Scenario Vs Test case

[Cookiebug]

Can anyone explain to me what a 'scenario' is from a UML point of view.  Until now I have viewed a 'scenario' as a test case but they are obviously dealt with seperately with the facility to import 'scenarios'.  Should the 'scenario' writing be part of the analysis stage and then form the basis of my testing via the import?  Or, should I be writing the 'scenarios' as a tester and then importing them into the test plan?

Forgive my ignorance but this is all very new to me.

In short terms: Scenarios are templates for test cases. Try to create a scenario by selecting an element and right clicking in the scenario window. Now you can create new templates. Later when opening the test window, you can import these by right clicking and selecting import.

Just to add additional commentary:

A scenario in UML is a particular instantiation of a Use Case. For example, instead of saying the *Actor does* you would say *Bill, marketing manager, does..." and use specific values to exercise the path through the Use Case. In essence, that is what it is - one path through a Use Case.
