### Question:
MetadataIdentificationUtils { public static boolean isIdentifyingInstance(final String metadataIdentificationString) { return isValid(metadataIdentificationString) && metadataIdentificationString.contains(INSTANCE_DELIMITER) && !metadataIdentificationString.endsWith(INSTANCE_DELIMITER); } private  MetadataIdentificationUtils(); static String create(final Class<?> metadataClass); static String create(final String fullyQualifiedClassName); static String create(final String fullyQualifiedMetadataClass,
      final String instanceIdentificationKey); static String getMetadataClass(final String metadataId); static String getMetadataClassId(final String metadataId); static String getMetadataInstance(final String metadataId); static boolean isIdentifyingClass(final String metadataIdentificationString); static boolean isIdentifyingInstance(final String metadataIdentificationString); static boolean isValid(final String metadataIdentificationString);  }### Answer:
@Test public void testClassMidIsNotInstanceMid() { assertFalse(MetadataIdentificationUtils.isIdentifyingInstance(CLASS_MID)); }
@Test public void testInstanceMidIsInstanceMid() { assertTrue(MetadataIdentificationUtils.isIdentifyingInstance(INSTANCE_MID)); }
