Rational Robot Question:

A test case describes the testable and verifiable behavior in a system. A test case can also describe the extent to which you will test an area of the application. Existing project artifacts, such as requirements, provide information about the application and can be used as test inputs for your test cases. TestManager provides built-in test input types, but almost any artifact can be used as a test input.

For example, here's what the following artifacts offer as test inputs:

* Requirements describe a condition or capability to which a system must conform.
* Visual models provide a graphic representation of a system's structure and interrelationships.
