### Question:
ClientRangeBoundary implements ClientExpression<ClientRangeBoundary>, DeepCloneable<ClientRangeBoundary> { @XmlElements({ @XmlElement(name = ClientNumber.EXPRESSION_ID, type = ClientNumber.class), @XmlElement(name = ClientString.EXPRESSION_ID, type = ClientString.class), @XmlElement(name = ClientBoolean.EXPRESSION_ID, type = ClientBoolean.class), @XmlElement(name = ClientDate.EXPRESSION_ID, type = ClientDate.class), @XmlElement(name = ClientTimestamp.EXPRESSION_ID, type = ClientTimestamp.class), @XmlElement(name = ClientTime.EXPRESSION_ID, type = ClientTime.class), @XmlElement(name = ClientVariable.EXPRESSION_ID, type = ClientVariable.class), @XmlElement(name = ClientFunction.EXPRESSION_ID, type = ClientFunction.class) }) public ClientExpression getBoundary() { return boundary; } ClientRangeBoundary();  ClientRangeBoundary(ClientLiteral literal);  ClientRangeBoundary(ClientExpression literal);  ClientRangeBoundary(ClientRangeBoundary boundary); @XmlElements({ @XmlElement(name = ClientNumber.EXPRESSION_ID, type = ClientNumber.class), @XmlElement(name = ClientString.EXPRESSION_ID, type = ClientString.class), @XmlElement(name = ClientBoolean.EXPRESSION_ID, type = ClientBoolean.class), @XmlElement(name = ClientDate.EXPRESSION_ID, type = ClientDate.class), @XmlElement(name = ClientTimestamp.EXPRESSION_ID, type = ClientTimestamp.class), @XmlElement(name = ClientTime.EXPRESSION_ID, type = ClientTime.class), @XmlElement(name = ClientVariable.EXPRESSION_ID, type = ClientVariable.class), @XmlElement(name = ClientFunction.EXPRESSION_ID, type = ClientFunction.class) }) ClientExpression getBoundary(); ClientRangeBoundary setBoundary(ClientExpression bound); @Override boolean equals(Object o); @Override int hashCode(); @Override ClientRangeBoundary deepClone(); @Override void accept(ClientELVisitor visitor); @Override String toString();  }### Answer:
@Test public void constructor_clientLiteral_instance() { ClientLiteral clientLiteral = new ClientNull(); ClientRangeBoundary instance = new ClientRangeBoundary(clientLiteral); assertEquals(clientLiteral, instance.getBoundary()); }
@Test public void constructor_clientExpression_instance() { ClientRangeBoundary instance = new ClientRangeBoundary(BOUNDARY); assertEquals(BOUNDARY, instance.getBoundary()); }
