e6786943 feat: upgrade to Python 3.14, drop from __future__ import annotations Gabriel Cardona <cgcardona@gmail.com> 1d ago
1 """Tests for the code domain plugin.
2
3 Coverage
4 --------
5 Unit
6 - :mod:`muse.plugins.code.ast_parser`: symbol extraction, content IDs,
7 rename detection hashes, import handling.
8 - :mod:`muse.plugins.code.symbol_diff`: diff_symbol_trees golden cases,
9 cross-file move annotation.
10
11 Protocol conformance
12 - ``CodePlugin`` satisfies ``MuseDomainPlugin`` and ``StructuredMergePlugin``.
13
14 Snapshot
15 - Path form: walks all files, raw-bytes hash, honours .museignore.
16 - Manifest form: returned as-is.
17 - Stability: two calls on the same directory produce identical results.
18
19 Diff
20 - File-level (no repo_root): added / removed / modified.
21 - Semantic (with repo_root via object store): symbol-level PatchOps,
22 rename detection, formatting-only suppression.
23
24 Golden diff cases
25 - Add a new function → InsertOp inside PatchOp.
26 - Remove a function → DeleteOp inside PatchOp.
27 - Rename a function → ReplaceOp with "renamed to" in new_summary.
28 - Change function body → ReplaceOp with "implementation changed".
29 - Change function signature → ReplaceOp with "signature changed".
30 - Add a new file → InsertOp (or PatchOp with all-insert child ops).
31 - Remove a file → DeleteOp (or PatchOp with all-delete child ops).
32 - Reformat only → ReplaceOp with "reformatted" in new_summary.
33
34 Merge
35 - Different symbols in same file → auto-merge (no conflicts).
36 - Same symbol modified by both → symbol-level conflict address.
37 - Disjoint files → auto-merge.
38 - File-level three-way merge correctness.
39
40 Schema
41 - Valid DomainSchema with five dimensions.
42 - merge_mode == "three_way".
43 - schema_version == 1.
44
45 Drift
46 - No drift: committed equals live.
47 - Has drift: file added / modified / removed.
48
49 Plugin registry
50 - "code" is in the registered domain list.
