FakeItEasy-期望一次或多次找到它，但未对伪造对象进行任何调用

Question

我有一个事件创建方法，该方法应该向我返回一个对象EventoDto，我正在使用fakeiteasy并使用值创建该对象，因为验证存在问题，现在这是我的代码。我应该如何进行这项测试？

[Fact]
public async void CreateEventSuccess_should_return_the_object_created()
{
    var dataEventDto = A.Fake<EventDto>();
    var createEvent = A.Fake<IEventService>();
    var objectEventDtoReturn = new EventDto();
    var eventService = new EventService(this.eventRepository, this.mapper);

    dataEventDto.Title = "this is a test for add event";
    dataEventDto.Description = "this is a description for the add event";
    dataEventDto.Venue = "this is the street";
    dataEventDto.Date = DateTime.Now;
    dataEventDto.Booking = true;
    dataEventDto.TypeEvent = EventType.Presential;
    dataEventDto.State = EventState.Published;
    dataEventDto.CancellationReason = "this is a test of cancellation event";
    dataEventDto.Url = "this is a url";

    A.CallTo(() => createEvent.Add(dataEventDto)).Returns(objectEventDtoReturn);

    await eventService.Add(dataEventDto);

    A.CallTo(() => createEvent.Add(dataEventDto)).MustHaveHappened();
}

此产生的错误是：

   Assertion failed for the following call:
        Assertion failed for the following call:
        Jalasoft.Events.Domain.Interfaces.Services.IService`2[Jalasoft.Events.Services.EventDto,System.String].Add(entity: Faked Jalasoft.Events.Services.EventDto)
      Expected to find it once or more but no calls were made to the fake object.

这是我正在测试的主题

private readonly IEventRepository repository;
private readonly IMapper mapper;
private EventValidator validator = new EventValidator();

public EventService(IEventRepository repository, IMapper mapper)
{
    this.repository = repository;
    this.mapper = mapper;
}

public async Task<EventDto> Add(EventDto entity)
{
    try
    {
        var results = this.validator.Validate(entity);
        bool success = results.IsValid;
        if (success)
        {
            Event eventMapper = this.mapper.Map<Event>(entity);
            var response = await this.repository.Add(eventMapper);
            EventDto eventDtoMapper = this.mapper.Map<EventDto>(response);
            return eventDtoMapper;
        }
        else
        {
            IList<ValidationFailure> failures = results.Errors;
            throw new ValidationException(failures);
        }
    }
    catch (Exception e)
    {
        throw new NotImplementedException(e.ToString());
    }
}

对于我正在使用https://automapper.org/的映射器，>

IEventService脚本

public interface IEventService : IService<EventDto, string>
{
}
Iservice脚本

public interface IService<T, TId>
    where T : EntityObject<TId>
{
    T GetById(TId id);

    Task<IEnumerable<T>> List();

    Task<T> Add(T entity);

    T Delete(T entity);

    T Edit(T entity);
}
IEventRepository脚本

public interface IEventRepository : IRepository<Event, ObjectId>
{
}
IRepository脚本

public interface IRepository<T, TId>

    Task<T> Add(T entity);

    T Delete(T entity);

    T Edit(T entity);
}
EventValidator脚本

        public EventValidator()
        {
            this.RuleFor(x => x.Title)
                .NotNull()
                .Length(10, 50)
                .WithMessage("Title shuold be 50 characteres like Max");
            this.RuleFor(x => x.Description)
                .NotNull()
                .Length(10, 500)
                .WithMessage("Description shuold be 500 characteres like Max");
            this.RuleFor(x => x.Booking)
                .NotNull()
                .WithMessage("Booking not null");
            this.RuleFor(x => x.Date)
                .Must(this.BeAValidDate).
                WithMessage("Is not a valid datetime");
            this.RuleFor(x => x.State == EventState.Cancelled || x.State == EventState.Published)
                .NotNull()
                .WithMessage("Is not a valid state");
            this.RuleFor(x => x.TypeEvent == EventType.Online || x.TypeEvent == EventType.Presential)
                .NotNull()
                .WithMessage("Is not a valid event type");
        }

[当前测试似乎正在尝试模拟被测对象。
