# Export the tangled files with C-c C-v t
#+PROPERTY: header-args :tangle yes
* Intent
The application =appendfilename= by Karl Voit /et al./ ([[https://github.com/novoid/appendfilename][source]])
allows the programmatic addition of user defined strings to one or
multiple already existing file names (e.g., add =travel= to file
=example.jpg= to yield =example_travel.jpg=). By the command =C-c
C-v t=, Emacs may use the present =.org= file to (re)generate a
tangled test script, file =test_appendfilename.py= for a
programmatic testing by [[https://docs.pytest.org/en/latest/][pytest]]. (Though =pytest= is not part of the
Python standard library, it may be obtained easily e.g., from [[https://pypi.org/project/pytest/][PyPi]].)
Optionally, the testing may be run by the equally tangled
=Makefile=.
* Deployment
On a computer with Python 3 only, the recommended call on the CLI to
run the tests is either one of the following instructions (you might
need to add the executable bit):
#+begin_src bash :tangle no
python pytest -v test_appendfilename.py
./Makefile
#+end_src
In case the computer you use equally includes an installation of
legacy Python 2 side-by-side to Python 3, you must explicitly call
for the later branch of the two. Depending on your OS, this
requires an adjustment of the command issued. In Linux Debian
12/bookworm, branch testing, for example,
#+begin_src bash :tangle no
python3 pytest-3 -v test_appendfilename.py
#+end_src
* Setup of Emacs
The edit of this =.org= file in Emacs and the subsequent export
(tangle) of the files are affected by Emacs' own parameters (e.g.,
the indentation in Python). It is recommended to access this file
with Emacs in a session started by =emacs -q test_generator.org &=
and to evaluate the following block by =C-c C-c=; this explicitly
adjusts a few basic settings, but does not permanently overwrite an
already existing personalized Emacs configuration.
Most of these instructions are elements of Hendrik Suenkler's
annotated Emacs configuration ([[https://www.suenkler.info/notes/emacs-config/][blog post]]) which are reused with his
permission.
#+begin_src emacs-lisp :tangle no
;; support these languages at all:
(org-babel-do-load-languages
'org-babel-load-languages
'((emacs-lisp . t)
(org . t)
(shell . t)
(python . t)))
;; enable syntax highlighting:
(setq org-src-fontify-natively t)
;; adjust indentations, set tabs as explicit 4 spaces:
(setq-default indent-tabs-mode nil)
(setq default-tab-width 4)
(setq custom-tab-width 4)
(setq-default python-indent-offset custom-tab-width)
(setq org-edit-src-content-indentation 0)
(setq org-src-tab-acts-natively t)
(setq org-src-preserve-indentation t)
;; some comfort functions Suenkler mentions:
(delete-selection-mode 1)
(defalias 'yes-or-no-p 'y-or-n-p)
(show-paren-mode 1)
(setq show-paren-style 'parenthesis)
(column-number-mode nil)
(setq org-src-fontify-natively t)
#+end_src
#+RESULTS:
: t
If the previous block was evaluated as .TRUE. (=t=), test script and
Makefile may be tangled right now by =C-c C-v t=. After closing
this =.org= file, deploy them as indicated earlier.
* Building the tests
** Building of the Makefile
The setup is for GNU Make 4.3 as provided e.g., by Linux Debian 12
(bookworm), branch testing. Note, the Makefile tangled is a mere
convenient moderator for =test_appendfilename.py=; the eventual
testing of appendfilename's action does not depend on this
Makefile.
#+BEGIN_SRC makefile :tangle Makefile
# GNU Make file for the automation of pytest for appendfilename.
#
# While the test script is written for Python 3.9.2, you might need to
# adjust the following instruction once in case your OS includes
# pytest for legacy Python 2 side by side to Python 3, or only hosts
# pytest for Python 3. The tests in script test_appendfilename.py are
# set up to work with pytest for Python 3; dependent on your
# installation, which may be named pytest-3, or (again) pytest.
#
# Put this file like test_appendfilename.py in the root folder of
# appendfilename fetched from PyPi or GitHub. Then run
#
# chmod +x *
# make ./Makefile
#
# to run the tests. If you want pytest to exit the test sequence
# right after the first test failing, use the -x flag to the
# instructions on the CLI in addition to the verbosity flag to (-v).
# pytest -v test_appendfilename.py # only pytest for Python 3 is present
pytest-3 -v test_appendfilename.py # pytest if Python 2 and Python 3 coexist
#+end_src
** Building a pytest.ini
This file defines markers to assign tests into groups. This allows to run
=pytest= on a subset rather than all tests (which is set up as the default).
E.g., in presence of =pytest.ini=, a call like
#+begin_src bash :tangle no
pytest-3 test_appendfilename.py -v -m "default"
#+end_src
constrains the tester's action to all tests labeled as "default" as about the
default position where the text string is added. At present, tests are
grouped as
+ default; appendfilename's default string insertions
+ prepend; corresponding to appendfilename's optional -p/--prepend flag, and
+ smart; corresponding to appendfilename's optional --smart-prepend flag
It is possible to run one, two, or all three groups in one run of pytest.
E.g., a simultaneous check of tests belonging to either default, or prepend
optional requires the instruction
#+begin_src bash :tangle no
pytest-3 test_appendfilename.py -m "default and prepend" -v
#+end_src
#+begin_src python :tangle pytest.ini
[pytest]
markers =
default: check the default insertion position of appendfile
prepend: check the prepend insertion position of appendfile
smart: check the smart-prepend insertion position of appendfile
