How do I mock controller context in my unit test so that my RenderViewToString method works?

MVC

public static string RenderViewToString(ControllerContext context, string viewPath, object model = null, bool partial = false)
    {
        // first find the ViewEngine for this view
        ViewEngineResult viewEngineResult = null;
        if (partial)
            viewEngineResult = ViewEngines.Engines.FindPartialView(context, viewPath);
        else
            viewEngineResult = ViewEngines.Engines.FindView(context, viewPath, null);

        if (viewEngineResult == null)
            throw new FileNotFoundException("View not found.");

        // get the view and attach the model to view data
        var view = viewEngineResult.View;
        context.Controller.ViewData.Model = model;

        string result = null;
        using (var sw = new StringWriter())
        {
            var ctx = new ViewContext(context, view, context.Controller.ViewData, context.Controller.TempData, sw);
            view.Render(ctx, sw);
            result = sw.ToString();
        }
        return result;

    }

I want to Test this method but i am not able to build/Mock ControllerContext as required for it. Can anyone help for it?
