# TRUST 5 Validation Framework

Comprehensive TRUST 5 quality framework validation for enterprise code quality assurance.

## Overview

The TRUST 5 framework validates five core quality principles:
- Testable - Test coverage and quality
- Readable - Code clarity and maintainability
- Unified - Consistent patterns and standards
- Secured - Security compliance (OWASP)
- Trackable - Version control and audit trails

## TRUST 5 Validator Implementation

```python
class TRUST5Validator:
 """Comprehensive TRUST 5 quality framework validation"""

 VALIDATORS = {
 "testable": TestableValidator(),
 "readable": ReadableValidator(),
 "unified": UnifiedValidator(),
 "secured": SecuredValidator(),
 "trackable": TrackableValidator()
 }

 async def validate(self, codebase: str, thresholds: Dict[str, float]) -> TRUST5Result:
 """Execute complete TRUST 5 validation"""

 results = {}

 for principle, validator in self.VALIDATORS.items():
 result = await validator.validate(
 codebase=codebase,
 threshold=thresholds.get(principle, 0.8)
 )
 results[principle] = result

 # Calculate overall TRUST 5 score
 overall_score = sum(r.score for r in results.values()) / len(results)

 return TRUST5Result(
 principles=results,
 overall_score=overall_score,
 passed=overall_score >= thresholds.get("overall", 0.85),
 recommendations=self._generate_trust5_recommendations(results)
 )

class TestableValidator:
 """Test-first principle validation"""

 async def validate(self, codebase: str, threshold: float) -> ValidationResult:
 """Validate test coverage and quality"""

 # Check test coverage
 coverage_result = await self._analyze_test_coverage(codebase)

 # Validate test quality
 test_quality = await self._analyze_test_quality(codebase)

 # Check test structure
 test_structure = await self._validate_test_structure(codebase)

 score = (coverage_result.score * 0.5 +
 test_quality.score * 0.3 +
 test_structure.score * 0.2)

 return ValidationResult(
 score=score,
 passed=score >= threshold,
 details={
 "coverage": coverage_result,
 "quality": test_quality,
 "structure": test_structure
 },
 recommendations=self._generate_testing_recommendations(
 coverage_result, test_quality, test_structure
 )
 )

class SecuredValidator:
 """Security principle validation with OWASP compliance"""

 async def validate(self, codebase: str, threshold: float) -> ValidationResult:
 """Validate security compliance and vulnerabilities"""

 # OWASP Top 10 validation
 owasp_result = await self._validate_owasp_compliance(codebase)

 # Security best practices
 security_practices = await self._validate_security_practices(codebase)

 # Dependency vulnerability scan
 dependency_scan = await self._scan_dependency_vulnerabilities(codebase)

 # Code security patterns
 code_security = await self._analyze_code_security(codebase)

 score = (owasp_result.score * 0.4 +
 security_practices.score * 0.3 +
 dependency_scan.score * 0.2 +
 code_security.score * 0.1)

 return ValidationResult(
 score=score,
 passed=score >= threshold,
 details={
 "owasp": owasp_result,
 "practices": security_practices,
 "dependencies": dependency_scan,
 "code_patterns": code_security
 },
 security_level=self._calculate_security_level(score),
 recommendations=self._generate_security_recommendations(
 owasp_result, security_practices, dependency_scan, code_security
 )
 )
```

## Configuration

```yaml
trust5_framework:
 enabled: true
 thresholds:
 overall: 0.85
 testable: 0.90
 readable: 0.80
 unified: 0.85
 secured: 0.90
 trackable: 0.80
```

## Quality Gate Pipeline

```python
async def quality_gate_pipeline():
 """Integrate quality validation into CI/CD pipeline"""

 # Initialize quality orchestrator
 quality_orchestrator = QualityOrchestrator.from_config("quality-config.yaml")

 # Run comprehensive quality analysis
 quality_result = await quality_orchestrator.analyze_codebase(
 path="src/",
 languages=["python", "typescript"],
 quality_threshold=0.85
 )

 # Quality gate validation
 if not quality_result.trust5_validation.passed:
 print(" Quality gate failed!")
 print(f"Overall score: {quality_result.overall_score:.2f}")

 # Print failed principles
 for principle, result in quality_result.trust5_validation.principles.items():
 if not result.passed:
 print(f" {principle}: {result.score:.2f} (threshold: 0.80)")

 # Exit with error code
 sys.exit(1)

 print(" Quality gate passed!")
```
