Check | Status |
|-------|--------|
| `npm run type-check` | ✅ PASS |

**Output:** Clean compilation with no errors.

### Frontend Unit Tests

| Metric | Count |
|--------|-------|
| Test Files | 84 |
| Tests Passed | 728 |
| Tests Skipped | 2 |
| Tests Failed | 0 |
| Duration | ~61s |

**Initial Run:** 4 failures related to outdated test assertions
**After Fix:** All 728 tests passing

#### Issues Found and Fixed

1. **Security.test.tsx - Line 281**
   - **Issue:** Test expected card title `'WAF (Coraza)'` but UI shows `'Coraza'`
   - **Severity:** Low (test sync issue)
   - **Fix:** Updated assertion to expect `'Coraza'`

2. **Security.test.tsx - Lines 252-267 (WAF Controls describe block)**
   - **Issue:** Tests for `waf-mode-select` and `waf-ruleset-select` dropdowns that were removed from the Security page
   - **Severity:** Low (removed UI elements)
   - **Fix:** Removed the `WAF Controls` test suite as dropdowns are now on dedicated `/security/waf` page

### Lint Results

| Tool | Errors | Warnings |
|------|--------|----------|
| ESLint | 0 | 5 |

**Warnings (pre-existing, not related to this change):**

- `CrowdSecConfig.tsx:212` - React Hook useEffect missing dependencies

| Check | Status | Details |
|-------|--------|---------|
| Navigation shows "Coraza" | ✅ Verified | Line 70: `{ name: 'Coraza', path: '/security/waf', icon: '🛡️' }` |

---

## Changes Made During QA

### Test File Update: Security.test.tsx

```diff
- describe('WAF Controls', () => {
-   it('should change WAF mode', async () => { ... })
-   it('should change WAF ruleset', async () => { ... })
- })
+ // Note: WAF Controls tests removed - dropdowns moved to dedicated WAF config page (/security/waf)

- expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'WAF (Coraza)', 'Rate Limiting', 'Live Security Logs'])
+ expect(cardNames).toEqual(['CrowdSec', 'Access Control', 'Coraza', 'Rate Limiting', 'Live Security Logs'])
```

---

## Recommendations

1. **No blocking issues** - All changes are complete and verified.

2. **Pre-existing warnings** - Consider addressing the `@typescript-eslint/no-explicit-any` warnings in `CrowdSecConfig.tsx` and its test file in a future cleanup pass.

---

## Conclusion

The WAF to Coraza rename has been successfully implemented:

- ✅ UI displays "Coraza" in the Security dashboard card
- ✅ Navigation shows "Coraza" instead of "WAF"
- ✅ Dropdowns removed from main Security page (moved to dedicated config page)
- ✅ All 728 frontend tests pass
- ✅ TypeScript compiles without errors
- ✅ No new lint errors introduced
- ✅ All pre-commit hooks pass

**QA Approval:** ✅ Approved for merge

## Rate Limiter Test Infrastructure QA

**Date**: December 12, 2025
**Scope**: Rate limiter integration test infrastructure verification

### Files Verified

| File | Status |
|------|--------|
| `scripts/rate_limit_integration.sh` | ✅ PASS |
| `backend/integration/rate_limit_integration_test.go` | ✅ PASS |
| `.vscode/tasks.json` | ✅ PASS |

### Validation Results

#### 1. Shell Script: `rate_limit_integration.sh`

**Syntax Check**: `bash -n scripts/rate_limit_integration.sh`

- **Result**: ✅ No syntax errors detected

**ShellCheck Static Analysis**: `shellcheck --severity=warning`

- **Result**: ✅ No warnings or errors

**File Permissions**:

- **Result**: ✅ Executable (`-rwxr-xr-x`)
- **File Type**: Bourne-Again shell script, UTF-8 text

**Security Review**:

- ✅ Uses `set -euo pipefail` for strict error handling
- ✅ Uses `$(...)` for command substitution (not backticks)
- ✅ Proper quoting around variables
- ✅ Cleanup trap function properly defined
- ✅ Error handler (`on_failure`) captures debug info
- ✅ Temporary files cleaned up in cleanup function
- ✅ No hardcoded secrets or credentials
- ✅ Uses `mktemp` for temporary cookie file

#### 2. Go Integration Test: `rate_limit_integration_test.go`

**Build Verification**: `go build -tags=integration ./integration/...`

- **Result**: ✅ Compiles successfully

**Code Review**:

- ✅ Proper build tag: `//go:build integration`
- ✅ Backward-compatible build tag: `// +build integration`
- ✅ Uses `t.Parallel()` for concurrent test execution
- ✅ Context timeout of 10 minutes (appropriate for rate limit window tests)
- ✅ Captures combined output for debugging
- ✅ Validates key assertions in script output

#### 3. VS Code Tasks: `tasks.json`

**JSON Validation**: Strip JSONC comments, parse as JSON

- **Result**: ✅ Valid JSON structure

**New Tasks Verified**:

| Task Label | Command | Status |
|------------|---------|--------|
| `Rate Limit: Run Integration Script` | `bash ./scripts/rate_limit_integration.sh` | ✅ Valid |
| `Rate Limit: Run Integration Go Test` | `go test -tags=integration ./integration -run TestRateLimitIntegration -v` | ✅ Valid |

### Issues Found

**None** - All files pass syntax validation and security review.

### Recommendations

1. **Documentation**: Consider adding inline comments to the Go test explaining the expected test flow for future maintainers.

2. **Timeout Tuning**: The 10-minute timeout in the Go test is generous. If tests consistently complete faster, consider reducing to 5 minutes.

3. **CI Integration**: Ensure the integration tests are properly gated in CI/CD pipelines to avoid running on every commit (Docker dependency).

### Rate Limiter Infrastructure Summary

The rate limiter test infrastructure has been verified and is **ready for use**. All three files pass syntax validation, compile/parse correctly, and follow security best practices.

**Overall Status**: ✅ **APPROVED**
