*
* <p>For setting up a full WebApplicationContext in a test environment, you can

*
* <p>A common setup is to point your JVM working directory to the root of your
* web application directory, in combination with filesystem-based resource loading.
* This allows to load the context files as used in the web application, with
* relative paths getting interpreted correctly. Such a setup will work with both
* FileSystemXmlApplicationContext (which will load straight from the file system)
* and XmlWebApplicationContext with an underlying MockServletContext (as long as
* the MockServletContext has been configured with a FileSystemResourceLoader).
