How to set up bash completion

When using bash as your shell, pytest can use argcomplete (https://kislyuk.github.io/argcomplete/) for auto-completion. For this argcomplete needs to be installed and enabled.

Install argcomplete using:

sudo pip install 'argcomplete>=0.5.7'

For global activation of all argcomplete enabled python applications run:

sudo activate-global-python-argcomplete

For permanent (but not global) pytest activation, use:

register-python-argcomplete pytest >> ~/.bashrc

For one-time activation of argcomplete for pytest only, use:

eval "$(register-python-argcomplete pytest)"
