Foundation Backport Testing Strategy
Executive Summary
This document defines the comprehensive testing strategy for backporting agent-aware capabilities into the existing Foundation infrastructure. The analysis reveals that Foundation has exceptional test coverage (90%+ of requirements) with enterprise-grade testing infrastructure, requiring only targeted enhancements for agent-specific functionality rather than rebuilding test infrastructure.
Current Test Infrastructure Assessment
Strengths of Existing Test Architecture ✅
- Comprehensive Component Coverage: All backport targets have thorough test coverage
- Sophisticated Test Infrastructure: Advanced helpers, isolation, and resource management
- Multiple Testing Levels: Unit, integration, property-based, stress, and security testing
- Concurrent Testing Excellence: Proper isolation and thread-safety verification
- Real-World Scenario Testing: Production-like usage patterns
- Performance Testing: Load testing with resource monitoring
- Property-Based Testing: Advanced generative testing with StreamData
Test Coverage Analysis by Component
Component | Current Coverage | Agent-Aware Gaps | Enhancement Required |
---|---|---|---|
ProcessRegistry | ✅ Excellent | Agent metadata, discovery | Medium |
CircuitBreaker | ✅ Excellent | Agent health integration | Low |
RateLimiter | ✅ Excellent | Agent capability throttling | Medium |
ConfigServer | ✅ Excellent | Agent-specific config | Low |
EventStore | ✅ Good | Agent correlation, subscriptions | Medium |
TelemetryService | ✅ Good | Agent metrics aggregation | Medium |
Coordination | ✅ Excellent | Agent-aware coordination | High |
Testing Gaps for Agent-Aware Features
1. Agent Lifecycle Integration Testing
Current State: Basic service lifecycle testing Required Enhancement: Agent-specific lifecycle management
New Test Requirements:
defmodule Foundation.Agent.LifecycleTest do
# Agent registration with rich metadata
# Agent health monitoring and state transitions
# Agent capability discovery and updates
# Agent resource requirement validation
# Agent coordination participation
end
2. Agent Metadata Validation Testing
Current State: Basic metadata support in ProcessRegistry Required Enhancement: Agent-specific metadata validation and querying
New Test Requirements:
defmodule Foundation.ProcessRegistry.AgentMetadataTest do
# Agent metadata schema validation
# Agent capability-based discovery
# Agent health status tracking
# Agent resource usage monitoring
# Agent coordination state management
end
3. Multi-Agent Coordination Testing
Current State: Basic coordination primitives testing Required Enhancement: Agent-aware coordination scenarios
New Test Requirements:
defmodule Foundation.Coordination.AgentAwareTest do
# Agent-aware consensus with health consideration
# Agent capability-based leader election
# Agent resource allocation coordination
# Agent coordination failure recovery
# Cross-agent communication patterns
end
4. Agent Resource Management Testing
Current State: No centralized resource management testing Required Enhancement: Comprehensive resource testing for agents
New Test Requirements:
defmodule Foundation.Infrastructure.ResourceManagerTest do
# Agent resource allocation and tracking
# Resource threshold monitoring and alerting
# Resource contention resolution
# Resource usage prediction and optimization
# Resource cleanup and recovery
end
