I have written a few simple tests, when I run them on the buffer inside emacs everything passes.

However, when I run them in batch mode as shown below, it fails. What can explain this?

emacs -batch -l ert -l mytests.el -f ert-run-tests-batch-and-exit

Here's the output from one of the failing tests:

Test pp-test-docker-container-names backtrace:

Any ideas ?

(void-function loop)

loop is not available, which comes from cl.el. In your code/tests, you should load this library before using loop. When you launch Emacs interactively with your own init.el, it is usually already loaded since it is a common library used by many other packages.

  • Great that makes sense i have 1 test passing now the other is likely a similar issue, I know what to look forward i had assumed it would have been the same environment. – Oly Oct 29 '16 at 17:52
