diagrams, are used to describe the test processes themselves. SysML knows a
model element called test case . This model element produces a connecting link
to the UML testing profi le [53], which defi nes additional model elements like test
context and test components .
You can start very early to build your test model. As soon as you have fi nished
identifying the fi rst bunch of requirements, you can think about the pertaining
test cases. This highlights the fact that it must be verifi able whether or not a
requirement is satisfi ed. The further you detail your requirements, the more details
of your tests you can describe. For example, every possible traversal through a use
case activity is a potential test case ( Figure 2.90 ).
The test model grows in parallel with the system model.
