method
register
register(key, example_group_class)
public
Registers an example group class klass with the symbol type. For example:
Spec::Example::ExampleGroupFactory.register(:farm, FarmExampleGroup)
With that you can append a hash with :type => :farm to the describe method and it will load an instance of FarmExampleGroup.
describe Pig, :type => :farm do ...
If you don’t use the hash explicitly, describe will implicitly use an instance of FarmExampleGroup for any file loaded from the ./spec/farm directory.
