Add unit tests for validation

**Description**
Currently components lacks proper import support.

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

**Priority**: Low/Medium

Start by locating the validation unit tests and the component import code; the issue does not name files or existing entry points. Determine how configurable imports and sensible defaults should behave, then add tests that cover the intended validation and import cases.
