1 """Comprehensive hardening tests for ``muse push``.
2
3 Covers all changes introduced in the push command review:
4
5 Unit
6 ----
7 - Parser flags: --dry-run, --workers, --format/--json
8 - Dead-code removal: _current_branch absent
9 - _all_known_have_anchors: symlink skipping, binary-file safety, missing dir
10 - _upload_presigned: retry on 5xx/429, non-retriable 4xx propagated immediately
11 - _upload_chunk: progress goes to stderr, not stdout
12 - _PushJson TypedDict keys complete
13
14 Integration (with mocked transport)
15 ------------------------------------
16 - Error messages routed to stderr, stdout clean on errors
17 - remote not configured → stderr
18 - branch has no commits → stderr
19 - push rejected (result.ok=False) → stderr
20 - up_to_date JSON schema complete
21 - pushed JSON schema complete
22 - dry_run JSON schema complete
23 - deleted JSON schema complete
24 - --dry-run: no transport calls, correct counts
25 - --workers accepted without error
26 - --set-upstream records tracking ref
27 - 409/401/404/other TransportError → stderr + exit 1
28
29 End-to-end (local:// transport)
30 ---------------------------------
31 - Fresh push succeeds
32 - Second push (up_to_date) exits 0
33 - --dry-run shows would-push info without writing
34 - --format json produces valid JSON
35 - --force bypasses fast-forward check
36
37 Security
38 --------
39 - remote name sanitized in all error messages
40 - branch name sanitized in delete output
41 - del_branch sanitized in already-gone path
42 - _all_known_have_anchors: planted symlink skipped
43 - _all_known_have_anchors: binary file skipped
44 - invalid --format exits 1 to stderr
45 - progress prints from _upload_chunk go to stderr
46
47 Stress
48 ------
49 - _push_objects_parallel with 1000 objects (mocked transport)
50 - _upload_presigned retries exhaust then raise
51 - concurrent push runs to isolated repos
