## Test Structure Template

```rust
#[cfg(test)]
mod tests {
    use super::*;
    use ggen_core::graph::*;

    #[test]
    fn test_node_creation() -> Result<()> {
        // Arrange
        let mut graph = Graph::new();
        let node_data = NodeData::new("test");

        // Act
        let node_id = graph.add_node(node_data)?;

        // Assert
        assert!(graph.contains_node(node_id));
        assert_eq!(graph.node_count(), 1);

        Ok(())
    }

    #[test]
    fn test_invalid_node_retrieval() {
        let graph = Graph::new();
        let result = graph.get_node(NodeId::from(999));

        assert!(result.is_err());
        assert!(matches!(result, Err(GraphError::NodeNotFound(_))));
    }
}
```
