21 days ago
| 1 | """Stress tests for the generic query engine and code query DSL. |
| 2 | |
| 3 | Covers: |
| 4 | - walk_history on linear chains of 100+ commits. |
| 5 | - CommitEvaluator with correct 3-arg signature. |
| 6 | - format_matches output format. |
| 7 | - Code query DSL: all field types, all operators, AND/OR composition. |
| 8 | - Code query DSL: unknown field raises ValueError. |
| 9 | - Query against large history (200 commits). |
| 10 | - Branch-scoped queries. |
