| 1 | """Tests for the semver classifier (muse.core.semver_classifier). |
| 2 | |
| 3 | Coverage |
| 4 | -------- |
| 5 | StabilityManifest |
| 6 | - empty() returns a manifest with all frozensets empty. |
| 7 | - load() returns empty manifest when no stability.toml exists. |
| 8 | - load() parses [stable], [unstable], [experimental], [invisible] sections. |
| 9 | - stability_for() returns "stable" / "experimental" / "unstable" correctly. |
| 10 | - stability_for() defaults to "unstable" for undeclared symbols. |
| 11 | - stability_for() matches fnmatch glob patterns. |
| 12 | - is_invisible() matches repo-specific invisible patterns. |
| 13 | - is_invisible() returns False when no patterns match. |
| 14 | |
| 15 | _UNIVERSAL_INVISIBLE_PATTERNS |
| 16 | - LICENSE, *.md, *.txt match. |
| 17 | - docs/**, tests/** directories match. |
| 18 | - test_*.py, conftest.py match. |
| 19 | - *.lock, *.pyc match. |
| 20 | - Source .py files do NOT match. |
| 21 | - Binary files (*.png, *.mp3) do NOT match (not in universal patterns). |
| 22 | |
| 23 | ChangeClassification |
| 24 | - All fields stored as-is (frozen dataclass). |
| 25 | |
| 26 | SemVerClassification |
| 27 | - breaking_addresses returns sorted address list. |
| 28 | - all_classifications returns flat list of all four groups. |
| 29 | |
| 30 | classify_delta — core bump matrix |
| 31 | - Empty delta → bump="none", confidence=1.0. |
| 32 | - Insert public unstable → bump="patch". |
| 33 | - Insert public stable → bump="minor". |
| 34 | - Delete public unstable → bump="minor" (breaking on unstable surface). |
| 35 | - Delete public stable → bump="major". |
| 36 | - Replace with implementation change → bump="patch". |
| 37 | - Replace with signature change, stable → bump="major". |
| 38 | - Replace with signature change, unstable → bump="minor". |
| 39 | - Replace with rename, stable → bump="major". |
| 40 | - Replace with unrecognised summary → bump="minor" (unstable) with confidence<1.0. |
| 41 | - Multiple ops → highest bump wins. |
| 42 | |
| 43 | classify_delta — invisible gates |
| 44 | - Op on LICENSE file → invisible, bump="none". |
| 45 | - Op on *.md file → invisible, bump="none". |
| 46 | - Op on docs/** path → invisible, bump="none". |
| 47 | - Op on tests/** path → invisible, bump="none". |
| 48 | - Op on test_*.py file → invisible, bump="none". |
| 49 | - Op on *.pyc file → invisible, bump="none". |
| 50 | - PatchOp on invisible file → invisible, bump="none". |
| 51 | |
| 52 | classify_delta — private symbol gate |
| 53 | - Insert on underscore-prefixed symbol → invisible, bump="none". |
| 54 | - Delete on underscore-prefixed symbol → invisible, bump="none". |
| 55 | - Replace on underscore-prefixed symbol → invisible, bump="none". |
| 56 | |
| 57 | classify_delta — experimental surface |
| 58 | - Delete public experimental → bump="patch". |
| 59 | - Insert public experimental → bump="patch". |
| 60 | - Signature change experimental → bump="patch". |
| 61 | |
| 62 | classify_delta — PatchOp recursion |
| 63 | - PatchOp on non-invisible file with child insert → classifies children. |
| 64 | - PatchOp on invisible file → entire op is invisible. |
| 65 | - PatchOp with no child_ops → implementation change (confidence=0.7). |
| 66 | |
| 67 | classify_delta — MoveOp and MutateOp |
| 68 | - MoveOp on public exported symbol → implementation change. |
| 69 | - MutateOp on public exported symbol → implementation change. |
| 70 | - MoveOp on private symbol → invisible. |
| 71 | |
| 72 | classify_delta — DirectoryRenameOp |
| 73 | - Rename in code domain → breaking (confidence=0.5). |
| 74 | - Rename in non-code domain → invisible. |
| 75 | - Rename of invisible directory → invisible. |
| 76 | |
| 77 | ConflictRecord |
| 78 | - Default conflict_type is "file_level". |
| 79 | - All fields settable. |
| 80 | - addresses default factory is independent across instances. |
| 81 | |
| 82 | SemVerBump literals |
| 83 | - All four valid values are plain strings. |
