# LAMMPS does have a test suite, but we do not use it, because it seems too
# fiddly to get it running properly.
#
# 1. Running the command listed in LAMMPS’ Jenkins tests [2] fails with a
# strange error:
#
# $ python run_tests.py tests/test_commands.py tests/test_examples.py
# Loading tests from tests/test_commands.py...
# Traceback (most recent call last):
# File "run_tests.py", line 81, in <module>
# tests += load_tests(f)
# File "run_tests.py", line 22, in load_tests
# for testname in list(tc):
# TypeError: 'Test' object is not iterable
#
# Looking in run_tests.py, this sure looks like a bug (it’s expecting a
# list of Tests, I think, but getting a single Test). But it works in
# Jenkins. Who knows.
#
# 2. The files test/test_*.py say that the tests can be run with
# “nosetests”, which they can, after setting several environment
# variables. But some of the tests fail for me. I didn’t diagnose.
#
# Instead, we simply run some of the example problems in a loop and see if
# they exit with return code zero. We don’t check output.
#
# Note that a lot of the other examples crash. I haven’t diagnosed or figured
# out if we care.
#
# We are open to patches if anyone knows how to fix this situation reliably.
