### Question:
K4ReplicationProcess { public static String pidFrom(String urlPath) { if (urlPath ==null) return ""; int indexOf = urlPath.indexOf("uuid:"); if (indexOf>=0) { String subString = urlPath.substring(indexOf); if (subString.endsWith("/")) return subString.substring(0, subString.length()-1); else return subString; } else return ""; }  @Process static void replications(@ParameterName("url") String url, @ParameterName("username") String userName, @ParameterName("pswd") String pswd,
                                    @ParameterName("replicateCollections") String replicateCollections,
                                    @ParameterName("replicateImages") String replicateImages,
                                    @ParameterName("previousProcess")String previousProcessUUID); static void handleValidation(String handle); static void restart(String processUUID, File previousProcessFolder, String url, String userName, String pswd, String replicateCollections, String replicateImages, Phase[] phases); static void start(String url, String userName, String pswd, String replicateCollections,String replicateImages,Phase[] phases); static boolean isPhaseCompleted(File previousFolder, Phase phase); static String prepareURL(String url, String replicationCollections); static String descriptionURL(String url); static String foxmlURL(String url, String pid,String replicationCollections); static String imgOriginalURL(String url, String pid); static String pidFrom(String urlPath); static Phase[] PHASES; }### Answer:
@Test public void pidFrom() { String goodURL = "http: String goodPid = K4ReplicationProcess.pidFrom(goodURL); Assert.assertTrue("uuid:XXXXX".equals(goodPid)); String badUrl = "darmomluvit"; String badPid = K4ReplicationProcess.pidFrom(badUrl); Assert.assertTrue("".equals(badPid)); }
