If a real person making commits uses their own account (just on that
machine), he or she can set up `user.name` and `user.email` settings in
the per-user Git configuration file with

  $ git config --global user.name  "My Name"
  $ git config --global user.email me@xxxxxxxxxxxx

If however one is doing commits from the "automatic test user" account,
then the `pre-commit` or `commit-msg` hook configured for that specific
repository for that automatic account would be run, which can detect
that the commit was not done with

  $ git commit --author="My Name <me@xxxxxxxxxxxx>"

The additional advantage is that you can examine committer data to
detect such cases of committing out of automatic account.

I hope that helps,
