Helpers for unit-testing Juju charms

Project Description

Latest Version Build Status Coverage Documentation Status

This package sports a collection of helpers for unit-testing Juju charms.

In particular, it extends systemfixtures by faking out hook tools processes (config-get, juju-log, etc), so authors have a complete suite of fakes for the typical “boundaries” of a Juju charm.

>>> def example_charm_logic():
...     return {
