What are the components of a use case?

An actor can be a person, an organization, or an outside system that interacts with your application or system. … System: A specific sequence of actions and interactions between actors and the system. … Goals: The end result of most use cases.
What is use cases in testing?
Use case testing is a technique that helps to identify test cases that cover the entire system, on a transaction by transaction basis, from start to finish. It is a description of a particular use of the system by a user. It is used widely in developing tests or systems for acceptable levels.
How do you build a use case scenario?
Developing Use Case Diagrams & Use Case ScenariosReview the business specifications and identify the actors involved.Identify the high-level events and develop the primary use cases that describe those events and how the actors initiate them. … Review each primary use case to determine the possible variations of flow through the use case.
What is an actor in a use case?
An actor in the Unified Modeling Language (UML) “specifies a role played by a user or any other system that interacts with the subject.” “An Actor models a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data), but which is external to the subject.”

What information is provided by use cases or a use case diagram?
A purpose of use case diagram is to capture core functionalities of a system and visualize the interactions of various things called as actors with the use case. This is the general use of a use case diagram. The use case diagrams represent the core parts of a system and the workflow between them.
