    Use case testing
    - Tests can be specified from use cases or business scenarios.

    - A use case describes interactions between actors, including users and the system, which produce a result of value to a system user.

    - Each use case terminates with post- conditions which are the observable results and final state of the system after the use case is completed.

    - It generally has a mainstream scenario, and sometimes alternative branches.

    - Use cases describe the "process flow" through a system based on its actual likely use, so the TCs derived from use cases are most useful in uncovering defects in the process flows during real-world use of the system.

    - Use cases, often referred to as scenarios are very useful for designing acceptance tests with customer/user participation.

    - They also help uncover integration defects caused by the interaction and interference of different components, which individual component testing would not reveal.
