We have ~1000 regression test snippets (pieces of music notation that describe and show one feature).

We haven’t found a fully automated way of testing this yet.

What we do is use ImageMagick’s `compare’ command with alpha channel colouring on png images between releases.

These images are presented on a web page, ordered by their difference. This makes it fairly easy to catch errors while allowing for development.

This page which shows the differences between 2.13.3 as compared to 2.13.0

For more test results, see http://lilypond.org/test
