Summary:

When running:

pytest

on its own, test_cli_parsing() fails. However, if one runs:

pytest -k cli_test_parsing

pytest -v

or anything command that has more than one element to the command line, those tests pass.

It seems to be related to this line in pyani_script.py:

# Catch requests for citation and version information
if sys.argv[1].startswith("-"):

Reproducible Steps:

Run pytest with no options.

Current Output:

IndexError: list index out of range

It is difficult to provide more complete information about the error as attempts to increase the verbosity eliminate the bug.

Expected Output:

Describe what you expect the output to be. It is also very useful to know the expected "correct" behavior on your systems.
