One trick I use, especially when refactoring, is to use an interactive
rebase to test each commit in isolation, like:

  GIT_EDITOR='sed -i "/^pick .*/aexec make -j8 test"' git rebase -i

After picking each commit, that will run the tests on each one[1]. If it
fails, the rebase will pause. You can fix any problems, test to your
satisfaction, "commit --amend", and then "rebase --continue" to keep
going.

    often just compile-test at first, and then do a final "make test"
    pass when I think everything is right.
