docs: expand cache plan with all seven testing tiers and do…
Sonnet 4.6
131 days ago
| 1 | """Tests for ``muse code index`` (status / rebuild / purge). |
| 2 | |
| 3 | Coverage layers |
| 4 | --------------- |
| 5 | Unit |
| 6 | _build_symbol_history — empty repo, single commit with ops, manifest |
| 7 | cache (blob fetched once per obj_id), missing |
| 8 | manifest logged+skipped, no-op commits skipped, |
| 9 | SymbolCache consulted before read_object, |
| 10 | SymbolCache populated on miss. |
| 11 | _build_hash_occurrence — HEAD present, no HEAD (graceful empty), missing |
| 12 | manifest logged+empty, imports excluded, trivial |
| 13 | (size-1) entries excluded. |
| 14 | index_info — present, absent, corrupt states; entries is int. |
| 15 | purge_index — deletes existing file, returns False when absent, |
| 16 | raises ValueError for unknown name. |
| 17 | |
| 18 | Integration (live repo, CliRunner) |
| 19 | status: exit-0, JSON keys + types, absent text, present text. |
| 20 | rebuild: exit-0, JSON schema, all counts, text output. |
| 21 | rebuild --dry-run: no files written, JSON dry_run=true, counts correct. |
| 22 | rebuild --index symbol_history: only that index rebuilt. |
| 23 | rebuild --index hash_occurrence: only that index rebuilt. |
| 24 | purge: exit-0, JSON schema, present deleted, absent skipped. |
| 25 | purge --index <name>: only named index deleted. |
| 26 | Invalid --index rejected by argparse (exit non-zero). |
| 27 | Missing repo exits non-zero. |
| 28 | |
| 29 | E2E (real symbol changes across commits) |
| 30 | After rebuild, status shows both indexes as present with non-zero entries. |
| 31 | symbol_history entries reflect commit history (insert recorded). |
| 32 | hash_occurrence clusters > 0 when duplicate bodies exist. |
| 33 | Rebuild is idempotent: two consecutive rebuilds yield identical JSON. |
| 34 | Dry-run counts match a subsequent real rebuild. |
| 35 | Purge then status shows absent; rebuild restores present. |
| 36 | Purge --index only removes targeted index. |
| 37 | |
| 38 | Stress |
| 39 | 50-commit repo: rebuild completes, all symbol_history addresses > 0. |
| 40 | Manifest cache: blob fetched at most once per unique obj_id during rebuild. |
| 41 | Large flat file (200 functions): hash_occurrence correct after rebuild. |
