### Question:
RegistrationClient { protected static String constructRegistrationPath(String basePath, String flavor) { StringBuilder buff = new StringBuilder().append(basePath).append("/").append(flavor); return buff.toString(); } RegistrationClient(CuratorFramework curatorFramework, String basePath,
                              String flavor, String listenAddress,
                              String serviceSpec,
                              Map<String, String> parameters);  RegistrationClient(CuratorFramework curatorFramework, String basePath,
                              String flavor, String listenAddress,
                              String serviceSpec);  RegistrationClient(CuratorFramework curatorFramework, String basePath, String flavor, String listenAddress,
                              Map<String, Integer> services); RegistrationClient advertiseAvailability(); void verifyRegistrations(); RegistrationClient deAdvertiseAvailability();  }### Answer:
@Test public void testConstructPath() { String path = RegistrationClient.constructRegistrationPath("/com/cvs", "chocolate"); assertEquals(path, "/com/cvs/chocolate"); }
