示例1: EntityManager
TEST(NAME, DestroyingEntitiesDispatchesReallocationEvent)
{
World w;
MockEntityManagerListener mock;
EntityManager* em = new EntityManager(&w);
em->event.addListener(&mock, "mock");
// uninteresting calls
EXPECT_CALL(mock, onCreateEntityHelper(testing::_))
.Times(testing::AtLeast(0));
EXPECT_CALL(mock, onDestroyEntityHelper(testing::_))
.Times(testing::AtLeast(0));
EXPECT_CALL(mock, onEntitiesReallocatedHelper(testing::_)).Times(testing::AtLeast(0)); // ignore this call during entity creation - not important
em->createEntity("entity1"); // will be destroyed via destroyEntities()
em->createEntity("entity2"); // will be via destroyAllEntities
// expect 4 calls, since 4 entities are being destroyed
EXPECT_CALL(mock, onEntitiesReallocatedHelper(testing::_))
.Times(4); // 4 entities were created...
em->destroyEntities("entity1");
em->destroyAllEntities();
Entity& e = em->createEntity("entity3");
em->destroyEntity(e);
em->createEntity("entity4"); // destroyed by destructor
delete em;

int main() {
