### Question:
ConceptBreakdown { public Iterable<ConceptBreakdown> getChildBreakdownInfos() { return childBreakdown; } ConceptBreakdown(String conceptCode);   ConceptBreakdown(String parentConceptCode, String conceptCode); String getConceptCode(); void setConceptCode(String code); String getParentConceptCode(); void setParentConceptCode(String parentConceptCode); Float getFactor(); void setFactor(Float factor); Float getPerformance(); void setPerformance(Float performance); Iterable<ConceptBreakdown> getChildBreakdownInfos(); ConceptBreakdown getCodeBreakdown(String conceptCode); Measurement getMeasurement(); void setMeasurement(Measurement measurement); boolean isWorkPackage(); @Override String toString();  }### Answer:
@Test public void testAddChildChapter() { boolean childFound = false; for (ConceptBreakdown childBreakdown : root.getChildBreakdownInfos()) { if (childBreakdown.equals(child)) { childFound = true; } } assertTrue(childFound); }
