/**
 * Test datastore handling (create, read and update):
 * 
 * <ul>
 * <li>Tests all the constructors and setters from {@link GSDirectoryOfShapefilesDatastoreEncoder} and parent classes (
 * {@link GSShapefileDatastoreEncoder}, {@link GSAbstractDatastoreEncoder}).
 * 
 * <li>Tests constructors and getters from {@link RESTDataStore} (reader).
 * 
 * <li>Tests {@link GeoServerRESTDatastoreManager} create and update methods.
 * </ul>
 * 
 * <p>
 * The sequence is:
 * <ol>
 * <li>Create a DirectoryOfShapefilesDatastoreEncoder, with default parameters.
 * <li>Publish via GeoServerRESTDatastoreManager.create.
 * <li>Read the datastore from server.
 * <li>Test all parameter values.
 * <li>Create a new Encoder from it.
 * <li>Change all datastore parameter to non-default ones.
 * <li>Update via GeoServerRESTDatastoreManager.update.
 * <li>Read again.
 * <li>Test all new values.
 * </ol>
