27-assertion TAP-style suite for lib-management.dep-fetcher v0.1.0:
- 4 internal-helper tests (id_to_path, gitea_slug_for incl. .git
exception)
- 6 JSON decoder tests (objects/arrays/nesting)
- 3 conflict-detection tests (synthetic two-parent fixture)
- 3 closure-walk tests (clean fixture, check_only mode)
- 3 case-B (clean) tests
- 4 case-C (dirty) tests
- 4 case-D (wrong-tag → silent checkout, post-state verification)
Cases A (missing+clone) and E (broken describe) need network or
contrived corruption; out of scope for slice 5 per architecture spec.
Fixture matrix:
conflict_a/ — static, no .git needed
clean_b/ — .git at v0.1.0 (clean)
dirty_c/ — .git at v0.1.0-1-g…-dirty
wrong_tag_d/ — .git with tags v0.1.0 + v0.2.0, HEAD at v0.1.0
fixtures/_setup.sh reconstructs the .git states (idempotent — restores
manifest.lib content after the case-D silent-checkout side-effect).
Required pre-step before each test session; the test-runner blocks
with a clear error if fixtures/_setup.stamp is missing.
.gitignore covers the .git subdirs and the stamp file — they are
local-machine state, rebuilt by _setup.sh from the source-tracked
manifest.lib seed files.
