问如何在没有GlassController依赖注入的情况下对SitecoreContext操作进行单元测试

EN

public class HomeBottomContentController : GlassController
{
    // I want to test the EXACT method below
    public override ActionResult Index()
    {
        var context = new SitecoreContext();
        var model = context.GetCurrentItem<Home_Control>();
        return View("~/Views/HomeBottomContent/HomeBottomContent.cshtml", model);
    }

    /*
    // I do NOT want to have any of the below code for injecting ISitecoreContext into a constructor and testing the IndexTest() below it.
    private readonly ISitecoreContext _iSitecoreContext;
    public HomeBottomContentController(ISitecoreContext iSitecoreContext)
    {
        _iSitecoreContext = iSitecoreContext;
    }

    public HomeBottomContentController()
    { }

    public ActionResult IndexTest()
    {
        var model = _iSitecoreContext.GetCurrentItem<Home_Control>();
        return View("~/Views/HomeBottomContent/HomeBottomContent.cshtml", model);
