How do I eval the code when run its test in elisp with Emacs?

Question

I'm writing some small puzzles to learn Emacs Lisp.

However, my current workflow is way too tedious :

1. change the code
2. eval-region or eval-buffer code
3. change the test
4. eval-region or eval-buffer test code
5. Mx ert , then press enter to run tests

How do I setup Emacs or the tests, so I can just "run the test" and Emacs will eval all codes for me ?

Answer 1

You probably should not run your tests within your Emacs session anyway. Rather, run the tests in a fresh Emacs session:

$ emacs -Q -b -l my-source-file.el -l my-test-file.el -f ert-run-tests-batch-and-exit

You can run this from Mx compile .
