| 1 | """Tests for the MuseHub topics/tag browse API endpoints. |
| 2 | |
| 3 | Covers acceptance criteria: |
| 4 | - test_list_topics_empty — no public repos → empty topics list |
| 5 | - test_list_topics_aggregates_counts — counts reflect public repos only |
| 6 | - test_list_topics_excludes_private_repos — private repo tags are not counted |
| 7 | - test_list_topics_sorted_by_count_desc — most popular topic appears first |
| 8 | - test_repos_by_topic_empty — unknown tag → empty list (not 404) |
| 9 | - test_repos_by_topic_returns_tagged_repos — only repos with exact tag returned |
| 10 | - test_repos_by_topic_excludes_private — private repos are hidden |
| 11 | - test_repos_by_topic_sort_by_stars — stars sort returns most-starred first |
| 12 | - test_repos_by_topic_sort_by_updated — updated sort returns most-recently-committed first |
| 13 | - test_repos_by_topic_invalid_sort — invalid sort param returns 422 |
| 14 | - test_repos_by_topic_pagination — page 2 returns different repos |
| 15 | - test_set_topics_requires_auth — POST without MSign auth returns 401 |
| 16 | - test_set_topics_owner_only — non-owner gets 403 |
| 17 | - test_set_topics_replaces_list — new list replaces old list entirely |
| 18 | - test_set_topics_deduplicates — duplicate slugs are collapsed |
| 19 | - test_set_topics_invalid_slug — bad slug characters return 422 |
| 20 | - test_set_topics_too_many — more than 20 topics returns 422 |
| 21 | - test_set_topics_clears_list — empty body clears all topics |
| 22 | - test_set_topics_repo_not_found — unknown repo_id returns 404 |
