🧪 Add Comprehensive Async Testing Framework for VoltAgent

[codegen-sh]

🚀 Overview

This PR establishes a comprehensive async testing framework for the VoltAgent TypeScript AI Agent Framework, providing robust testing utilities and patterns specifically designed for asynchronous operations.

✨ Key Features

🔧 Testing Infrastructure

• Jest Configuration: Optimized for async testing with 30s timeout and custom matchers
• TypeScript Support: Full type safety with path mapping (@/ and @tests/)
• Custom Matchers: Extended Jest with async-specific matchers

🛠️ AsyncTestUtils Library

• delay() and delayedReject() - Controlled timing utilities
• waitFor() - Condition polling with timeout
• waitForSettlement() - Promise settlement tracking
• runConcurrently() - Concurrent operation execution and measurement
• retry() - Retry mechanism with exponential backoff
• createControllablePromise() - Manual promise control for testing
• measureExecutionTime() - Performance measurement utilities

🎯 Custom Jest Matchers

// Test promise resolution within timeout
await expect(asyncOperation()).toResolveWithin(1000);

// Test promise rejection within timeout  
await expect(failingOperation()).toRejectWithin(500);

// Test eventual value equality with polling
await expect(() => getAsyncValue()).toEventuallyEqual('expected', 5000);

🤖 Agent Framework

• Agent Class: Async processing, streaming, health checks, timeout handling
• AgentManager: Multi-agent coordination, concurrent processing, event system
• Error Recovery: Robust error handling and state management

📊 Test Coverage

Unit Tests

• ✅ Agent async operations (processing, streaming, health checks)
• ✅ AgentManager multi-agent coordination
• ✅ AsyncTestUtils utility functions
• ✅ Error handling and recovery scenarios
• ✅ State management and lifecycle

Integration Tests

• ✅ End-to-end async workflows
• ✅ Performance and load testing (50 agents, 1000 operations)
• ✅ Memory pressure scenarios
• ✅ Concurrent user request simulation
• ✅ Real-world AI agent pipeline simulation

Performance Benchmarks

• ✅ High concurrency handling (50+ agents)
• ✅ Load testing with concurrent operations
• ✅ Memory management validation
• ✅ Timeout and resilience testing

🚀 Getting Started

# Install dependencies
npm install

# Run all tests
npm test

# Run tests in watch mode
npm run test:watch

# Run with coverage
npm run test:coverage

# Run only async tests
npm run test:async

💡 Usage Examples

import { Agent, AgentManager } from 'voltagent';
import { AsyncTestUtils } from './tests/utils/async-test-utils';

// Basic agent usage
const agent = new Agent({ name: 'my-agent', timeout: 5000 });
await agent.initialize();
const response = await agent.processRequest('Hello, world!');

// Multi-agent coordination
const manager = new AgentManager();
await manager.createAgent({ name: 'agent-1' });
await manager.createAgent({ name: 'agent-2' });
const results = await manager.processAcrossAgents(['agent-1', 'agent-2'], 'batch request');

// Advanced async testing
const { results, duration, errors } = await AsyncTestUtils.runConcurrently([
  () => agent1.processRequest('test1'),
  () => agent2.processRequest('test2'),
  () => agent3.processRequest('test3')
]);

🎯 Benefits

• Async-First: Built specifically for asynchronous AI agent operations
• Comprehensive Testing: Covers unit, integration, and performance scenarios
• Developer Experience: Rich utilities and custom matchers for easier testing
• Production Ready: Robust error handling and resource management
• Scalable: Tested with high concurrency and load scenarios
• Type Safe: Full TypeScript support with proper type definitions

This framework provides a solid foundation for building and testing async AI agents with confidence! 🚀

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and explain its main purpose.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.
