@claude-flow/testing

Comprehensive testing framework for V3 Claude-Flow modules. Implements London School TDD patterns with behavior verification, shared fixtures, and mock services.

Based on ADR-008 (Vitest over Jest).

Installation

npm install @claude-flow/testing vitest --save-dev

Quick Start

import {
  setupV3Tests,
  createMockApplication,
  agentConfigs,
  swarmConfigs,
  waitFor,
} from '@claude-flow/testing';

// Configure test environment
setupV3Tests();

describe('MyModule', () => {
  const app = createMockApplication();

  beforeEach(() => {
    // Mocks are automatically reset
  });

  it('should spawn an agent', async () => {
    const result = await app.agentLifecycle.spawn(agentConfigs.queenCoordinator);

    expect(result.success).toBe(true);
    expect(result.agent.type).toBe('queen-coordinator');
  });
});

expect(app.taskManager.create).toHaveBeenCalled();

// Access tracked state
expect(app.eventBus.publishedEvents).toHaveLength(1);
expect(app.taskManager.tasks.size).toBe(1);

Mock Services

MockAgentDB

import { MockAgentDB } from '@claude-flow/testing';

const db = new MockAgentDB();

// Insert vectors
await db.insert('vec-1', embedding, { type: 'pattern' });

// Search
const results = await db.search(queryEmbedding, 10, 0.7);

// Verify calls
expect(db.insert).toHaveBeenCalledWith('vec-1', expect.any(Array), expect.any(Object));

MockSwarmCoordinator

import { MockSwarmCoordinator } from '@claude-flow/testing';

const coordinator = new MockSwarmCoordinator();

await coordinator.initialize({ topology: 'hierarchical-mesh' });
await coordinator.addAgent({ type: 'coder', name: 'Coder-1' });
const result = await coordinator.coordinate({ id: 'task-1', type: 'coding', payload: {} });

expect(coordinator.getState().agentCount).toBe(1);
expect(result.success).toBe(true);

MockMCPClient

import { MockMCPClient, createStandardMockMCPClient } from '@claude-flow/testing';

// Standard client with common tools
const client = createStandardMockMCPClient();
await client.connect();

// Custom tool handlers
client.setToolHandler('swarm_init', async (params) => ({
  content: [{ type: 'text', text: JSON.stringify({ swarmId: 'test' }) }],
}));

const result = await client.callTool('swarm_init', { topology: 'mesh' });

// Verify request history
expect(client.getRequestHistory()).toHaveLength(1);
expect(client.getLastRequest()?.method).toBe('tools/call');

Assertions

Standard Assertions

import {
  assertEventPublished,
  assertEventOrder,
  assertMocksCalledInOrder,
  assertV3PerformanceTargets,
  assertValidStateTransition,
  assertNoSensitiveData,
} from '@claude-flow/testing';

// Event assertions
assertEventPublished(mockEventBus, 'UserCreated', { userId: '123' });
assertEventOrder(mockEventBus.publish, ['UserCreated', 'EmailSent']);

// Mock order
assertMocksCalledInOrder([mockValidate, mockSave, mockNotify]);

// Performance targets
assertV3PerformanceTargets({
  searchSpeedup: 160,
  flashAttentionSpeedup: 3.5,
  memoryReduction: 0.55,
});

// State transitions
assertValidStateTransition('pending', 'running', {
  pending: ['running', 'cancelled'],
  running: ['completed', 'failed'],
});

// Security
assertNoSensitiveData(mockLogger.logs, ['password', 'token', 'secret']);

Custom Vitest Matchers

import { registerCustomMatchers } from '@claude-flow/testing';

// Register in setup
registerCustomMatchers();

// Use in tests
expect(mockFn).toHaveBeenCalledWithPattern({ userId: expect.any(String) });
expect(event).toHaveEventType('UserCreated');
expect(metrics).toMeetV3PerformanceTargets();

Setup & Teardown

Global Test Setup

import { setupV3Tests, configureTestEnvironment } from '@claude-flow/testing';

// Simple setup
setupV3Tests();

// Custom configuration
configureTestEnvironment({
  resetMocks: true,
  fakeTimers: true,
  suppressConsole: ['log', 'warn'],
  env: {
    NODE_ENV: 'test',
    DEBUG: 'false',
  },
});

Test Context

import { createSetupContext, createTestScope } from '@claude-flow/testing';

// Setup context with cleanup
const ctx = createSetupContext();
ctx.addCleanup(() => server.close());
ctx.registerResource(database);
// ... run tests
await ctx.runCleanup();

// Isolated test scope
const scope = createTestScope();
scope.addMock(mockService);
await scope.run(async () => {
  // test code - mocks auto-cleared after
});

Performance Testing

import { createPerformanceTestHelper } from '@claude-flow/testing';

const perf = createPerformanceTestHelper();

perf.startMeasurement('search');
await search(query);
const duration = perf.endMeasurement('search');

// Get statistics
const stats = perf.getStats('search');
console.log(`Avg: ${stats.avg}ms, P95: ${stats.p95}ms`);

Performance Targets

The testing framework includes assertions for V3 performance targets:

Metric	Target
Search Speedup	150x - 12,500x
Flash Attention Speedup	2.49x - 7.47x
Memory Reduction	>= 50%
Startup Time	< 500ms
Response Time	< 100ms

import { assertV3PerformanceTargets, TEST_CONFIG } from '@claude-flow/testing';

// Assert targets
assertV3PerformanceTargets({
  searchSpeedup: 160,
  flashAttentionSpeedup: 3.5,
  memoryReduction: 0.55,
  startupTimeMs: 450,
  responseTimeMs: 80,
});

// Access constants
console.log(TEST_CONFIG.FLASH_ATTENTION_SPEEDUP_MIN); // 2.49
console.log(TEST_CONFIG.AGENTDB_SEARCH_IMPROVEMENT_MAX); // 12500

Best Practices

1. Use London School TDD

// Arrange mocks before acting
const mockRepo = createMock<UserRepository>();
mockRepo.findById.mockResolvedValue(user);

// Act
await service.processUser('123');

// Assert behavior (not implementation)
expect(mockRepo.findById).toHaveBeenCalledWith('123');
expect(mockNotifier.notify).toHaveBeenCalledBefore(mockRepo.save);

2. Use Fixtures Over Inline Data

// Good - use fixtures
const agent = agentConfigs.queenCoordinator;
const task = createSwarmTask('securityScan');

// Avoid - inline data
const agent = { type: 'queen-coordinator', name: 'Test', capabilities: [] };

3. Isolate Tests

// Use fresh mocks per test
beforeEach(() => {
  vi.clearAllMocks();
});

// Or use test scope
const scope = createTestScope();
await scope.run(async () => {
  // isolated test
});

4. Test Behavior, Not Implementation

// Good - behavior verification
expect(mockEventBus.publish).toHaveBeenCalledWith(
  expect.objectContaining({ type: 'UserCreated' })
);

// Avoid - implementation details
expect(service._internalQueue.length).toBe(1);
