Structured Specification Tab
The Structured Specification tab offers a wide range of facilities for generating and modifying scenario specifications, enabling you to define the structure, actions and interactions of the scenarios defined for an element such as a Use Case. These scenarios can be the main (basic) path, alternate paths or exception paths.
When you open the Structured Specification tab it defaults to the basic path so that if it does not already exist, you can create it. You can create alternate paths and exception paths as part of the process of adding them to steps of the basic path.
You can also create all three types of scenario paths on the Description tab, or in the Scenarios & Requirements window.
