I definitely plan some sort of regexp capability for selecting subsets of the tests.   Did you have a different use case in mind?  E.g., some sort of assert that matches a regexp instead of a strict string?    Hopefully someone out there already has a Fortran regexp facility that is license compatible.  I’ve not looked into it that far yet.    I do not want to have an external run-time dependency on python.   There can be environments where that is problematic.   

Cheers,
