How to test git hooks

Since "testing" is a common use for a Git hook, my question is hard to search for.

I'm writing a fairly involved git post-receive hook and want to know what the best way to test it is. Currently my process is:

  • make changes to post-receive in a dummy "remote" repo
  • make a change to a dummy local repo
  • commit change in dummy local repo
  • push change to dummy remote repo

Is there any easier way to test this? Ideally it would look like:

  • make change(s) to post-receive in a dummy repo
  • issue "magic" command to test post-receive

Perhaps I can "reissue" a previous push or have the remote repo act as though it just received a push with a specific hash?

My approach is to dial the HEAD at the remote repo back one commit, and then push again:

ssh <repo> 'cd /<repo_path>; git update-ref refs/heads/master HEAD^' && git push origin master

For debugging you could also end your hook in something like this:

echo "No errors found."
exit 1

If you are happy with you hook you of course take out the last line again.
