Use cases define how the system or application works.

Use cases are created very early in the development cycle.

The use case is made up of a set of possible sequences of 
interactions between systems and users in a particular 
environment and related to a particular goal.

Each use case provides one or more scenarios that convey 
how the Actor (User) will interact with the System to 
achieve a specific business goal or function

Use cases are often written by business analysts and end 
users.

Using use cases we can eventually write highly detailed and 
exhaustive test cases

Use case is nothing but graphical represntation.that is 
prepared by based on the test plan. By looking at these use 
case we can easily identified the concept.

customer requirements
•A document which summarize the (projects) in Business 
activity
•Use Case is written in Business Design Document (BDD) by 
the Business Analyst
•It is for understanding the functionality for the person 
who is involved in writing the test cases
