The publish/subscribe pattern is a messaging pattern that allows multiple consumers to subscribe and publish messages to other components without knowing the implementation details about those components. This lack of knowledge about the other components promotes loose coupling between the components and increases the maintainability of the application immensely. Subscribers to messages get notified when an event occurs related to the subscribed message. For long-running processes or AJAX requests, three messages are usually involved: one to invoke the process or request, another to indicate when the process or request completes, and a third to notify consumers of a failure.

The inject method takes a function with a list of the services you want injected. The most common way of using the inject method is to define the services as variables in the scenario and then use a beforeEach function to inject them into the scenario and assign each service to a variable accessible to each specification in the scenario.
