Key Integration Points

1. SwarmMemoryManager

const memoryStore = new SwarmMemoryManager(dbPath);
await memoryStore.initialize();

// Store coordination data
await memoryStore.store('coordination/data', data, {
  partition: 'coordination',
  ttl: 86400
});

// Retrieve shared data
const data = await memoryStore.retrieve('coordination/data', {
  partition: 'coordination'
});

2. EventBus

const eventBus = EventBus.getInstance();
await eventBus.initialize();

// Subscribe to events
eventBus.on('test.event', handler);

// Emit events
await eventBus.emit('test.event', { data: 'test' });

3. FleetManager

const fleetManager = new FleetManager(memoryStore, eventBus);
await fleetManager.initialize();

// Spawn agents
const agentId = await fleetManager.spawnAgent({
  type: 'coder',
  capabilities: ['coding']
});

---

Testing Patterns

1. Multi-Agent Coordination

// 3-agent workflow
const researcher = await fleetManager.spawnAgent('researcher');
const coder = await fleetManager.spawnAgent('coder');
const tester = await fleetManager.spawnAgent('tester');

// Pass data through memory
await memoryStore.store('research-result', researchData);
const data = await memoryStore.retrieve('research-result');

2. Concurrent Database Access

// 10 agents writing simultaneously
await Promise.all(
  agentIds.map(agentId =>
    memoryStore.store(`agent/${agentId}/data`, data)
  )
);

3. Event-Driven Coordination

// Subscribe to workflow events
eventBus.on('stage.completed', async (event) => {
  await memoryStore.store('workflow/stage', event);
  await eventBus.emit('stage.next', { previous: event.stage });
});

---

Database Tracking

All test suites store their status in SwarmMemoryManager:

Suite Initialization

await memoryStore.store('tasks/INTEGRATION-SUITE-XXX/init', {
  status: 'initialized',
  timestamp: Date.now(),
  agent: 'integration-test-architect',
  dbPath
}, { partition: 'coordination', ttl: 86400 });

Suite Completion

await memoryStore.store('tasks/INTEGRATION-SUITE-XXX/status', {
  status: 'completed',
  timestamp: Date.now(),
  agent: 'integration-test-architect',
  suiteType: 'multi-agent-workflows',
  testsCreated: 45,
  filesCreated: ['tests/integration/...']
}, { partition: 'coordination', ttl: 86400 });

Updating Tests

1. Always use real components (no mocks for core systems)
2. Store test status in SwarmMemoryManager
3. Use appropriate partitions (coordination, agents)
4. Set TTL for temporary test data
5. Clean up resources in afterAll()
