 If you use a test factory such as [FactoryGirl](https://github.com/thoughtbot/factory_girl), you can require your test factories and share the params. For example in FactoryGirl you can use the `attributes_for(:name_of_factory)` method.
 
+### Custom Headers
+
+If there are certain headers (such as auth token) that need to be present to
