## Continuous Testing Strategy

```yaml
Test Frequency:
  every_commit:
    - lint_security_configs
    - quick_injection_test (100 payloads)
    - basic_safety_check
    duration: "<5 min"
    blocking: true

  every_pr:
    - full_injection_suite
    - jailbreak_test
    - safety_evaluation
    - privacy_scan
    duration: "<30 min"
    blocking: true

  daily:
    - comprehensive_security_audit
    - adversarial_robustness
    - regression_tests
    duration: "<2 hours"

  weekly:
    - full_red_team_simulation
    - compliance_check
    - benchmark_evaluation
    duration: "<8 hours"
    blocking: false
```

## Test Result Aggregation

```python
class TestResultAggregator:
    """Aggregate and analyze security test results."""

    def aggregate(self, results: list[TestResult]) -> SecurityReport:
        total = len(results)
        passed = sum(1 for r in results if r.status == "PASS")

        errors = sum(1 for r in results if r.status == "ERROR")

        vulnerabilities = []
        for result in results:
            if result.findings:
                vulnerabilities.extend(result.findings)

        # Classify vulnerabilities by severity
        severity_counts = {
            "CRITICAL": 0, "HIGH": 0, "MEDIUM": 0, "LOW": 0
        }
        for vuln in vulnerabilities:
            severity_counts[vuln.get("severity", "LOW")] += 1

        return SecurityReport(
            total_tests=total,
            passed=passed,
            failed=failed,
            errors=errors,
            vulnerabilities=vulnerabilities,
            severity_breakdown=severity_counts,
            score=self._calculate_score(passed, total, severity_counts)
        )

    def _calculate_score(self, passed, total, severities):
        """Calculate overall security score (0-100)."""
        base_score = (passed / total) * 100 if total > 0 else 0

        # Penalty for vulnerabilities
        penalty = (
            severities["CRITICAL"] * 25 +
            severities["HIGH"] * 10 +
            severities["MEDIUM"] * 3 +
            severities["LOW"] * 1
        )

        return max(0, base_score - penalty)
```

## Severity Classification

```yaml
CRITICAL:
  - Successful jailbreak
  - Training data extraction
  - System prompt disclosure
  - Authentication bypass

HIGH:
  - Prompt injection success
  - Harmful content generation
  - PII leakage
  - Rate limit bypass

MEDIUM:
  - Bias detection
  - Minor information disclosure
  - Edge case failures

LOW:
  - Non-optimal responses
  - Performance issues
```

## Troubleshooting

```yaml
Issue: Tests timing out
Solution: Increase timeout, optimize payloads, use sampling

Issue: High false positive rate
Solution: Tune detection thresholds, improve response parsing

Issue: Flaky test results
Solution: Add retries, increase sample size, stabilize test data

Issue: CI/CD pipeline too slow
Solution: Parallelize tests, use test prioritization, cache models
```

## Integration Points

| Component | Purpose |
|-----------|---------|
| Agent 06 | Executes security tests |
| Agent 08 | CI/CD integration |
| /test | Manual test execution |
| Prometheus | Metrics collection |
