### Question:
Region { public static Region getRegion(Regions region) { return RegionUtils.getRegion(region.getName()); } Region(final String name, final String domain); static Region getRegion(Regions region); static Region getRegion(String regionString); String getName(); String getDomain(); String getServiceEndpoint(String serviceName); boolean isServiceSupported(String serviceName); boolean hasHttpsEndpoint(String serviceName); boolean hasHttpEndpoint(String serviceName); T createClient(Class<T> serviceClass,
            AWSCredentialsProvider credentials,
            ClientConfiguration config); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testRegionEquals() { final Region usWest2 = RegionUtils.getRegion("us-west-2"); final Region other = RegionUtils.getRegionByEndpoint("s3.us-west-2.amazonaws.com"); assertEquals(usWest2, other); }
