### Question:
DiagnosisHittingSet { public List<DiagnosisElement> getDiagnosisElements() { return diagnosisElements; } DiagnosisHittingSet(List<DiagnosisElement> diagnosisElements); List<DiagnosisElement> getDiagnosisElements(); boolean covers(DiagnosisHittingSet other); boolean contains(DiagnosisElement otherElement); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test void testOrderedListOfDiagnosisElements() { final DiagnosisHittingSet a = new DiagnosisHittingSet(asList( new DiagnosisElement(1, new int[] {0}, new int[]{2}), new DiagnosisElement(5, new int[] {0, 1}, new int[]{1, 2}), new DiagnosisElement(4, new int[] {0, 1}, new int[]{0, 2}))); assertEquals(1, a.getDiagnosisElements().get(0).getDiagnosedConstraintId()); assertEquals(4, a.getDiagnosisElements().get(1).getDiagnosedConstraintId()); assertEquals(5, a.getDiagnosisElements().get(2).getDiagnosedConstraintId()); }
