QA
API Pagination Test Helper
Choose the declared pagination style and known values, then export a reviewable QA matrix without inventing API-specific status codes.
How this tool works
Offset and page-number pagination derive positions from numeric inputs. Cursor pagination treats a server-issued token as opaque. The right expected result depends on ordering guarantees and concurrent changes.
The helper creates first, middle, final, empty, invalid, oversized, duplicate-boundary, skipped-boundary, and cursor lifecycle ideas. It does not execute an endpoint.
Examples
- Calculate a partial final page from total and size.
- Test negative offset without inventing a status code.
- Detect a repeated or missing next cursor scenario.
Common use cases
Required context
- Document a stable sort key and tie-breaker.
- Record item IDs at page boundaries.
- Decide whether total count is exact, estimated, or absent.
- For cursors, treat the token as opaque and define expiration behavior.
Failure case: Pagination QA
Invalid/failure example
Detect a repeated or missing next cursor scenario.
Expected: The helper creates first, middle, final, empty, invalid, oversized, duplicate-boundary, skipped-boundary, and cursor lifecycle ideas. It does not execute an endpoint.

FAQ
Does this tool send the pasted data or execute an API request?
No. Analysis runs in this browser tab. The tool does not call pasted URLs, resolve remote references, or submit the input to a DevPouch processing endpoint.
Does the helper know what my API should return?
It derives generic invariants and arithmetic where a total is supplied. Status codes, caps, cursor opacity, ordering, and invalid-input behavior remain API-specific.
Why test duplicate and skipped boundaries?
Items inserted, deleted, or reordered between adjacent requests can expose unstable sorting or unsuitable pagination semantics.
