I cannot reproduce this, either on the master, emacs-30 or emacs-29
branch (on a GNU/Linux system with ext4 file system).  For one thing,
when I run the equivalent of `make lisp/calendar/todo-mode-tests' (I
build out-of-tree) I get:

steve [ ~/build/emacs-master/test ]$ make ~/src/emacs/emacs-master/test/lisp/calendar/todo-mode-tests
make: *** No rule to make target '/home/steve/src/emacs/emacs-master/test/lisp/calendar/todo-mode-tests'.  Stop.

But when I run `make
~/src/emacs/emacs-master/test/lisp/calendar/todo-mode-tests.log' all
tests are run and all pass (on all three emacs branches).

Indeed, and the test uses `todo-test--add-file', whose doc string says:
"This provides a noninteractive API for todo-add-file for use in
automatic testing."  So I'm mystified as to why you get the hang above
and the error below.  From backtrace of the latter it looks like
`todo-read-category' from todo-mode.el is being used instead of the
mocked version defined in `todo-test--add-file', but I don't see how
that could have happened.
