如何更改被嘲笑的对象？

Question

在我的单元测试中，我需要更改之前模拟的对象的值。例如：

public class Cell
{
    public int X { get; set; }
    public int Y { get; set; }
    public string Value { get; set; }
}

public class Table
{
    private Cell[,] Cells { get; }

    public Table(Cell[,] cells)
    {
        Cells = cells;
    }

    public void SetCell(int x, int y, string value)
    {
        Cells[x, y].Value = value;
    }
}

我想在 Table 中测试 SetCell 方法。

所以，首先我模拟 Cell，然后我创建一个 Cell[,] 单元格数组，创建一个 Table 传递单元格数组作为参数。

SetCell 不起作用，因为（我认为）我无法更改之前被模拟的对象。我该如何改变它？

这是我的测试：

ICell[,] cells = new ICell[3, 4];
for (int i = 0; i < cells.GetLength(0); i++)
{
    for (int j = 0; j < cells.GetLength(1); j++)
    {
        var mock = new Mock<ICell>();
        mock.Setup(m => m.X).Returns(i);
        mock.Setup(m => m.Y).Returns(j);
        mock.Setup(m => m.Value).Returns("");

        cells[i, j] = mock.Object;
    }
}            


ITable table = new Table(cells);
table.SetCell(0, 0, "TEST"); // Cannot change it here :/

Setup all the properties 以便更新

ICell[,] cells = new ICell[3, 4];
for (int i = 0; i < cells.GetLength(0); i++)
{
    for (int j = 0; j < cells.GetLength(1); j++)
    {
        var mock = new Mock<ICell>();
        mock.SetupAllProperties();
        mock.Object.X = i;
        mock.Object.Y = j;
        mock.Object.Value = "";

        cells[i, j] = mock.Object;
    }
}
