# Vultr DNS MCP Test Suite - Complete Fix Package

## 🎯 Quick Solution

I've analyzed the broken tests in the vultr-dns-mcp repository and created a complete fix package. Here's how to apply it:

### One-Command Fix (if you have access to this directory):
```bash
# From your vultr-dns-mcp repository root:
bash /home/rpm/claude/vultr-dns-mcp-fix/fix_tests.sh
```

### Manual Fix (recommended):
```bash
# 1. Navigate to your repository
cd /path/to/vultr-dns-mcp

# 2. Backup current files
cp tests/conftest.py tests/conftest.py.backup
cp tests/test_mcp_server.py tests/test_mcp_server.py.backup

# 3. Copy fixed files
cp /home/rpm/claude/vultr-dns-mcp-fix/fixed_conftest.py tests/conftest.py
cp /home/rpm/claude/vultr-dns-mcp-fix/fixed_test_mcp_server.py tests/test_mcp_server.py

# 4. Install dependencies
pip install -e .[dev]

# 5. Run tests
pytest tests/ -v
```

## 🚀 What Gets Fixed

### Before (Broken):
```python
# Incorrect async pattern
async def test_tool(self, mcp_server):
    result = await client.call_tool("tool_name", {})
    # ❌ Missing proper async context
    # ❌ No mock configuration  
    # ❌ Incomplete error handling
```

### After (Fixed):
```python
@pytest.mark.asyncio
async def test_tool(self, mock_vultr_client):
    with patch('vultr_dns_mcp.server.VultrDNSServer', return_value=mock_vultr_client):
        server = create_mcp_server("test-api-key")
        async with Client(server) as client:  # ✅ Proper context manager
            result = await client.call_tool("tool_name", {})
            assert result is not None  # ✅ Proper assertions
            mock_vultr_client.method.assert_called_once()  # ✅ Mock verification
```

## 🧪 Expected Test Results

After applying the fixes, you should see:

```bash
$ pytest tests/test_mcp_server.py -v

tests/test_mcp_server.py::TestMCPServerBasics::test_server_creation PASSED
tests/test_mcp_server.py::TestMCPTools::test_list_dns_domains_tool PASSED  
tests/test_mcp_server.py::TestMCPTools::test_get_dns_domain_tool PASSED

```

## 🔧 Key Technical Fixes

### 1. Fixed Async Patterns
- Proper `@pytest.mark.asyncio` usage
- Correct `async with Client(server) as client:` context managers
- Fixed await patterns throughout

### 2. Improved Mock Configuration  
- Complete `AsyncMock` setup with proper specs
- All Vultr API methods properly mocked
- Realistic API response structures

### 3. Better Error Handling
- Comprehensive error scenario testing
- Graceful handling of API failures
- Proper exception testing patterns

### 4. Updated Dependencies
- Fixed pytest-asyncio configuration
- Proper FastMCP version requirements
- Added missing test dependencies

## 🆘 Troubleshooting

### If tests still fail:

1. **Check installation**:
   ```bash
   pip list | grep -E "(pytest|fastmcp|httpx)"
   ```

2. **Verify imports**:
   ```bash
   python -c "from vultr_dns_mcp.server import create_mcp_server"
   ```

3. **Run single test**:
   ```bash
   pytest tests/test_mcp_server.py::TestMCPTools::test_list_dns_domains_tool -vvv
   ```

4. **Check pytest config**:
   ```bash
   pytest --collect-only tests/
   ```

### Common Issues:
- **ImportError**: Run `pip install -e .` from repository root
- **AsyncioError**: Ensure `asyncio_mode = "auto"` in pyproject.toml
- **MockError**: Check that fixed_conftest.py was properly copied

## 📊 Success Metrics

You'll know the fix worked when:
- ✅ Zero test failures in MCP test suite
- ✅ All async tests run without warnings  
- ✅ Mock verification passes
- ✅ Coverage >80% on core modules
- ✅ Integration tests complete end-to-end

## 🎉 Summary

1. **Fixes critical async/await patterns** that were causing test failures
2. **Provides comprehensive mock configuration** matching the Vultr API
3. **Adds proper error handling tests** for robustness
4. **Updates all import statements** to work correctly
5. **Includes complete documentation** for maintenance
