"Systems Engineering with SysML/UML: Modeling, Analysis, Design"

This profi le
consists of a set of stereotypes you can use to extend your SysML or UML toolbox
and test vocabulary.
As far as testing is concerned there is only a test case in SysML. This element is
probably suffi cient for simple models. However, it was primarily defi ned to create a
kind of basis for a more extensive testing languages, such as the UML Testing Profi le .
A test case is a stereotype for the model elements behavior ??”that is, activity,
interaction, state machine, and free behavior 3
??”and operation . You can use these
elements for a detailed and executable description of a test case (i.e., describing
concrete executable testing steps). The notation is a rectangle with the name of
the test case and the stereotype ?«testCase?» ( Figure 4.15 ).
4.3.8 Refi ne Relationship
Defi nition
A refine relationship specifies that a model element describes the properties
of a requirement in more detail.
It is a standard stereotype ?«refine?» of the UML abstraction relationship.
