Purpose

Unit tests for the phonenumber parser of the observer content script.

Approach

This is only a start, far from complete. For this unit I only invoked the parser on texts. It would probably be a good idea to also make a test that runs in puppeteer.

Open Questions and Pre-Merge TODOs

• Use github checklists. When solved, check the box and explain the answer.

Learning

Had to use jsdom because the parser uses document.createElement in some places.
