### Question:
Annotation extends ElementHeader { @Override public int hashCode() { return Objects.hash(super.hashCode(), getAnnotationType(), getSummary(), getConfidenceLevel(), getExpression(), getExplanation(), getAnalysisStep(), getJsonProperties(), getNumAttachedAnnotations(), getAnnotationStatus(), getReviewDate(), getSteward(), getReviewComment(), getAdditionalProperties(), getExtendedProperties()); } Annotation();  Annotation(Annotation template); String getAnnotationType(); void setAnnotationType(String annotationType); String getSummary(); void setSummary(String summary); int getConfidenceLevel(); void setConfidenceLevel(int confidenceLevel); String getExpression(); void setExpression(String expression); String getExplanation(); void setExplanation(String explanation); String getAnalysisStep(); void setAnalysisStep(String analysisStep); String getJsonProperties(); void setJsonProperties(String jsonProperties); AnnotationStatus getAnnotationStatus(); void setAnnotationStatus(AnnotationStatus annotationStatus); int getNumAttachedAnnotations(); void setAttachedAnnotations(int number); Date getReviewDate(); void setReviewDate(Date reviewDate); String getSteward(); void setSteward(String steward); String getReviewComment(); void setReviewComment(String reviewComment); Map<String, String> getAdditionalProperties(); void setAdditionalProperties(Map<String, String> additionalProperties); @Override String toString(); @Override boolean equals(Object objectToCompare); @Override int hashCode();  }### Answer:
@Test public void testHashCode() { assertTrue(getTestObject().hashCode() == getTestObject().hashCode()); }
