In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.

They tend to require more complex configurations, a message/job queue manager, like RabbitMQ or Redis, but they allow you to run background tasks in multiple processes, and especially, in multiple servers.

There will be three items in the task list for this dataset.

The stubs also exist at different "levels", where one test might wire stubs into a specific live implementation.
In the next test that same "live implementation" will be used in a stub version instead.

Not all live services have stubs, but can be added as needed.
