what is the format for usecase?

Answer Posted / rao

Introduction
---------------
Describe a quick background of the use case.

Actors
---------
List the actors that interact and participate in this use
case.

Pre-conditions
----------------
Pre-conditions that need to be satisfied for the use case
to perform.

Post-conditions
------------------
Define the different states in which you expect the system
to be in, after the use case executes.

Basic Flow
-------------
List the primary events that will occur when this use case
is executed.

Alternative flows?
--------------------
Any subsidiary events that can occur in the use case should
be separately listed. List each such event as an
alternative flow. A use case can have as many alternative
flows as required.

Special Requirements
------------------------
Business rules for the basic and alternative flows should
be listed as special requirements in the use case
narration. These business rules will also be used for
writing test cases. Both success and failure scenarios
should be described here.

Use case relationships
------------------------
For complex systems, it is recommended to document the
relationships between use cases. Listing the relationships
between use cases also provides a mechanism for
traceability.
