Python unit testing in emacs org mode
Using emacs org and babel1, I want to quickly note ideas in python. Now usually I start scripting up to a certain level of complexity / exhaustion which inevitably leads me to setup a complete python project folder in order to get proper unit testing.
Following setup allows me to stay in org mode and unit test. All together.
(defun ndk/org-babel-evaluate-test-block-from-code-block ()
(interactive)
(save-excursion
(org-babel-goto-named-src-block "python_code")
(org-babel-tangle '(4))
(org-babel-goto-named-src-block "pytest_python_code")
(org-babel-execute-src-block)))
(define-key evil-normal-state-map (kbd ", SPC") #'ndk/org-babel-evaluate-test-block-from-code-block)
Evaluating the upper elisp code block binds itself to , SPC .
Now hitting , SPC in block python_code, exports it and subsequently runs the unit test from block pytest_python_code
All while I’m staying in the code, at the same cursor position. No need to jump between code blocks. Beautiful quietness.
