### Question:
NamingRequestObjectBuilder { public Deleteelement deleteElementMapper(String instanceGroupId) { Deleteelement deleteElement = new Deleteelement(); deleteElement.setExternalKey(instanceGroupId); return deleteElement; }  Element elementMapper(String instanceGroupId, String policyInstanceName, String namingType,
            String nfNamingCode, String instanceGroupName); Deleteelement deleteElementMapper(String instanceGroupId); NameGenRequest nameGenRequestMapper(List<Element> elements); NameGenDeleteRequest nameGenDeleteRequestMapper(List<Deleteelement> deleteElements);  }### Answer:
@Test public void deleteElementMapperTest() { Deleteelement expected = new Deleteelement(); expected.setExternalKey(instanceGroupId); Deleteelement actual = mapper.deleteElementMapper(instanceGroupId); assertThat(actual, sameBeanAs(expected)); }
