My app has search, filtering, or sorting, and I want tests proving they return the right things, because 'close enough' search results erode trust fast. Find every search, filter, and sort feature and write tests covering: 1. Correctness: a search for a known term returns the records it should and excludes the ones it shouldn't. Test exact matches, partial matches, and case behavior. 2. Empty and special input: blank searches, searches with only whitespace, and searches full of special characters (`%`, `_`, quotes, regex-ish input) return sane results instead of crashing or dumping the entire table. 3. Permission scoping: filtered and searched results only include records the requesting user is allowed to see. This is the critical one. A search that returns other users' private records is a data leak with a UI. 4. Filter combinations: multiple filters applied together narrow results correctly instead of one silently overriding another. 5. Sorting: results come back in the requested order, including with ties, and sorting doesn't drop records. 6. Interaction with pagination (if my app paginates): filtering plus pagination returns correct totals and no duplicates or gaps between pages. Seed the test database with a deliberate fixture set designed to expose mistakes: similar names, records belonging to different users, records differing only in the filtered field. When finished, run the suite and report which behaviors hold and which leak, drop, or scramble results.
