### Question:
ClientQueryAggregatedField implements ClientField, ClientAggregate, ClientFieldReference, ClientIdentifiable<String>, ClientQueryExpression, DeepCloneable<ClientQueryAggregatedField> { @Override public void accept(ClientQueryVisitor visitor) { if (this.expressionContainer != null) { this.expressionContainer.getObject().accept(visitor); } visitor.visit(this); } ClientQueryAggregatedField();  ClientQueryAggregatedField(ClientQueryAggregatedField field); @Override String getId(); ClientQueryAggregatedField setId(String id); @Override @XmlTransient String getName(); @Override @XmlElement(name = "type") String getType(); ClientQueryAggregatedField setType(String type); @Override @XmlElement(name = "fieldRef") String getFieldReference(); ClientQueryAggregatedField setFieldReference(String fieldRef); @Override @XmlElement(name = "functionName") String getAggregateFunction(); ClientQueryAggregatedField setAggregateFunction(String aggregateFunction); @Override @XmlElement(name = "timeBalanceFunctionName") String getAggregateFirstLevelFunction(); ClientQueryAggregatedField setAggregateFirstLevelFunction(String aggregateFirstLevelFunction); @Override @XmlTransient String getAggregateExpression(); @XmlElement(name = "expression") ClientExpressionContainer getExpressionContainer(); ClientQueryAggregatedField setExpressionContainer(ClientExpressionContainer expressionContainer); @Deprecated @Override @XmlElement(name = "arg") String getAggregateArg(); @Deprecated ClientQueryAggregatedField setAggregateArg(String aggregateArg); @Override @XmlTransient String getAggregateType(); ClientQueryAggregatedField setAggregateType(String aggregateType); ClientQueryAggregatedField setDataSourceField(ClientDataSourceField field); @Deprecated String getSecondAggregateField(); @Override void accept(ClientQueryVisitor visitor); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString(); @Override ClientQueryAggregatedField deepClone();  }### Answer:
@Test void accept_without_ExpressionContainer() { ClientQueryAggregatedField instance = new ClientQueryAggregatedField(); instance.accept(clientELVisitor); verify(clientELVisitor).visit(instance); }
