🧪 Testing and Validation

The OpenStack DevOps Suite includes comprehensive testing and validation capabilities to ensure reliable hybrid deployments across VM and Kubernetes environments.

Test Suite Overview

Test Script	Purpose	Coverage
`test-hybrid-deployment.sh`	Comprehensive system testing	All components, configs, connectivity
`test-performance.sh`	Load and performance testing	Response times, scalability, resource usage
`test-ssl-certificates.sh`	SSL certificate validation	cert-manager, HTTPS endpoints, DNS
`integration-tests.yml`	Cross-platform integration	VM/K8s compatibility, service health

Running Tests

1. Pre-Deployment Validation

# Validate all configurations before deployment
./scripts/test-hybrid-deployment.sh --pre-deployment

# Check prerequisites and configurations
./scripts/test-hybrid-deployment.sh --validate-configs

2. Post-Deployment Testing

# Full system validation after deployment
./scripts/test-hybrid-deployment.sh --post-deployment

# Test specific deployment type
./scripts/test-hybrid-deployment.sh --deployment-type vm
./scripts/test-hybrid-deployment.sh --deployment-type kubernetes
./scripts/test-hybrid-deployment.sh --deployment-type hybrid

3. Performance Testing

# Basic performance testing
./scripts/test-performance.sh

# Load testing with custom parameters
./scripts/test-performance.sh --concurrent-users 50 --duration 300

# Stress testing
./scripts/test-performance.sh --stress-test

4. SSL Certificate Testing

# Validate SSL certificates and HTTPS endpoints
./scripts/test-ssl-certificates.sh

# Test specific domain
./scripts/test-ssl-certificates.sh --domain yourdomain.com

# Monitor certificate status
./scripts/test-ssl-certificates.sh --monitor

5. Integration Testing

# Run Ansible-based integration tests
ansible-playbook playbooks/integration-tests.yml

# Test specific environment
ansible-playbook playbooks/integration-tests.yml --extra-vars "deployment_type=kubernetes"

Automated Testing in CI/CD

The Jenkins CI/CD pipeline automatically runs tests at different stages:

Validation Stage: Configuration and syntax checks
Verify Stage: Service connectivity and health checks
Performance Stage: Basic load testing (optional)

Test Reports

Test results are automatically generated in multiple formats:

# View latest test results
cat results/test-results-$(date +%Y%m%d).log

# SSL test results
cat results/ssl-test-results-$(date +%Y%m%d).log

# Performance reports
cat results/performance-results-$(date +%Y%m%d)/test.log

Troubleshooting Tests

Common test failures and solutions:

Issue	Cause	Solution
SSL test failures	DNS not configured	Update DNS records or use `--skip-dns`
K8s connectivity	Kubeconfig missing	Run `kubectl config current-context`
VM service timeout	Services not ready	Wait for services to start, check logs
Performance issues	Resource constraints	Scale resources or adjust test parameters

For detailed troubleshooting, see Testing Documentation.
