Add unit tests for parsers

**Feature request**
It would be great to have timeout for utils.

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

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

The title requests unit tests for parsers, while the body requests a utils timeout and an enable_timeout configuration option; no files, parser entry points, or test paths are named. First clarify which request is in scope, then locate the relevant parser or utils tests and verify the requested behavior, including the false default if the timeout change is confirmed.
