The magic command can be unit tested with:

Create a configurable given a config config.

configConfig

If this is empty, default values are used. If config is a Config instance, it will be used to configure the instance.

parentConfigurable instance, optional

The parent Configurable instance of this object.

Subclasses of Configurable must call the __init__() method of Configurable before doing anything else and using super():

class MyConfigurable(Configurable):
    def __init__(self, config=None):
        super(MyConfigurable, self).__init__(config=config)
        # Then any other code you need to finish initialization.

This ensures that instances will be configured properly.
