我是.net core/C#编程的新手(来自Java)

我有以下Service类,它使用依赖注入来获取AutoMapper对象和数据存储库对象,以用于创建SubmissionCategoryViewModel对象的集合:

public class SubmissionCategoryService : ISubmissionCategoryService
{

    private readonly IMapper _mapper;

    private readonly ISubmissionCategoryRepository _submissionCategoryRepository;

    public SubmissionCategoryService(IMapper mapper, ISubmissionCategoryRepository submissionCategoryRepository)
    {

        _mapper = mapper;

        _submissionCategoryRepository = submissionCategoryRepository;

    }

    public List<SubmissionCategoryViewModel> GetSubmissionCategories(int ConferenceId)
    {


        List<SubmissionCategoryViewModel> submissionCategoriesViewModelList = 
            _mapper.Map<IEnumerable<SubmissionCategory>, List<SubmissionCategoryViewModel>>(_submissionCategoryRepository.GetSubmissionCategories(ConferenceId) );

        return submissionCategoriesViewModelList;


    }
}

我正在使用Xunit编写单元测试.我无法弄清楚如何编写方法GetSubmissionCategories一个单元测试,并有我的测试类提供一个IMapper实施和执行ISubmissionCategoryRepository.

到目前为止,我的研究表明我可以创建依赖对象的测试实现(例如SubmissionCategoryRepositoryForTesting),或者我可以使用模拟库来创建依赖关系接口的模拟.

但我不知道如何创建AutoMapper的测试实例或AutoMapper的模拟.

如果你知道任何好的在线教程,详细介绍如何创建一个单元测试,其中被测试的类使用AutoMapper和依赖注入数据存储库,这将是伟大的.

感谢您的帮助.

我正在为我的ASP .NET MVC Controller类创建一些单元测试,我遇到了一些非常奇怪的错误:

我的控制器代码如下:

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Delete(JournalViewModel journal)
{
    var selectedJournal = Mapper.Map<JournalViewModel, Journal>(journal);

    var opStatus = _journalRepository.DeleteJournal(selectedJournal);
    if (!opStatus.Status)
        throw new System.Web.Http.HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound));

    return RedirectToAction("Index");
}

我的测试代码如下:

[TestMethod]
public void Delete_Journal()
{
    // Arrange

    // Simulate PDF file
    HttpPostedFileBase mockFile = Mock.Create<HttpPostedFileBase>();
    Mock.Arrange(() => mockFile.FileName).Returns("Test.pdf");
    Mock.Arrange(() => mockFile.ContentLength).Returns(255);

    // Create view model to send.
    JournalViewModel journalViewModel = new JournalViewModel();
    journalViewModel.Id = 1;
    journalViewModel.Title = "Test";
    journalViewModel.Description = "TestDesc";
    journalViewModel.FileName = "TestFilename.pdf";
    journalViewModel.UserId = 1;
    journalViewModel.File = …
