Not sure what you are asking about.  There's a test suite for
treesit.el in the tests directory.  If that is not what you want, we
had past discussions about specific C files that had problems with
tree-sitter (fixed since then), maybe you could use those files?

Fontification, indentation, and navigation by defun are the main
features supported by tree-sitter.  In some modes also Imenu.

All of the tree-sitter based modes are called SOMETHING-ts-mode, and
they are all called out in NEWS on the emacs-29 branch.  Does this
answer your question?
