Can't create component as it has dependencies to be satisfied in ASP.NET Boilerplate

Question

I am getting an error while running a test. How do I solve this?

public class TestAppService : TestAppServiceBase, ITestAppService
{
    private readonly ITestRepository _testRepository;
    public TestAppService(ITestRepository testRepository)
    {
        _testRepository = testRepository;
    }
}

public class TestAppService_Test : TestAppServiceTestBase
{
    private readonly ITestAppService _testAppService;
    public TestAppService_Test()
    {
        _testAppService = Resolve<ITestAppService>();
    }
}

The repository:

public class TestRepository : TestRepositoryBase<Test, int>, ITestRepository
{
    private readonly IActiveTransactionProvider _transactionProvider;
    public TestRepository(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }

    public TestRepository(IDbContextProvider<TestDbContext> dbContextProvider,
        IActiveTransactionProvider transactionProvider, IObjectMapper objectMapper)
    : base(dbContextProvider)
    {
        _transactionProvider = transactionProvider;
        ObjectMapper = objectMapper;
    }
}

public interface ITestRepository : IRepository<Test, int>
{
}

public class TestRepositoryBase<TEntity, TPrimaryKey> : EfCoreRepositoryBase<TestDbContext, TEntity, TPrimaryKey>
    where TEntity : class, IEntity<TPrimaryKey>
{
    public IObjectMapper ObjectMapper;
    public TestRepositoryBase(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}

/// <summary>
/// Base class for custom repositories of the application.
/// This is a shortcut of <see cref="TestRepositoryBase{TEntity,TPrimaryKey}"/> for <see cref="int"/> primary key.
/// </summary>
/// <typeparam name="TEntity">Entity type</typeparam>
public class TestRepositoryBase<TEntity> : TestRepositoryBase<TEntity, int>
    where TEntity : class, IEntity<int>
{
    public TestRepositoryBase(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}

The error:

Castle.MicroKernel.Handlers.HandlerException : Can't create component 'ABC.XYZ.Business.Services.PQR.TestAppService' as it has dependencies to be satisfied.

'ABC.XYZ.Business.Services.PQR.TestAppService' is waiting for the following dependencies:
- Service 'ABC.XYZ.Business.Repositories.Interfaces.ITestRepository' which was not registered.

Add DbSet<Test> in your DbContext:

public class TestDbContext : AbpDbContext
{
    public DbSet<Test> Tests { get; set; }

    public TestDbContext(DbContextOptions<TestDbContext> options)
        : base(options)
    {
    }
}

Add AutoRepositoryTypes to your DbContext:

[AutoRepositoryTypes(
    typeof(IRepository<>),
    typeof(IRepository<,>),
    typeof(TestRepositoryBase<>),
    typeof(TestRepositoryBase<,>)
)]
public class TestDbContext : AbpDbContext
{
    ...
}

Target does not implement interface Abp.Domain.Repositories.IRepository`1[[Abp.Localization.Appl‌​icationLanguage, Abp.Zero.Common, Version=2.3.0.0, Culture=neutral, PublicKeyToken=null]] Parameter name: target

Register TestRepository:

Configuration.ReplaceService<IRepository<Test, int>>(() =>
{
    IocManager.IocContainer.Register(
        Component.For<IRepository<Test, int>, ITestRepository, TestRepository>()
            .ImplementedBy<TestRepository>()
            .LifestyleTransient()
    );
});

Explanation:

When you inject ITestRepository, it tries to instantiate IRepository<Test, Int> as defined. However, your TestRepository implements your custom TestRepositoryBase<Test, int>. Therefore, you need to replace IRepository<Test, Int> by registering your concrete class.

Missing type map configuration or unsupported mapping. Mapping types: TestDetailsDTO -> Test Abc.Xyz.Business.Dto.Tests.TestDetailsDTO -> Abc.Xyz.Business.Model.Taxes.Test

Add [AutoMap(Test)] attribute on TestDetailsDTO.

If that doesn't work, try to manually configure the mapping:

public class MyTestModule : AbpModule
{
    public override void PreInitialize()
    {
        Configuration.Modules.AbpAutoMapper().UseStaticMapper = false;
        Configuration.Modules.AbpAutoMapper().Configurators.Add(config =>
        {
            config.CreateMap<TestDetailsDTO, Test>();
            config.CreateMap<Test, TestDetailsDTO>();
        });
    }
}
