尝试对构造函数参数进行单元测试时传递错误

Question

X单元测试课程

       public class JournalHistoryPageViewModelTests
               {
                  private readonly JournalHistoryPageViewModel _journalHistoryPageViewModel;
                 private readonly Mock<IJournalHistoryService> _journalHistoryService;


                   public   JournalHistoryPageViewModelTests()
                   {

            _journalHistoryService = new Mock<IJournalHistoryService>();
            _journalHistoryPageViewModel = new JournalHistoryPageViewModel(_journalHistoryService.Object);
            _journalHistoryService.SetupGet<Task<List<JournalModel>>>(m => m.GetJounralsAsync(It.IsAny<PatientViewModel>(),It.IsAny<int> 
              (),It.IsAny<FilterType>(),It.IsAny<JournalType>())).**Returns(new Task<List<JournalModel>>());**

            BaseClassValuesUpdate();


                        }


private void BaseClassValuesUpdate()
{
    _journalHistoryPageViewModel.JournalGroup = new JournalGroup() { Type = JournalType.Documents };
    var patientViewModel = new PatientViewModel(new PatientInfo());

    _journalHistoryPageViewModel.SelectedPatient=patientViewModel;
}

我收到此错误，我认为问题以粗体显示 谁能建议该怎么做

严重性代码描述项目文件行抑制状态 错误CS1729'任务'不包含带有0个参数的构造函数DipsDemoXaml.XUnitTest C：\ Users \ Ishara.M \ source \ repos \ Visit-Xamarin.Forms \ DipsDemoXaml.XUnitTest \ ViewModelTest \ JournalHistoryPageViewModelTests.cs 28活动

我的日记模型

public class JournalModel
      {
public string Title { get; set; }
public DateTime DateTime { get; set; }
public string Author { get; set; }
public string PatientId { get; set; }
public string DateTimeFormated { get; set; }
public JournalType Type { get; set; } 
public string Uri { get; set; }


 }

此处IJournalHistoryService.cs

     public interface IJournalHistoryService
     {



Task<List<JournalModel>> GetJounralsAsync(PatientViewModel patient, int pageNumber, FilterType sortingMethod, JournalType journalType);



/// <summary>
/// Retrieves Count of Documents to respective Patient 
/// </summary>
/// <param name="patient">Patient</param>
/// <returns>CountofDocuments</returns>
int GetJournalsCount(PatientViewModel patient, JournalType journalType);

/// <summary>
/// Sorts Documents according to sortingType
/// </summary>
/// <param name="sortingMethod">Page Method of Sorting</param>
void SortByType(FilterType sortingType);

}
