| 1 | """Regression tests for the musehub.js cleanup (issue #586). |
| 2 | |
| 3 | Verifies that displaced client-side rendering code has been removed from |
| 4 | musehub.js and all Jinja2 templates after the complete HTMX/SSR migration. |
| 5 | |
| 6 | Covers: |
| 7 | - test_musehub_js_does_not_contain_render_rows — renderRows not in musehub.js |
| 8 | - test_musehub_js_does_not_contain_build_bulk_toolbar — buildBulkToolbar not in musehub.js |
| 9 | - test_musehub_js_does_not_contain_render_filter_sidebar — renderFilterSidebar not in musehub.js |
| 10 | - test_musehub_js_file_size_under_target — file < 20 KB after cleanup |
| 11 | - test_explore_base_html_deleted — explore_base.html has been removed |
| 12 | - test_all_template_page_script_blocks_empty_or_minimal — no legacy data-fetching |
| 13 | patterns survive in any page template |
