Is there a way to discover if Emacs is being run in batch and/or running
a test?
I have a package that uses "after-change-functions" and several other
"self-niling" hooks. If I have a bug in my package, the hook function
automatically gets removed, leaving the package in an inconsistent state
(because one hook may have gone but the others remain). So instead I use
"condition-case" to catch any errors and disable the entire package
(i.e. all of the hook functions) if an error occurs.
This works well, but unfortunately effectively swallows the backtrace.
Particularly annoying when I am running automated tests. So, I want to
write a macro like `condition-case-unless-debug' but which is "unless
running in batch or running ert". But I don't know how to find out if I
am in batch or running ert!

Maybe you want the variable 'noninteractive'?
(info "(elisp)batch mode")

I thought this article was very good on the topic of scripting with
Emacs: http://www.lunaryorn.com/2014/08/12/emacs-script-pitfalls.html
