Add unit tests for routes

**Description**
Currently store lacks proper caching support.

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

**Priority**: Low/Medium

Start by locating the store and route code referenced by the issue, then inspect how requests are currently handled and whether any caching exists. Define the configurable caching behavior and sensible defaults before adding unit tests for routes; done means the tests cover the new behavior and the suite passes.
