### Question:
PhenoSetUnionFind { public UnionFind<TermId> getUnionFind() { return this.unionFind; } PhenoSetUnionFind(Set<TermId> hpoTermSet, Map<LoincId, Loinc2HpoAnnotationModel> annotationMap); UnionFind<TermId> getUnionFind();  }### Answer:
@Test public void checkDataStructureSetUpCorrectly() { Term term1 = hpoTermMap.get("Hypocapnia"); Term term2 = hpoTermMap.get("Hypercapnia"); assertTrue(unionFind.getUnionFind().inSameSet(term1.getId(), term2.getId())); Term term3 = hpoTermMap.get("Nitrituria"); assertFalse(unionFind.getUnionFind().inSameSet(term1.getId(), term3.getId())); }
