/**
 * Mock ServletConfig object for low-level unit tests of
 * Struts controller components.  Coarser grained tests should be implemented
 * in terms of the Cactus framework, instead of the mock object classes.
 *
 * WARNING - Only the minimal set of methods needed to
 * create unit tests is provided, plus additional methods to configure this
 * object as necessary.  Methods for unsupported operations will throw
 * UnsupportedOperationException.
 *
 * WARNING - Because unit tests operate in a single
 * threaded environment, no synchronization is performed.
