Using of
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/HasWidgets.htmlis
a better idea. If HasWidgets interface is used then you can use the
presenter in a simple unit test without the extension of GWTTestCase cause
the Widget is provided to the HasWidgets's add method as an argument.
