/**

* controllers and their dependencies similar to plain unit tests, and also
* making it possible to test one controller at a time.
*
* This builder creates the minimum infrastructure required by the
* {@link DispatcherServlet} to serve requests with annotated controllers and
* also provides methods for customization. The resulting configuration and
* customization options are equivalent to using MVC Java config except
* using builder style methods.
*
*
To configure view resolution, either select a "fixed" view to use for every
* request performed (see {@link #setSingleView(View)}) or provide a list of
* {@code ViewResolver}s (see {@link #setViewResolvers(ViewResolver...)}).
