I have two entities Entity1 and Entity2. When I'm running test case to create Entity1, It's giving me the below error.

sqlite error 19 'foreign key constraint failed'

        #endregion

        #region Private Methods

        private async Task<FetchEntity1> CreateNewEntity1(string sku)
        {
            FetchEntity2 entity2 = await entity2Base.AddEntity2ToDBAsync(entity2Base.CreateEntity2Entity(
                Entity2TestBase.K_TESTENTITYCODE1,
                Entity2TestBase.K_TESTDESC1
                ));

            return await AddEntity1ToDBAsync(CreateEntity1Entity(sku, entity2.Id));
		}
        #endregion
    }
}

namespace MyCompany.MyProject.Tests.AppTestBases
{
    public class Entity2TestBase : AppTestBase
    {
		public async Task<FetchEntity2> AddEntity2ToDBAsync(Entity2Input entity2Dto)
		{
			await _entity2AppService.CreateEntity2(entity2Dto);
			await CleanQueue();

			var entity2s = _entity2AppService.GetSearchEntity2(
				new FetchEntity2Input() { Entity2Code = entity2Dto.Entity2Code, LanguageCode = AppConsts.DefaultLanguageCode }
				);

			return entity2s.Items.First();
		}
	}
}

But When I replace method CreateNewEntity1 with the below method it works fine.

private async Task<Entity1DetailsDto> CreateNewEntity1(string sku)
{
	var entity2 = entity2Base.CreateEntity2Entity(
		Entity2TestBase.K_TESTENTITY2CODE1,
		Entity2TestBase.K_TESTDESC1
		);

	await _entity2AppService.CreateEntity2(entity2);

	var entity2List = _entity2AppService.GetSearchEntity2(new FetchEntity2Input()
	{ 
		Entity2Code = entity2.Entity2Code
	});
	
	return CreateEntity1Entity(sku, entity2List.Items.First().Id);

}

So why is it failing in the first case? Even if I'm passing the inserting the correct value of Entity2Id in the Entity1 table. And why is it working if I 'm calling _entity2AppService.CreateEntity2(entity2) inside Entity1AppService_Test class. Is it related to Context? or this record is deleted for Entity2 when I'm returning from AddEntity2ToDBAsync method?

How can I verify the SQLite table records? Is there any way to check tables once test case is finished or during test case execution?
