Add unit tests for components

**Description**
Currently data lacks proper timeout support.

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

**Priority**: Low/Medium

No file, component, entry point, or test path is identified in the issue. Start by locating the components that handle data operations and existing unit tests, then confirm the expected timeout configuration and defaults; done means configurable timeout support is covered by unit tests.
