What is a use case and how are they used?
- A Use Case is a detailed description of a user's interaction with a system
- The only requirements are an actor and an object to be acted upon
A Use Case consists of seven components:
- Name – represented in the form of an action
- Description
- Preconditions – criteria that must be met before the execution of the scenario
- Scenario – anticipated series of actions and responses
- Results
- Alternate Paths – variations on the scenario. Represent failures in the system.
