-# GNU Make file for the automation of pytest for appendfilename
-#
-# While the test script is written for Python 3.9.2, it depends on
-# your installation of pytest (and in case of Linux, the authors of
-# your distribution) if pytest for Python 3 is invoked either by
-# pytest, or pytest-3.  In some distributions, pytest actually may
-# invoke pyest for legacy Python 2; the tests in test_date2name.py
-# however are incompatible to this.
-#
-# 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     # the pattern by pytest's manual
-pytest-3 -v test_appendfilename.py   # the alternative pattern (e.g., Debian 12)
