Testing fontification, indentation, and buffer manipulation

[Daniele Nicolodi]

Hello,

I am hacking on beancount-mode (a mode to edit Beancount ledger files)
and I would like to write some automated tests to check the
functionality of the minor mode.  I found ERT, but it seems that it does
not offer any facility to easily test fontification, indentation, or
buffer manipulation in general.

Is there any facility that would help in writing such tests?

Thank you.

Cheers,
Dan
