I use make for step 3. It seems natural after using it in step 2. Eg

cd test
make lisp/vc/ediff-ptch-tests.log

(till yesterday, it used to work without ".log" as well - see emacs-devel)

The test file names are completable using whatever your shell uses for
file name completion (eg alt-/ in bash). In emacs-25 they are completable
with bash TAB completion (from bash Makefile completion), which was nicer.

So personally I'm not sure I see the need to add an autoloaded ert
command to do this.
