### Question:
Machines { @Deprecated public static Maybe<SshMachineLocation> findUniqueSshMachineLocation(Iterable<? extends Location> locations) { return findUniqueMachineLocation(locations, SshMachineLocation.class); }  static Maybe<String> getSubnetHostname(Location where); static Maybe<String> getSubnetIp(Location where); @SuppressWarnings("unchecked") static Maybe<T> findUniqueElement(Iterable<?> items, Class<T> type); @Deprecated static Maybe<SshMachineLocation> findUniqueSshMachineLocation(Iterable<? extends Location> locations); static Maybe<MachineLocation> findUniqueMachineLocation(Iterable<? extends Location> locations); static Maybe<T> findUniqueMachineLocation(Iterable<? extends Location> locations, Class<T> clazz); static Maybe<String> findSubnetHostname(Iterable<? extends Location> ll); static Maybe<String> findSubnetHostname(Entity entity); static Maybe<String> findSubnetOrPublicHostname(Entity entity); static Maybe<String> findSubnetOrPrivateIp(Entity entity); static Maybe<String> findSubnetIp(Entity entity); static Maybe<String> findSubnetIp(Iterable<? extends Location> ll); static boolean warnIfLocalhost(Collection<? extends Location> locations, String message);  }### Answer:
@Test @SuppressWarnings("deprecation") public void testFindUniqueSshMachineLocation() throws Exception { assertEquals(Machines.findUniqueSshMachineLocation(ImmutableList.of(sshMachine, otherLoc)).get(), sshMachine); assertFalse(Machines.findUniqueSshMachineLocation(ImmutableList.of(otherLoc)).isPresent()); }
