## Test Patterns Used

### 1. FastMCP Tool Testing Pattern
```python
@pytest.mark.asyncio
async def test_tool_success(mock_pool_manager):
    """Test successful tool execution."""
    # Setup mocks
    mock_pool_manager.spawn_pool = AsyncMock(return_value="pool_123")

    # Create MCP server
    mcp = FastMCP("test-mcp")
    register_pool_tools(mcp, mock_pool_manager)

    # Call tool
    result = await mcp.call_tool("tool_name", {"param": "value"})

    # Assert
    assert len(result) > 0
    import json
    data = json.loads(result[0].text)
    assert data["status"] == "success"
```

### 2. CLI Command Testing Pattern
```python
@patch("mahavishnu.cli.MahavishnuApp")
def test_command_success(mock_app_class):
    """Test CLI command success."""
    # Setup mocks
    mock_app = MagicMock()
    mock_app_class.return_value = mock_app

    # Run command
    result = runner.invoke(app, ["command", "args"])

    # Assert
    assert result.exit_code == 0
    assert "expected output" in result.stdout
```

### 3. Async Testing Pattern
```python
@pytest.mark.asyncio
async def test_async_operation():
    """Test async operation."""
    mock_obj = AsyncMock()
    mock_obj.async_method = AsyncMock(return_value={"status": "success"})

    result = await mock_obj.async_method()
    assert result["status"] == "success"
```

### 4. Error Handling Pattern
```python
@pytest.mark.asyncio
async def test_error_handling():
    """Test error handling."""
    mock_obj = AsyncMock()
    mock_obj.method = AsyncMock(side_effect=Exception("Error message"))

    result = await call_tool()
    assert "error" in result.lower()
```
