How to Test Search Functionality in Vibecoded Apps

Start with straightforward searches using exact terms that exist in your data and confirm results appear. Then test partial matches, misspellings, and case sensitivity. AI-generated search often only returns exact matches, missing results when users type slightly differently than the stored data. A search for 'javascript' should also find 'JavaScript' and 'JAVASCRIPT'.

Test edge cases: empty queries, single-character queries, very long queries, and queries with special characters like quotes, ampersands, and angle brackets. Many vibecoded search implementations crash or return errors on special characters because the input is not sanitized before being used in a database query or API call.

Search for a term that appears in multiple records and verify that the most relevant results appear first. AI-generated search usually implements basic LIKE or CONTAINS matching with no relevance ranking, so a partial match in a title and a full match in a footnote are treated equally. If relevance matters to your users, this is a key area to improve.

Test search results display: does each result show enough context for users to identify what they are looking for? Are search terms highlighted? What happens when there are hundreds of results — is there pagination or infinite scroll? Verify that clicking a search result takes you to the right place and that you can return to search results with the back button.

If your search supports filters (by date, category, status, etc.), test each filter individually and in combination. AI-generated filter logic often works for individual filters but breaks when multiple are combined — for example, filtering by both category AND date might return category OR date results instead.

Test search performance with a realistic amount of data. With 10 records search is always fast, but with 10,000 or 100,000 records, AI-generated search queries without proper indexes become noticeably slow. Time your searches and set a performance budget — search results should appear within 500 milliseconds for a good user experience.
