Outline View
Purpose: To test the Outline view in Eclipse.  The Outline view is
just a container for the pages contributed by open editors.  Therefore,
this test will focus on the creation, show, and closure of those pages.
Setup:
- 
Install Eclipse Platform.
- 
Create a java project containing three java files and a text file.
Method:
- 
Start the workbench.
- 
If any editor is open close it.
- 
Verify that the Outline view is empty and contains the text "An Outline
is not available".
- 
Open an editor on a java file. Verify that a java page appears in the outline
view.  If you select items in this page the scroll and selected text
within the editor should change.
- 
Open a second file in a java editor.  Verify that a second java page
appears in the outline view.
- 
If you switch between the two editors the visible page should change.
- 
Open a .txt file in a text editor.  When this editor is active the
outline view will be empty and contain the standard empty text as described
in step 2.
- 
If you switch between a text and java editor the visible page should change. 
Verify that the toolbar and menu items in the outline also chnage. 
The java editor has Field and Member toolbar items.
- 
Close one editor.  If another editor is activated verify that its
outline page is now visible.  If no editor is activated verify that
the outline is empty.
- 
Close the last editor and verify that the default blank page is visible
in the outline.
