Question

我正在尝试从基础开始，但无法理解如何创建此moq对象。

 public class TestRefMedicalSpecialty
{
    private Mock<IRepository<RefMedicalSpecialty>> mockRefMedicalRepo;

    public TestRefMedicalSpecialty()
    {
        var mockRefMedicalSpecialties = new List<RefMedicalSpecialty>
        {
            new RefMedicalSpecialty {Code = "10000", Description = "Medical Specialty1"},
            new RefMedicalSpecialty {Code = "10001", Description = "Medical Specialty2"},
            new RefMedicalSpecialty {Code = "10002", Description = "Medical Specialty3"}
        };

        mockRefMedicalRepo = new Mock<IRepository<RefMedicalSpecialty>>();

        mockRefMedicalRepo.Setup(repo => repo.GetAll()).Returns(mockRefMedicalSpecialties);

       // this.mockRefMedicalRepo = new Mock<IRepository<RefMedicalSpecialty>>().Object;
        this.mockRefMedicalRepo = mockRefMedicalRepo.Object;
    }

    [Fact]
    public void GetAll_Returns_Data()
    {

    }
}

严重级代码描述项目文件行抑制状态错误CS0266无法隐式转换类型＆＃39; Aamc.Ret.Data.IRepository<Aamc.Ret.Data.Models.RefMedicalSpecialty>＆＃39;到＆＃39; Moq.Mock<Aamc.Ret.Data.IRepository<Aamc.Ret.Data.Models.RefMedicalSpecialty>>＆＃39;。存在显式转换（您是否缺少演员？）Aamc.Ret.UnitTests

Answer 1

Mock<T>.Object属性返回泛型参数T的模拟。

因此，在您的情况下，mockRefMedicalRepo.Object是IRepository<RefMedicalSpecialty>，但您正尝试将其分配给Mock<IRepository<RefMedicalSpecialty>>，因为错误消息说明了这一点。

这是一个可能的替代方案

public class TestRefMedicalSpecialty {
    private IRepository<RefMedicalSpecialty> mockRefMedicalRepo;

    public TestRefMedicalSpecialty() {
        var mockRefMedicalSpecialties = new List<RefMedicalSpecialty>
        {
            new RefMedicalSpecialty {Code = "10000", Description = "Medical Specialty1"},
            new RefMedicalSpecialty {Code = "10001", Description = "Medical Specialty2"},
            new RefMedicalSpecialty {Code = "10002", Description = "Medical Specialty3"}
        };

        var mock = new Mock<IRepository<RefMedicalSpecialty>>();

        mock.Setup(_ => _.GetAll()).Returns(mockRefMedicalSpecialties);

        this.mockRefMedicalRepo = mock.Object;
    }

    [Fact]
    public void GetAll_Returns_Data() {

        //pass the mocked repo into a dependent class and 
        //exercise test that relies on calling GetAll

    }
}

我如何moq这个IRepository？
