在构造函数

我尝试在我的业务逻辑上编写单元测试。

我现在拥有的:

private Mock<IRepository<Theme>> _mockRepository;
    private IBaseService<Theme> _service;
    private Mock<IAdminDataContext> _mockDataContext;
    private List<Theme> _listTheme;

    [TestInitialize]
    public void Initialize()
    {
        _mockRepository = new Mock<IRepository<Theme>>();
        _mockDataContext = new Mock<IAdminDataContext>();
        _service = new ThemeService(_mockDataContext.Object);
        _listTheme = new List<Theme>
                     {
                         new Theme
                         {
                             Id = 1,
                             BgColor = "red",
                             BgImage = "/images/bg1.png",
                             PrimaryColor = "white"
                         },
                         new Theme
                         {
                             Id = 2,
                             BgColor = "green",
                             BgImage = "/images/bg2.png",
                             PrimaryColor = "white"
                         },
                         new Theme
                         {
                             Id = 3,
                             BgColor = "blue",
                             BgImage = "/images/bg3.png",
                             PrimaryColor = "white"
                         }
                     };
    }

    [TestMethod]
    public async Task ThemeGetAll()
    {
        //Arrange
        _mockRepository.Setup(x => x.GetAll()).ReturnsAsync(_listTheme);

        //Act
        List<Theme> results = await _service.GetAll();

        //Assert
        Assert.IsNotNull(results);
        Assert.AreEqual(_listTheme.Count, results.Count);
    }

问题 - 在服务GetAll上我得到异常,因为object为null。对象 - 这是存储库。以下是代码详细信息:

public class BaseService<T> : DomainBaseService, IBaseService<T> where T : BaseEntity
    {
        private readonly IAdminDataContext _dataContext;
        private readonly IRepository<T> _repository;

        public BaseService(IAdminDataContext dataContext)
            : base(dataContext)
        {
            this._dataContext = dataContext;
            this._repository = dataContext.Repository<T>();
        }

        public async Task<List<T>> GetAll()
        {
            return await _repository.GetAll();
        }
    }

如您所见,在服务中我尝试从unitOfWork(AdminDataContext)获取存储库。但它始终是空的。

我应该如何模拟我的服务以测试其功能?

您永远不会设置Repository方法来返回您的模拟存储库。只需将以下内容添加到&#34;安排&#34;部分考试:

_mockDataContext.Setup(x => x.Repository<Theme>()).Returns(_mockRepository.Object);
