# 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
```bash
# Run all tests before deployment
./scripts/run-reliable-e2e-tests.py
pytest tests/unit/
pytest tests/integration/
```
#### Configuration Validation
```bash
# 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:
```bash
# 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)
```bash
# Test deployment without actually deploying
deploy/ssh/deploy-remote.sh -e production --dry-run --verbose
```
### Actual Deployment
```bash
# Deploy to production
deploy/ssh/deploy-remote.sh -e production
```
### With Custom Configuration
```bash
# 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

# Testing Strategy
This document outlines the testing strategy for the Calejo Control Adapter project.
## Test Directory Structure
```
tests/
├── unit/ # Unit tests - test individual components in isolation
├── integration/ # Integration tests - test components working together
├── e2e/ # End-to-end tests - require external services (mocks)
├── fixtures/ # Test fixtures and data
├── utils/ # Test utilities
└── mock_services/ # Mock SCADA and optimizer services
```
## Test Categories
### 1. Unit Tests (`tests/unit/`)
- **Purpose**: Test individual functions, classes, and modules in isolation
- **Dependencies**: None or minimal (mocked dependencies)
- **Execution**: `pytest tests/unit/`
- **Examples**: Database clients, configuration validation, business logic
### 2. Integration Tests (`tests/integration/`)
- **Purpose**: Test how components work together
- **Dependencies**: May require database, but not external services
- **Execution**: `pytest tests/integration/`
- **Examples**: Database integration, protocol handlers working together
### 3. End-to-End Tests (`tests/e2e/`)
- **Purpose**: Test complete workflows with external services
- **Dependencies**: Require mock SCADA and optimizer services
- **Execution**: Use dedicated runner scripts
- **Examples**: Complete SCADA-to-optimizer workflows
### 4. Mock Services (`tests/mock_services/`)
- **Purpose**: Simulate external SCADA and optimizer services
- **Usage**: Started by e2e test runners
- **Ports**: SCADA (8081), Optimizer (8082)
## Test Runners
### For E2E Tests (Mock-Dependent)
```bash
# Starts mock services and runs e2e tests
./scripts/run-reliable-e2e-tests.py
# Quick mock service verification
./scripts/test-mock-services.sh
# Full test environment setup
./scripts/setup-test-environment.sh
```
### For Unit and Integration Tests
```bash
# Run all unit tests
pytest tests/unit/
# Run all integration tests
pytest tests/integration/
# Run specific test file
pytest tests/unit/test_database_client.py
```
## Deployment Testing
### Current Strategy
- **Deployment Script**: `deploy/ssh/deploy-remote.sh`
- **Purpose**: Deploy to production server (95.111.206.155)
- **Testing**: Manual verification after deployment
- **Separation**: Deployment is separate from automated testing
### Recommended Enhancement
To add automated deployment testing:
1. Create `tests/deployment/` directory
2. Add smoke tests that verify deployment
3. Run these tests after deployment
4. Consider using staging environment for pre-production testing
## Test Execution Guidelines
### When to Run Which Tests
- **Local Development**: Run unit tests frequently
- **Before Commits**: Run unit + integration tests
- **Before Deployment**: Run all tests including e2e
- **CI/CD Pipeline**: Run all test categories
### Mock Service Usage
- E2E tests require mock services to be running
- Use dedicated runners that manage service lifecycle
- Don't run e2e tests directly with pytest (they'll fail)
## Adding New Tests
1. **Unit Tests**: Add to `tests/unit/`
2. **Integration Tests**: Add to `tests/integration/`
3. **E2E Tests**: Add to `tests/e2e/` and update runners if needed
4. **Mock Services**: Add to `tests/mock_services/` if new services needed
## Best Practices
- Keep tests fast and isolated
- Use fixtures for common setup
- Mock external dependencies in unit tests
- Write descriptive test names
- Include both happy path and error scenarios
- Use retry logic for flaky network operations

ALTER SYSTEM SET work_mem = '64MB';
ALTER SYSTEM SET maintenance_work_mem = '512MB';
ALTER SYSTEM SET effective_cache_size = '6GB';
ALTER SYSTEM SET random_page_cost = 1.1;
-- Restart PostgreSQL
SELECT pg_reload_conf();
```
#### Index Optimization
```sql
-- Create performance indexes
CREATE INDEX idx_audit_log_timestamp ON compliance_audit_log(timestamp);
CREATE INDEX idx_audit_log_event_type ON compliance_audit_log(event_type);
CREATE INDEX idx_safety_limits_station ON safety_limits(station_id, pump_id);
```
### Application Tuning

```
### Data Synchronization
#### Real-time Data Flow
```python
class ProtocolDataSync:
def __init__(self):
self.data_cache = {}
self.protocol_servers = []
def update_setpoint(self, station_id: str, pump_id: str, setpoint: float):
"""Update setpoint across all protocol servers."""
# Update internal cache
self.data_cache[f"{station_id}.{pump_id}.setpoint"] = setpoint
# Propagate to all protocol servers
for server in self.protocol_servers:
server.update_setpoint(station_id, pump_id, setpoint)
```
#### Consistency Guarantees
- **Atomic Updates**: All-or-nothing updates
- **Order Preservation**: Sequential update processing
- **Conflict Resolution**: Last-write-wins strategy
- **Error Handling**: Graceful failure recovery
### Performance Optimization
#### Caching Strategy
```python
class ProtocolCache:
def __init__(self):
self.setpoint_cache = {}
self.status_cache = {}
self.cache_ttl = 60 # seconds
def get_setpoint(self, station_id: str, pump_id: str) -> Optional[float]:
"""Get cached setpoint value."""
key = f"{station_id}.{pump_id}"
if key in self.setpoint_cache:
cached_value, timestamp = self.setpoint_cache[key]
if time.time() - timestamp < self.cache_ttl:
return cached_value
return None
```
#### Connection Pooling
```python
class ConnectionPool:
def __init__(self, max_connections: int = 100):
self.max_connections = max_connections
self.active_connections = 0
self.connection_pool = []
```

# Calejo Control Adapter - Safety Framework
## Overview
The Calejo Control Adapter implements a comprehensive multi-layer safety framework designed to prevent equipment damage, operational hazards, and ensure reliable pump station operation under all conditions, including system failures, communication loss, and cyber attacks.
**Safety Philosophy**: "Safety First" - All setpoints must pass through safety enforcement before reaching SCADA systems.
## Multi-Layer Safety Architecture
### Three-Layer Safety Model
```
┌─────────────────────────────────────────────────────────┐
│ Layer 3: Optimization Constraints (Calejo Optimize) │
│ - Economic optimization bounds: 25-45 Hz │
│ - Energy efficiency constraints │
│ - Production optimization limits │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ Layer 2: Station Safety Limits (Control Adapter) │
│ - Database-enforced limits: 20-50 Hz │
│ - Rate of change limiting │
│ - Emergency stop integration │
│ - Failsafe mechanisms │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ Layer 1: Physical Hard Limits (PLC/VFD) │
│ - Hardware-enforced limits: 15-55 Hz │
│ - Physical safety mechanisms │
│ - Equipment protection │
└─────────────────────────────────────────────────────────┘
```
## Safety Components
### 1. Safety Limit Enforcer (`src/core/safety.py`)
#### Purpose
The Safety Limit Enforcer is the **LAST line of defense** before setpoints are exposed to SCADA systems. ALL setpoints MUST pass through this enforcer.
#### Key Features
- **Multi-Layer Limit Enforcement**:
- Hard operational limits (speed, level, power, flow)
- Rate of change limiting
- Emergency stop integration
- Failsafe mode activation
- **Safety Limit Types**:
```python
@dataclass
class SafetyLimits:
hard_min_speed_hz: float # Minimum speed limit (Hz)
hard_max_speed_hz: float # Maximum speed limit (Hz)
hard_min_level_m: Optional[float] # Minimum level limit (meters)
hard_max_level_m: Optional[float] # Maximum level limit (meters)
hard_max_power_kw: Optional[float] # Maximum power limit (kW)
max_speed_change_hz_per_min: float # Rate of change limit
```
#### Enforcement Process
```python
def enforce_setpoint(station_id: str, pump_id: str, setpoint: float) -> Tuple[float, List[str]]:
"""
Enforce safety limits on setpoint.
Returns:
Tuple of (enforced_setpoint, violations)
- enforced_setpoint: Safe setpoint (clamped if necessary)
- violations: List of safety violations (for logging/alerting)
"""
# 1. Check emergency stop first (highest priority)
if emergency_stop_active:
return (0.0, ["EMERGENCY_STOP_ACTIVE"])
# 2. Enforce hard speed limits
if setpoint < hard_min_speed_hz:
enforced_setpoint = hard_min_speed_hz
violations.append("BELOW_MIN_SPEED")
elif setpoint > hard_max_speed_hz:
enforced_setpoint = hard_max_speed_hz
violations.append("ABOVE_MAX_SPEED")
# 3. Enforce rate of change limits
rate_violation = check_rate_of_change(previous_setpoint, enforced_setpoint)
if rate_violation:
enforced_setpoint = limit_rate_of_change(previous_setpoint, enforced_setpoint)
violations.append("RATE_OF_CHANGE_VIOLATION")
# 4. Return safe setpoint
return (enforced_setpoint, violations)
```
### 2. Emergency Stop Manager (`src/core/emergency_stop.py`)
#### Purpose
Provides manual override capability for emergency situations with highest priority override of all other controls.
#### Emergency Stop Levels
1. **Station-Level Emergency Stop**:
- Stops all pumps in a station
- Activated by station operators
- Requires manual reset
2. **Pump-Level Emergency Stop**:
- Stops individual pumps
- Activated for specific equipment issues
- Individual reset capability
#### Emergency Stop Features
- **Immediate Action**: Setpoints forced to 0 Hz immediately
- **Audit Logging**: All emergency operations logged
- **Manual Reset**: Requires explicit operator action to clear
- **Status Monitoring**: Real-time emergency stop status
- **Integration**: Seamless integration with safety framework
#### Emergency Stop API
```python
class EmergencyStopManager:
def activate_emergency_stop(self, station_id: str, pump_id: Optional[str] = None):
"""Activate emergency stop for station or specific pump."""
def clear_emergency_stop(self, station_id: str, pump_id: Optional[str] = None):
"""Clear emergency stop condition."""
def is_emergency_stop_active(self, station_id: str, pump_id: Optional[str] = None) -> bool:
"""Check if emergency stop is active."""
```
### 3. Database Watchdog (`src/monitoring/watchdog.py`)
#### Purpose
Ensures database connectivity and activates failsafe mode if updates stop, preventing stale or unsafe setpoints.
#### Watchdog Features
- **Periodic Health Checks**: Continuous database connectivity monitoring
- **Failsafe Activation**: Automatic activation on connectivity loss
- **Graceful Degradation**: Safe fallback to default setpoints
- **Alert Generation**: Immediate notification on watchdog activation
- **Auto-Recovery**: Automatic recovery when connectivity restored
#### Watchdog Configuration
```python
class DatabaseWatchdog:
def __init__(self, db_client, alert_manager, timeout_seconds: int):
"""
Args:
timeout_seconds: Time without updates before failsafe activation
"""
```
### 4. Rate of Change Limiting
#### Purpose
Prevents sudden speed changes that could damage pumps or cause operational issues.
#### Implementation
```python
def check_rate_of_change(self, previous_setpoint: float, new_setpoint: float) -> bool:
"""Check if rate of change exceeds limits."""
change_per_minute = abs(new_setpoint - previous_setpoint) * 60
return change_per_minute > self.max_speed_change_hz_per_min
def limit_rate_of_change(self, previous_setpoint: float, new_setpoint: float) -> float:
"""Limit setpoint change to safe rate."""
max_change = self.max_speed_change_hz_per_min / 60 # Convert to per-second
if new_setpoint > previous_setpoint:
return min(new_setpoint, previous_setpoint + max_change)
else:
return max(new_setpoint, previous_setpoint - max_change)
```
## Safety Configuration
### Database Schema for Safety Limits
```sql

```python
# tests/unit/test_safety_framework.py
import pytest
from src.core.safety import SafetyFramework
class TestSafetyFramework:
def test_safety_limits_enforcement(self):

from src.core.optimization_manager import OptimizationManager
class TestDatabaseIntegration:
def test_optimization_plan_loading(self):

assert success == True
def test_safety_limits_persistence(self):
"""Test safety limits persistence and retrieval"""
