argparse.ArgumentError: argument --log-level: conflicting option string: --log-level_

reason

Nameko and pytest have the same option --log-level for pytest_addoption, so pytest will raise argparse.ArgumentError.

  • Python 2.7.12
  • pytest 3.3.1
  • nameko 2.8.1

Downgrading pytest to a version lower than 3.3 indeed works.
