#set_fixture_class(class_names = {}) ⇒ Object

Sets the model class for a fixture when the class name cannot be inferred from the fixture name.

Examples:

set_fixture_class some_fixture:        SomeModel,
                  'namespaced/fixture' => Another::Model

The keys must be the fixture names, that coincide with the short paths to the fixture files.
