26.0.50; Command to run tests with latest source |
Date: |
Sun, 02 Apr 2017 14:28:10 +0900 |
Severity: wishlist
I often while debugging follow this workflow:
1) Make some changes in one branch.
2) Compile Emacs.
3) Run one test file with:
M-& emacs -batch -l ert -l ? -f ert-run-tests-batch-and-exit RET
I never remember the exact command in 3), so i always first check the manual.
We have `ert-run-tests-interactively', but that command won't use
the just compiled sources: you need first to reload the new .elc.
I just wrote one command to do 1-3 above.
Interactively prompts for the file with the tests.
With a prefix argument, also prompts for the selector. Default to run
all the tests.
Do you think could be worth to have such a command in ert.el?

I still think it's a bit OOT to add something just to save typing:

Maybe you could define "ert-batch" as an alias for ert-run-tests-batch
(or ert-run-tests-batch-and-exit)? Then it really is very little typing.
Thanks, it sounds good idea. I will follow it and close the report.
