test_datetime.py

# See https://github.com/python/cpython/blob/3.9/Lib/test/datetimetester.py
#
# This script can be run in 3 different modes:
# 1. `python3 test_datetime.py --stdlib`: checks that the tests comply to
#    CPython's standard datetime library.
# 2. `python3 test_datetime.py`: runs the tests against datetime.py, using
#    CPython's standard unittest (which accepts filter options, such as
#    `-v TestTimeDelta -k tuple`, and provides more verbose output in case
#    of failure).
# 3. `micropython test_datetime.py`: runs the tests against datetime.py
#    using MicroPython's unittest library (which must be available).
#
# This script also accepts option `--reorder` which rewrites this file
# in-place by numbering tests in sequence.
