Add unit tests for types

**Description**
Currently parsers lacks proper export support.

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

**Priority**: Low/Medium

The issue names no files, tests, or entry points; begin by locating the parser and type-handling code and any existing unit-test setup. Clarify whether the intended done state is test coverage only or configurable exports with sensible defaults, then verify the chosen behavior with unit tests.
