CSV-Parameterized Compliance Testing

Overview

CloudForge now supports CSV-based parameterized testing for compliance framework validation. This provides a declarative, version-controlled approach to defining test matrices that validate multi-layer defense-in-depth compliance.

Architecture

Test Data Flow

truth-table-generator.py
         ↓
compliance-test-matrix.csv (16 test cases)
         ↓
@CsvFileSource annotation
         ↓
testComplianceFrameworkIntegrationCsv()
         ↓
Multi-Layer Validation:
  - Layer 1: cdk-nag (construct-level)
  - Layer 2: CloudForge FrameworkRules (business logic)
  - Layer 3: cfn-guard (template-level policy)
  - Layer 4: AWS Config (runtime monitoring)

Test Matrix

The CSV test matrix is automatically generated by the truth table generator and includes:

• 4 Compliance Frameworks: SOC2, PCI-DSS, HIPAA, GDPR
• 2 Runtimes: EC2, FARGATE
• 2 Network Modes: public-no-nat, private-with-nat
• Total Test Cases: 16 (4 × 2 × 2)

All test cases use:

• Security Profile: PRODUCTION (required for compliance)
• SSL: Enabled (compliance requirement)
• Domain: Configured (for proper certificate validation)

Usage

Generating the CSV Test Matrix

cd cfc-testing
python3 scripts/truth-table-generator.py

This generates three files:

1. truth-table.json - Complete truth table (132 valid configurations)
2. truth-table-report.html - Interactive HTML report
3. compliance-test-matrix.csv - Compliance test matrix (16 test cases)

Running CSV-Based Tests

# Run only CSV-based compliance tests
mvn test -Dtest=TruthTableValidationTest#testComplianceFrameworkIntegrationCsv

# Run all truth table tests (including CSV tests)
mvn test -Dtest=TruthTableValidationTest

CSV Format

The generated CSV file follows this structure:

configName,runtime,securityProfile,domainConfig,sslConfig,subdomainConfig,authMode,networkMode,complianceFramework
EC2_PRODUCTION_SOC2_public-no-nat,EC2,PRODUCTION,with-domain,ssl-enabled,no-subdomain,none,public-no-nat,SOC2
EC2_PRODUCTION_SOC2_private-with-nat,EC2,PRODUCTION,with-domain,ssl-enabled,no-subdomain,none,private-with-nat,SOC2
FARGATE_PRODUCTION_SOC2_public-no-nat,FARGATE,PRODUCTION,with-domain,ssl-enabled,no-subdomain,none,public-no-nat,SOC2
...

Test Implementation

@CsvFileSource Test Method

@ParameterizedTest(name = "{0}")
@CsvFileSource(
    resources = "/compliance-test-matrix.csv",
    numLinesToSkip = 1  // Skip CSV header
)
void testComplianceFrameworkIntegrationCsv(
        String configName,
        String runtime,
        String securityProfile,
        String domainConfig,
        String sslConfig,
        String subdomainConfig,
        String authMode,
        String networkMode,
        String complianceFramework) {

    // 1. Create CDK stack
    // 2. Configure deployment context with compliance framework
    // 3. Synthesize CloudFormation template
    // 4. Run multi-layer validation (cdk-nag, FrameworkRules, cfn-guard, Config)
    // 5. Assert zero violations (except known gaps)
}

Key Benefits

1. Declarative Test Data

   • CSV format is human-readable and easy to modify
   • No need to understand Java/JUnit to add test cases
   • Simple to version control and review in PRs

2. Consistent Naming

   • Test names match configuration names across all tools
   • Easy to correlate failures across layers

3. Separation of Concerns

   • Test logic (Java) separate from test data (CSV)
   • Python script generates comprehensive matrices
   • Test code focuses on validation logic only

4. Comprehensive Coverage

   • Systematic testing of all compliance frameworks
   • Consistent test parameters across all cases
   • No manual test case authoring required

Multi-Layer Validation Status

Layer	Tool	Status	Details
Layer 1	cdk-nag	✅ Active	Applied for SOC2, PCI-DSS, HIPAA
Layer 2	CloudForge FrameworkRules	✅ Active	Custom business logic validation
Layer 3	cfn-guard	⚠️ Partial	HIPAA, PCI-DSS, SOC2 implemented; GDPR pending
Layer 4	AWS Config	✅ Validated	Config rule deployment verified

Validation Output Example

🔒 Testing compliance configuration (CSV): EC2_PRODUCTION_SOC2_public-no-nat [SOC2]
   Runtime: EC2
   Security: PRODUCTION
   Compliance: SOC2
   Data Source: compliance-test-matrix.csv

INFO: Applying cdk-nag validation (mode=enforce)
INFO:   ✓ Applied cdk-nag pack for SOC2
INFO: Applied 1 cdk-nag validation packs
INFO: Skipping CloudForge FrameworkRules validation (auditManagerEnabled = false)
INFO:   Note: cdk-nag validation still applied for enabled frameworks

   ✅ Compliance validation passed: SOC2

Files Modified/Created

Enhanced Files

1. truth-table-generator.py

   • Added ComplianceFramework enum (SOC2, PCI-DSS, HIPAA, GDPR)
   • Added generate_compliance_test_csv() method
   • Generates 16 test cases (4 frameworks × 2 runtimes × 2 network modes)

2. TruthTableValidationTest.java

   • Added @CsvFileSource import
   • Added testComplianceFrameworkIntegrationCsv() method
   • Kept existing @MethodSource tests for comparison

Generated Files

1. compliance-test-matrix.csv
   • 16 test cases + 1 header row
   • Automatically regenerated when truth-table-generator.py runs
   • Copied to cloudforge-api/src/test/resources/ for classpath access

Comparison: @CsvFileSource vs @MethodSource

@CsvFileSource Approach (NEW)

Pros:

• ✅ Declarative test data (easy to read/modify)
• ✅ Version-controlled CSV files
• ✅ Consistent with truth table generator
• ✅ Non-developers can add test cases
• ✅ Easy to diff in PRs

Cons:

• ⚠️ Requires CSV regeneration when dimensions change
• ⚠️ Less flexible for dynamic test generation

@MethodSource Approach (EXISTING)

Pros:

• ✅ Dynamic test generation (no files needed)
• ✅ Programmatic control over test parameters
• ✅ No CSV maintenance required

Cons:

• ⚠️ Test data buried in Java code
• ⚠️ Harder to visualize test matrix
• ⚠️ Requires Java knowledge to modify

Recommendation

Use @CsvFileSource for:

• Compliance framework testing (stable, well-defined matrix)
• Tests where non-developers need visibility
• Tests that benefit from version-controlled data

Use @MethodSource for:

• Dynamic test generation (changing dimensions)
• Tests requiring programmatic logic
• Quick prototyping without file management

Integration with CI/CD

GitHub Actions Workflow

The CSV-based tests are automatically run in CI/CD:

- name: Run compliance validation tests
  run: |
    cd cloudforge-api
    mvn test -Dtest=TruthTableValidationTest#testComplianceFrameworkIntegrationCsv

Test Report Generation

CI/CD generates detailed reports showing:

• Individual test pass/fail status
• Multi-layer validation results per framework
• cdk-nag violations (if any)
• cfn-guard policy violations (if any)
• Known compliance gaps vs. actual failures

Troubleshooting

CSV File Not Found

Error: resources = "/compliance-test-matrix.csv" not found

Solution: Regenerate CSV and ensure it's copied to test resources:

cd cfc-testing
python3 scripts/truth-table-generator.py
cp scripts/validation-results/compliance-test-matrix.csv ../cloudforge-api/src/test/resources/

Test Failures

Error: Compliance validation failed

Solution: Check validation layer logs:

1. cdk-nag: Look for "Applied N cdk-nag validation packs"
2. cfn-guard: Check "cfn-guard validation passed" messages
3. FrameworkRules: Review ComplianceValidationMatrix output

Known Gaps vs. Failures

The tests distinguish between:

• Known Gaps: Expected limitations marked with [KNOWN GAP] - reported as warnings
• Actual Failures: Unexpected violations - fail the test

Example:

⚠️  Known compliance gaps detected:
    [KNOWN GAP] GDPR: Data residency controls not yet implemented

✅ Compliance validation passed: GDPR (with 1 known gaps)
