### Question:
ClientLevelAxis extends ClientBaseAxis<ClientQueryLevel> { @Valid @XmlElementWrapper @XmlElements({ @XmlElement(name = "level", type = ClientQueryLevel.class), @XmlElement(name = "allLevel", type = ClientQueryLevel.ClientAllLevel.class), @XmlElement(name = "aggregations", type = ClientQueryLevel.ClientLevelAggregationsRef.class), }) @Override public List<ClientQueryLevel> getItems() { return super.getItems(); } ClientLevelAxis();  ClientLevelAxis(ClientLevelAxis axis);  ClientLevelAxis(Collection<? extends ClientQueryLevel> c);  ClientLevelAxis(Collection<? extends ClientQueryLevel> c, List<ClientExpandable> expansions); @XmlElementWrapper @XmlElements({ @XmlElement(name = "member", type = ClientMemberExpansion.class), @XmlElement(name = "level", type = ClientLevelExpansion.class) }) List<ClientExpandable> getExpansions(); ClientLevelAxis setExpansions(List<ClientExpandable> expansions); @Valid @XmlElementWrapper @XmlElements({ @XmlElement(name = "level", type = ClientQueryLevel.class), @XmlElement(name = "allLevel", type = ClientQueryLevel.ClientAllLevel.class), @XmlElement(name = "aggregations", type = ClientQueryLevel.ClientLevelAggregationsRef.class), }) @Override List<ClientQueryLevel> getItems(); @Override ClientLevelAxis setItems(List<ClientQueryLevel> items); @Override String toString(); @Override boolean equals(Object o); @Override int hashCode(); @Override ClientLevelAxis deepClone();  }### Answer:
@Test public void constructor_clientQueryLevel_instance() { ClientLevelAxis instance = new ClientLevelAxis(CLIENT_QUERY_LEVEL_LIST); assertEquals(CLIENT_QUERY_LEVEL_LIST, instance.getItems()); }
