That's one approach I suppose, it leaves evidence of "I wrote a test first" and such. However, it also feels more like a "work log" than a "commit log"; I like to make my commits atomic (test + code at the same time), so that in theory, each individual commit will pass CI. If you separate them, you can't just revert one commit, you need multiple.
