"""
Module 4.3: NodesTable and EdgesTable Testing - Milestone 4

Tests NodesTable and EdgesTable types for node/edge-specific columnar operations.
These tables provide specialized views and operations on node and edge data.

Test Coverage:
NodesTable (62.5% pass rate, 20/32 methods):
- Basic table operations (head, tail, shape, filtering)
- Node-specific operations (node_ids, with_attributes)
- I/O operations (from_csv, to_csv, from_json, to_json, from_parquet, to_parquet)
- Grouping and sorting (group_by, sort_by, sort_values)
- Pandas integration (to_pandas)

EdgesTable (64.9% pass rate, 24/37 methods):
- Basic table operations (head, tail, shape, filtering)
- Edge-specific operations (edge_ids, sources, targets, as_tuples)
- Edge filtering (filter_by_sources, filter_by_targets)
- I/O operations (from_csv, to_csv, from_json, to_json, from_parquet, to_parquet)
- Grouping and sorting (group_by, sort_by, sort_values)
- Pandas integration (to_pandas)

Success Criteria: 90%+ pass rate, I/O operations work, edge/node patterns documented
