Example 11 with MockEventManager

use of org.apache.cayenne.event.MockEventManager in project cayenne by apache.

the class ClientChannelTest method testOnQuerySelectOverrideCached.

@Test
public void testOnQuerySelectOverrideCached() {
    ObjEntity entity = new ObjEntity("test_entity");
    entity.setClassName(MockPersistentObject.class.getName());
    DataMap dataMap = new DataMap("test");
    dataMap.addObjEntity(entity);
    Collection<DataMap> entities = Collections.singleton(dataMap);
    EntityResolver resolver = new EntityResolver(entities);
    CayenneContext context = new CayenneContext();
    context.setEntityResolver(resolver);
    ObjectId oid = new ObjectId("test_entity", "x", "y");
    MockPersistentObject o1 = new MockPersistentObject(oid);
    context.getGraphManager().registerNode(oid, o1);
    assertSame(o1, context.getGraphManager().getNode(oid));
    // another object with the same GID ... we must merge it with cached and return
    // cached object instead of the one fetched
    MockPersistentObject o2 = new MockPersistentObject(oid);
    MockClientConnection connection = new MockClientConnection(new GenericResponse(Arrays.asList(o2)));
    ClientChannel channel = new ClientChannel(connection, false, new MockEventManager(), false);
    context.setChannel(channel);
    QueryResponse response = channel.onQuery(context, new SelectQuery("test_entity"));
    assertNotNull(response);
    List<?> list = response.firstList();
    assertNotNull(list);
    assertEquals(1, list.size());
    assertTrue("Expected cached object, got: " + list, list.contains(o1));
    assertSame(o1, context.getGraphManager().getNode(oid));
