You only have to test that a browser window actually opened.

1. First, build a collection 'A' of all currently open windows.
2. Now do 'aWindow := Browser open'.
3. Now build another collection 'B' of all currently open windows
4. Is size of collection 'B' one greater than size of collection 'A'?
5. Is 'aWindow' the exact same window as the extra window in 'B'?
6. Send 'aWindow close' (or 'aWindow window close', depending on the 
dialect)
7. Now build a collection 'C' of all currently open windows.
8. Is collection 'A' the same size as collection 'C'?
9. Does collection 'A' have the same elements as collection 'C'?
