### Question:
DataSetHelper { public abstract IndividualHelper relativeIndividual(Name<?> name, String managerId, URI path); DataSetHelper(); abstract S replace(Serializable from, T to, Class<? extends S> clazz); abstract ManagedIndividual manage(ManagedIndividualId id); abstract T self(); abstract T relative(URI path); abstract IndividualHelper externalIndividual(URI uri); abstract IndividualHelper managedIndividual(Name<?> name, String managerId); abstract IndividualHelper relativeIndividual(Name<?> name, String managerId, URI path); abstract IndividualHelper localIndividual(Name<?> name); static final URI SELF; }### Answer:
@Test public void testCreatesRelativeIndividualIfItDoesNotExist() throws Exception { DataSet dataSet = exampleDataSet(); DataSetUtils. newHelper(dataSet). relativeIndividual(name("other"),MANAGER_ID,RELATIVE_PATH); Individual<?,?> individual = dataSet. individualOfId(relativeIndividualId("other", MANAGER_ID, RELATIVE_PATH)); assertThat(individual,notNullValue()); }
