Add unit tests for routes

**Description**
Currently hooks lacks proper filtering support.

**Proposed solution**
Add configurable filtering with sensible defaults.

**Priority**: Low/Medium

Start by locating the hooks and route-handling code, then identify the existing unit-test entry point for routes. Clarify how configurable filtering and its sensible defaults should behave before adding coverage; done means the expected filtering cases and default behavior are tested.
