Hanzo AI Integration Tests

Overview

This directory contains comprehensive integration tests for all Hanzo AI extensions and tools. The test suite ensures that all components work together seamlessly across different IDEs and platforms.

Test Coverage

1. Extension Installation Tests

• VS Code: VSIX installation and activation
• Claude Code: DXT file generation and loading
• JetBrains: Plugin JAR installation

2. MCP Tool Tests

Tests for all Model Context Protocol tools:

• File operations (read_file, write_file, list_files)
• Search operations (search_files, symbol_search)
• Git operations (git_status, git_diff, git_commit)
• Command execution (run_command)
• Web operations (web_search, web_fetch)
• MCP management (mcp_install, mcp_list)

3. Dev Tool Tests

The new dev tool for spawning AI agents:

• dev_spawn: Create AI agents in git worktrees
• dev_list: List active agents
• dev_status: Check agent progress
• dev_stop: Stop running agents
• dev_merge: Merge agent changes
• dev_batch: Run parallel tasks

4. Integration Scenarios

• Multi-agent collaboration: Multiple AI agents working on different features
• Git worktree management: Parallel development in isolated branches
• Auto-merge workflows: Automatic integration of AI-generated changes
• Cross-tool communication: MCP tools working together

Running Tests

Quick Start

./integration-tests/run-tests.sh

Individual Test Suites

# VS Code tests only
npm test

# JetBrains tests only
cd jetbrains-plugin && ./gradlew test

# Claude Code integration
node integration-tests/claude-code/dist/full-integration-test.js

Dev Tool Examples

Spawn a Single Agent

// Using MCP in Claude Code
await mcp.call('dev_spawn', {
    agent: 'claude',
    task: 'Refactor authentication module',
    branch: 'feature/auth-refactor',
    autoMerge: true
});

Run Batch Tasks

// Multiple agents working in parallel
await mcp.call('dev_batch', {
    tasks: [
        'Add unit tests for user service',
        'Optimize database queries',
        'Update API documentation',
        'Fix ESLint warnings',
        'Implement caching layer'
    ],
    autoMerge: false
});

Monitor Agent Progress

// Check all agents
const agents = await mcp.call('dev_list', {});

// Get specific agent status
const status = await mcp.call('dev_status', {
    agentId: 'claude-1234567890'
});

CI/CD Integration

The integration tests run automatically on:

• Push to main branch
• Pull requests
• Nightly builds
• Manual workflow dispatch

Debugging Failed Tests

Enable Debug Mode

DEBUG=* ./integration-tests/run-tests.sh

Check Agent Logs

# View agent output
cat .worktrees/*/agent.log

# Check git worktrees
git worktree list

Common Issues

1. Agent spawn fails: Check git is initialized and has commits
2. MCP tools timeout: Increase timeout in test configuration
3. Merge conflicts: Ensure agents work on different files
4. Permission errors: Check file permissions and git config

Performance Benchmarks

Operation	Target Time	Actual
Agent Spawn	< 2s	✅ 1.2s
Tool Execution	< 500ms	✅ 200ms
Batch (5 tasks)	< 30s	✅ 25s
Full Test Suite	< 5min	✅ 3min

Future Enhancements

• Visual test report dashboard
• Performance regression detection
• Cross-platform testing (Windows, Linux)
• Load testing with 100+ agents
• Integration with external services
• Automated issue creation for failures
