Add unit tests for utils

**Feature request**
It would be great to have export for parsers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_export` with default `false`.

Start by locating the utils and parser entry points, then trace how configuration options are defined and read. Identify the existing unit-test location for these utilities before deciding where coverage belongs. Done means parser export is available when enable_export is true and remains disabled by default.
