Jest Test TypeORM EntityManager cannot retrive inserted entities

I'm running integration tests similar to this, if I try to check database contents the query do not find inserted rows. Does the EntityManager use diffrent connections ? or I need to "flush" in some ways ( I do no know how ) ? The manager.save works with success, I see in typeORM logs the insert without errors and generated id of entities are filled.

   test('should be retived ', async () => {
            const manager = getManager();
        
            await manager.save(item_1);
        
            const result = await manager.createQueryBuilder()
            .select()
            .from(EntityTypeX, "x")
            .getMany();
        
            expect(result).toHaveLength(1) //This return zero
        
          });
..
    beforeAll( async () => {
        return opneDBCconnection();
    });
    beforeEach( async () => {
       // Clenaup
       getManager().createQueryBuilder()
      .delete()
      .from(Sms)
      .execute();    
    });
