| 1 | """Tests for muse/core/indices.py — optional local index layer. |
| 2 | |
| 3 | Coverage |
| 4 | -------- |
| 5 | SymbolHistoryEntry |
| 6 | - to_dict / from_dict round-trip. |
| 7 | - All six fields preserved. |
| 8 | |
| 9 | symbol_history index |
| 10 | - save_symbol_history writes a valid JSON file. |
| 11 | - load_symbol_history reads it back correctly. |
| 12 | - load returns empty dict when file absent. |
| 13 | - load returns empty dict on corrupt JSON. |
| 14 | - Sorting: entries dict is sorted by address. |
| 15 | - Multiple addresses, multiple events per address. |
| 16 | |
| 17 | hash_occurrence index |
| 18 | - save_hash_occurrence writes a valid JSON file. |
| 19 | - load_hash_occurrence reads it back correctly. |
| 20 | - load returns empty dict when file absent. |
| 21 | - load returns empty dict on corrupt JSON. |
| 22 | - Addresses within each hash entry are sorted. |
| 23 | |
| 24 | index_info |
| 25 | - Reports "absent" for missing indexes. |
| 26 | - Reports "present" + correct entry count for existing indexes. |
| 27 | - Reports "corrupt" for malformed JSON. |
| 28 | - Reports both indexes. |
| 29 | |
| 30 | Schema compliance |
| 31 | - schema_version == __version__. |
| 32 | - updated_at is present and is a non-empty string. |
| 33 | - index field matches the index name. |
