hi hikalkan ,

   First,my project based on ABP created two dbcontext. I have modified the method 'UsingDbContext'  of AbpTestBase as generic method to initialize two dbcontext data at AppTestBase intialize. The modified method like below:

protected void UsingDbContext<TDbContext>(Action<TDbContext> action)
            where TDbContext:AbpDbContext
        {
            using (var context = LocalIocManager.Resolve<TDbContext>())
            {
                context.DisableAllFilters();
                action(context);
                context.SaveChanges();
            }
        }     
  
Below is AbpTestBase construction method :

 protected AppTestBase()
        {
            //Seed initial data
            UsingDbContext<HWWLDbContext>(context =>
            {
                new InitialDbBuilder(context).Create();
                new TestDataBuilder(context).Create();
            });
            LoginAsDefaultTenantAdmin();
           
            UsingDbContext<SecondHWWLDbContext>(secondSontext =>
            {
                new LMTestDataBuilder(secondSontext,AbpSession.TenantId.Value).Create();
            });
        }

Below is LMTestDataBuilder.cs :
public class LMTestDataBuilder
    {
        private readonly int _tenantId;
        private readonly SecondHWWLDbContext _secondContext;

        public LMTestDataBuilder(SecondHWWLDbContext secondContext,int tenantId)
        {
            _tenantId = tenantId;
            _secondContext = secondContext;
        }

    
        public void Create()
        {
            _secondContext.DisableAllFilters();
            CreateCargo();
            _secondContext.SaveChanges();
        }
        public void CreateCargo()
        {
            var cargo = new Cargo 
            {
                Id = GuidHelper.GetCombinedGuid(),
                TenantId = _tenantId,
                OperationTime = DateTime.Now,
                InternalNumber = "TR1001",
                CargoName = "Car",
                NumberOfPackage = 100,
                DeliveryAmount = 100,
                ChargeAmount = 100,
                RowVersion=Encoding.UTF8.GetBytes(Guid.NewGuid().ToString())

            };
            _secondContext.Cargoes.Add(cargo);
        }
    }

it threw the exception : '{"Table 'AndCargoes' was not found. The database was probably not initialized.\r\n\r\nIf using CodeFirst try to add the following line:\r\ncontext.Database.CreateIfNotExists()"}' when initializing the second dbcontext data.

Hi hikanlkan,

I met the error 'The sequence does not contain any matching elements' when I did the unit test of abp. I took me a long time to find the error code. My entity has the column attribute for one property like that: [Column(TypeName = "varchar")] public virtual string Picture { get; set; }

When I used the method of UsingDbContext of AppTestBase , the error was throw. I don't konw why the column attribute causes the error?

Hi hikanlkan, When I used the Unit Test of ABP , the error like 'The sequence does not contain any matching elements' happend in the method 'Initialize' of AbpDbContext. It took me a long time to find the error code . I found the error was caused by one property of an entity was added the attribute 'Column',like that :

[Column(TypeName = "varchar")] public virtual string Picture { get; set; }

But, I learnt some aout Code First , which has the attribute of 'Column', so why the column attribute caused the error? Thank you .
