Deployment Testing Strategy

This document outlines the strategy for testing deployments to ensure successful and reliable deployments to production and staging environments.

Current Deployment Process

Deployment Scripts

• Primary Script: deploy/ssh/deploy-remote.sh
• Python Version: deploy/ssh/deploy-remote.py
• Target Server: 95.111.206.155 (root user)
• Configuration: Git-ignored deployment configuration

Current Capabilities

• SSH-based deployment
• Environment-specific configurations (production, staging)
• Dry-run mode for testing
• Key management system
• Configuration validation

Deployment Testing Strategy

1. Pre-Deployment Testing

Local Validation

# Run all tests before deployment
./scripts/run-reliable-e2e-tests.py
pytest tests/unit/
pytest tests/integration/

Configuration Validation

# Validate deployment configuration
deploy/ssh/deploy-remote.sh -e production --dry-run --verbose

2. Staging Environment Testing

Recommended Enhancement

Create a staging environment for pre-production testing:

1. Staging Server: Separate server for testing deployments
2. Smoke Tests: Automated tests that verify deployment success
3. Integration Tests: Test with staging SCADA/optimizer services
4. Rollback Testing: Verify rollback procedures work

3. Post-Deployment Testing

Current Manual Process

After deployment, manually verify:

• Services are running
• Health endpoints respond
• Basic functionality works

Recommended Automated Process

Create automated smoke tests:

# Post-deployment smoke tests
./scripts/deployment-smoke-tests.sh

Proposed Deployment Test Structure

Directory Structure

tests/
├── deployment/              # Deployment-specific tests
│   ├── smoke_tests.py      # Post-deployment smoke tests
│   ├── staging_tests.py    # Staging environment tests
│   └── rollback_tests.py   # Rollback procedure tests
└── e2e/                    # Existing e2e tests (mock-dependent)

Deployment Test Categories

1. Smoke Tests (tests/deployment/smoke_tests.py)

• Purpose: Verify basic functionality after deployment
• Execution: Run on deployed environment
• Tests:
  • Service health checks
  • API endpoint availability
  • Database connectivity
  • Basic workflow validation

2. Staging Tests (tests/deployment/staging_tests.py)

• Purpose: Full test suite on staging environment
• Execution: Run on staging server
• Tests:
  • Complete e2e workflows
  • Integration with staging services
  • Performance validation
  • Security compliance

3. Rollback Tests (tests/deployment/rollback_tests.py)

• Purpose: Verify rollback procedures work
• Execution: Test rollback scenarios
• Tests:
  • Database rollback
  • Configuration rollback
  • Service restart procedures

Implementation Plan

Phase 1: Smoke Tests

1. Create tests/deployment/smoke_tests.py
2. Add basic health and connectivity tests
3. Integrate with deployment script
4. Run automatically after deployment

Phase 2: Staging Environment

1. Set up staging server
2. Configure staging services
3. Create staging-specific tests
4. Run full test suite on staging

Phase 3: Automated Deployment Pipeline

1. Integrate deployment tests with CI/CD
2. Add automated rollback triggers
3. Implement deployment metrics
4. Create deployment dashboards

Current Deployment Script Usage

Dry Run (Safe Testing)

# Test deployment without actually deploying
deploy/ssh/deploy-remote.sh -e production --dry-run --verbose

Actual Deployment

# Deploy to production
deploy/ssh/deploy-remote.sh -e production

With Custom Configuration

# Use custom configuration
deploy/ssh/deploy-remote.sh -e production -c deploy/config/custom.yaml

Integration with Existing Tests

Mock Services vs Real Deployment

• Mock Services: Use for development and local testing
• Staging Services: Use for pre-production testing
• Production Services: Use for post-deployment verification

Test Execution Flow

Local Development → Mock Services → Unit/Integration Tests
    ↓
Staging Deployment → Staging Services → Deployment Tests
    ↓
Production Deployment → Production Services → Smoke Tests

Security Considerations

Deployment Security

• SSH key management
• Configuration encryption
• Access control
• Audit logging

Test Data Security

• Use test data in staging
• Never use production data in tests
• Secure test credentials
• Clean up test data

Monitoring and Metrics

Deployment Metrics

• Deployment success rate
• Rollback frequency
• Test coverage percentage
• Performance impact

Health Monitoring

• Service uptime
• Response times
• Error rates
• Resource utilization

Next Steps

Immediate Actions

1. Create basic smoke tests in tests/deployment/
2. Update deployment script to run smoke tests
3. Document deployment verification procedures

Medium Term

1. Set up staging environment
2. Create comprehensive deployment test suite
3. Integrate with CI/CD pipeline

Long Term

1. Implement automated rollback
2. Create deployment dashboards
3. Add performance benchmarking
4. Implement canary deployments
