Is your feature request related to a problem? Please describe

We need to make sure that we don't break working 010 templates.

Describe the solution you'd like

Run tests against all 010 templates, making sure we don't regress. Passing 010 templates from 010 Editor's official template repository should be added as unit tests - once they pass, they should never fail again.
