### Question:
ConcreteZipIO { public static Iterable<Communication> read(String fn) { try { ZipFile zf = new ZipFile(fn); return Util.read(zf); } catch (IOException e) { throw new RuntimeException(e); } }  static Iterable<Communication> read(String fn); static Stream<Communication> readAsStream(String fn); static Map<String, Communication> openAsMap(String fn); static void write(String fn, Iterable<Communication> comms); static void write(String fn, Stream<Communication> comms);  }### Answer:
@Test public void testRead() { Iterable<Communication> comms = ConcreteZipIO.read(p); for (Communication comm : comms) { assertEquals("TEST", comm.getType()); } }
