Question

我将Entity Framework 6与Code First一起使用，并且我想模拟DbContext进行单元测试。因为单元测试需要大量测试数据，所以我想使用Entity Framework Effort（https://entityframework-effort.net/）从csv文件加载它们。

我没有收到任何错误，但是我也没有从csv文件中获取任何数据。我得到的只是一个没有数据的DbContext（代码中的FapContext）。

您有解决我问题的建议吗？

使用NUnit进行单元测试：

    private FapContext context;
    private IUnitOfWork unitOfWork;
    private IDataLoader csvLoader;
    private IDataLoader dataLoader;

    [SetUp]
    public void SetUp()
    {
        this.csvLoader = new CsvDataLoader(@"C:\path\TestData\CSV-TestData");
        this.dataLoader = new CachingDataLoader(this.csvLoader, false);
        DbConnection connection = DbConnectionFactory.CreateTransient(this.dataLoader);

        try
        {
            this.context = new FapContext(connection);
            this.context.Database.CreateIfNotExists();
        }
        catch (Exception e)
        {
            Debug.Print(e.GetType().FullName);
            throw;
        }

        this.unitOfWork = new UnitOfWork(this.context);
    }

    [Test]
    public void ShouldReturnData()
    {
        // Arrange
        List<State> states = this.context.States.ToList();

        // Act

        // Assert
        Assert.IsNotNull(states);           // passes
        Assert.IsTrue(states.Count > 0);    // don't pass
    }

CSV文件：

ID,StateGroupID,Name,Description,CreatedAt,ChangedAt,RowVersion
"187968CE-0489-4A57-81F4-0BECDF9CC005","5FBAD179-68F5-46D2-A0A6-82516A3F2E4D","APPROVED","Approved material",,,
