Use case Derived Test Cases
- Categorized in: TESTING TOOLS
Use Cases are used to specify the required functionality of an Object-Oriented system. Test cases that are derived from use cases take advantage of the existing specification to ensure good functional test coverage of the system.
A Use Case is a top level category of system functionality, (i.e.: Log on, Shut down, etc.). A Use Case has graphical representation, Figure 3, and a text description. The diagram identifies all the actors (outside of the system) involved in the function, as well as an indication of how the Use Case is initiated. The collection of Use Case diagrams provides a ‘context’ diagram of system interfaces. Each Use Case constitutes a complete list of events initiated by an Actor and it specifies the interaction that takes place between an Actor and the System.. In a Use Case the system is viewed as opaque, where only the inputs, outputs, and functionality matter.
