  Hi @aaron,

  This is my test code:

  public class CategoryAppService_Tests : AppTestBase
      {
          private readonly ICategoryAppService _categoryAppService;
  
          public CategoryAppService_Tests()
          {
              _categoryAppService = Resolve<ICategoryAppService>();
          }
  
          [Fact]
          public async Task Should_Get_All_Categories_Without_Any_Filter()
          {
              //Act
              var categories = await _categoryAppService.GetCategories(new GetCategoriesInput());
  
              //Assert
              categories.Items.Count.ShouldBe(2);
          }
      }
  

  This is my service code:

  public class CategoryAppService : IpsAppServiceBase, ICategoryAppService
      {
          private readonly IRepository<Category> _categoryRepository;
  
          public CategoryAppService(IRepository<Category> categoryRepository)
          {
              _categoryRepository = categoryRepository;
          }
  
          public async Task<ListResultDto<CategoryListDto>> GetCategories(GetCategoriesInput input)
          {
              var categories = await _categoryRepository
                  .GetAll()
                  .WhereIf(
                      !input.Filter.IsNullOrEmpty(),
                      c => c.Title.Contains(input.Filter) ||
                           c.Description.Contains(input.Filter)
                  )
                  .OrderBy(c => c.Title)
                  .ToListAsync();
  
              return new ListResultDto<CategoryListDto>(categories.MapTo<List<CategoryListDto>>());
          }
      }

  And this is my entity, dto, mapping and interface code:

  public class Category : FullAuditedEntity
      {
          [Required]
          [MaxLength(CategoryConsts.MaxTitleLength)]
          public virtual string Title { get; set; }
  
          [Required]
          [MaxLength(CategoryConsts.MaxDescriptionLength)]
          public virtual string Description { get; set; }
  
          [MaxLength(CategoryConsts.MaxTypeLength)]
          public virtual string Type { get; set; }
      }
  

  public class CategoryListDto : FullAuditedEntityDto
      {
          public string Title { get; set; }
  
          public string Description { get; set; }
  
          public string Type { get; set; }
      }
  

  public class GetCategoriesInput
      {
          public string Filter { get; set; }
      }
  

  configuration.CreateMap<Category, CategoryListDto>();
  

  public interface ICategoryAppService : IApplicationService
      {
          Task<ListResultDto<CategoryListDto>> GetCategories(GetCategoriesInput input);
      }

  I really don't know which object, because I just follow the sample and these above are all my codes. As instructed, I also set the MultiTenancyEnabled = false.

  Looking at the error message, I guess something wrong happens in the DefaultSettingsCreator (come with the aspnet zero). Can you have a look at the error message, please?

  Thank you

  Hi @aaron,

  I have fixed the issue as instructed:

  if (IpsConsts.MultiTenancyEnabled == false)
              {
                  //var defaultTenant = _context.Tenants.IgnoreQueryFilters().FirstOrDefault(t => t.TenancyName == MultiTenancy.Tenant.DefaultTenantName);
                  //tenantId = defaultTenant.Id;
                  tenantId = MultiTenancyConsts.DefaultTenantId;
              }
  

  But I still cannot pass the test, here is the error message:

  I guess the test project of version 6.9.1 is not stable. Could you have a look, please?

  From Object To Object Mapping - Unit Tests:

  1. Always use IObjectMapper, do not use MapTo extension methods.

  Change:

  - categories.MapTo<List<CategoryListDto>>()
  + ObjectMapper.Map<List<CategoryListDto>>(categories)

  hi @dzungle

  You search to see if it is called at another layer. The default should be called in the web.core layer.

  Configuration.Modules.Zero().LanguageManagement.EnableDbLocalization();

  Hi @maliming

  I found one more call in the TestBaseModule (Test.Base project).

  

  How can I solve this issue?
